Autologous breast reconstruction with the extended latissimus dorsi flap

The extended latissimus dorsi myocutaneous flap can provide autogenous tissue replacement of breast volume without an implant. Nevertheless, experience with the extended latissimus dorsi flap for breast reconstruction is relatively limited. In this study, the authors evaluated their experience with the extended latissimus dorsi flap for breast reconstruction to better understand its indications, limitations, complications, and clinical outcomes. All patients who underwent breast reconstruction with extended latissimus dorsi flaps at the authors' institution between January of 1990 and December of 2000 were reviewed. During the study period, 75 extended latissimus dorsi flap breast reconstructions were performed in 67 patients. Bilateral breast reconstructions were performed in eight patients, and 59 patients underwent unilateral breast reconstruction. There were 45 immediate and 30 delayed reconstructions. Mean patient age was 51.5 years. Mean body mass index was 31.8 kg/m2. Flap complications developed in 21 of 75 flaps (28.0 percent), and donor-site complications developed in 29 of 75 donor sites (38.7 percent). Mastectomy skin flap necrosis (17.3 percent) and donor-site seroma (25.3 percent) were found to be the most common complications. There were no flap losses. Patients aged 65 years or older had higher odds of developing flap complications compared with those 45 years or younger (p = 0.03). Patients with size D reconstructed breasts had significantly higher odds of flap complications compared with those with size A or B reconstructed breasts (p = 0.05). Obesity (body mass index greater than or equal to 30 kg/m2) was associated with a 2.15-fold increase in the odds of developing donor-site complications compared with patients with a body mass index less than 30 kg/m2 (p = 0.01). No other studied factors had a significant relationship with flap or donor-site complications. In most patients, the extended latissimus dorsi flap alone, without an implant, can provide good to excellent autologous reconstruction of small to medium sized breasts. In selected patients, larger breasts may be reconstructed with the extended latissimus dorsi flap alone. This flap's main disadvantage is donor-site morbidity with prolonged drainage and risk of seroma. Patients who are obese are at higher risk of developing these donor-site complications. In conclusion, the extended latissimus dorsi flap is a reliable method for total autologous breast reconstruction in most patients and should be considered more often as a primary choice for breast reconstruction.     

Trends in unilateral breast reconstruction and management of the contralateral breast: the Emory experience

Recent trends in breast reconstruction have transitioned toward the skin-sparing type of mastectomy and immediate reconstruction using autologous tissue. This study was designed to document trends in the management of patients with unilateral breast cancer and to determine how they influence management of the contralateral breast.All patients who underwent unilateral breast reconstruction at Emory University Hospitals from January of 1975 to December of 1999 were reviewed. The cohort was stratified by timing of reconstruction (immediate versus delayed), method of reconstruction, and mastectomy type (skin-sparing versus non-skin-sparing). The methods of reconstruction included implant, latissimus dorsi flap, and transverse rectus abdominis musculocutaneous (TRAM) flap. Contralateral procedures to achieve symmetry included augmentation, mastopexy, augmentation/mastopexy, and reduction. A total of 1394 patients were evaluated, including 689 delayed and 705 immediate reconstructions. Sixty-seven percent of delayed-reconstruction patients (462 of 689) had a symmetry procedure performed on the opposite breast, compared with 22 percent for the immediate-reconstruction patients (155 of 705) (p 相似文献   

Thoracodorsal vessels as recipient vessels for the free TRAM flap in delayed breast reconstruction.

The internal mammary vessels have been recommended as the first choice recipient vessels for delayed breast reconstruction with the free TRAM flap. This approach has avoided surgery in the previously operated axilla, has required a shorter pedicle length, and has allowed for more medial placement of the TRAM tissue. Frequency of nonusable axillary vessels has been reported at 11 percent, with a 6 percent incidence of flap loss in the delayed reconstructive setting. We reviewed our experience with the thoracodorsal vessels as recipient vessels in delayed free TRAM breast reconstruction to assess more accurately the adequacy of these potential recipient vessels. All patients undergoing delayed TRAM reconstruction were reviewed. Forty-seven of 300 consecutive TRAM procedures were for planned delayed free reconstruction. In seven of the patients (15 percent), the thoracodorsal vessels were found to be inadequate for free reconstruction. A supercharged pedicled TRAM was used for reconstruction in each of these seven patients. Average operating room time was 7 hours. Mean follow-up time was 38 months. Nineteen percent of all patients developed at least one complication. Twelve percent of free TRAM patients developed a complication, whereas 57 percent of supercharged patients developed a postoperative complication. The difference in complication rates was statistically significant. The thoracodorsal vessels have provided an adequate recipient vessel in 85 percent of delayed free TRAM reconstructions, comparable to previous reports. Pedicling and supercharging the flap, in those situations in which the thoracodorsal vessels were inadequate, were associated with an increased incidence of postoperative complications. This suggests that in the delayed reconstructive setting, higher-risk patients benefit from free reconstruction over supercharged reconstructions. A second recipient vessel should be used when the thoracodorsal vessels are inadequate for planned free TRAM reconstruction. In these circumstances, we would recommend the use of the internal mammary vessels followed by the thoracoacromial vessels as reliable alternative recipient sites for delayed free TRAM reconstruction.     

Prospective analysis of psychosocial outcomes in breast reconstruction: one-year postoperative results from the Michigan Breast Reconstruction Outcome Study

In the past decade, changing attitudes toward breast reconstruction among both patients and providers have led a growing number of women to seek breast reconstruction after mastectomy. Although investigators have documented the psychological, social, emotional, and functional benefits of breast reconstruction, little research has evaluated the effects of procedure choice on these outcomes. The current study prospectively evaluated and compared psychosocial outcomes for three common options for mastectomy reconstruction: tissue expander/implant, pedicle TRAM, and free TRAM techniques. In a prospective cohort design, patients undergoing postmastectomy reconstruction for the first time with expander/implant, pedicle TRAM, or free TRAM procedures were recruited from 12 centers and 23 plastic surgeons in the United States and Canada. Before reconstruction and at 1 year after reconstruction, patients were evaluated by a battery of questionnaires consisting of both generic and condition-specific surveys. Outcomes assessed included emotional well-being, vitality, general mental health, social functioning, functional well-being, social well-being, and body image. Baseline (preoperative) scores and the change in scores (the difference between postoperative and preoperative scores) were compared across procedure types using t tests and analysis of covariance. Preoperative and 1-year postoperative surveys were obtained from 273 patients. Procedure type was reported in 250 patients, of whom 56 received implant reconstructions, 128 pedicle TRAM flaps, and 66 free TRAM flaps. A total of 161 immediate and 89 delayed reconstructions were performed. Among women receiving immediate reconstruction, significant improvements were observed in all psychosocial variables except body image. However, no significant effects of procedure type on these changes over time existed. Similarly, delayed reconstruction patients had significant increases in emotional well-being, vitality, general mental health, functional well-being, and body image. Although the choice of reconstructive technique did not significantly impact most of these outcomes, significant differences existed among procedure types for three psychosocial subscales. Patients undergoing delayed expander/implant reconstructions reported greater improvements in vitality and social well-being relative to women receiving delayed TRAM procedures. By contrast, delayed TRAM patients noted significantly greater gains in body image compared with women choosing delayed expander-implant reconstruction. The authors conclude that both immediate and delayed breast reconstructions provide substantial psychosocial benefits for mastectomy patients. Although the choice of reconstructive procedure does not seem to significantly affect improvements in psychosocial status with immediate reconstruction, our data suggest that procedure type does have a significant effect on gains in vitality and body image for women undergoing delayed reconstruction.     

Latissimus dorsi myocutaneous flap for breast reconstruction: long-term results.

A review was performed on 170 patients who underwent 173 consecutive latissimus dorsi myocutaneous flap breast reconstructions between 1978 and 1989. The majority of the patients had modified radical mastectomies, and reconstruction was usually delayed for 3 to 18 months after mastectomy. Acceptable symmetry was obtained in the majority of patients without the need for surgery on the opposite breast. Perioperative and long-term complications are reviewed. Patients were followed for an average of 4.7 years after reconstruction. Ninety-four percent of patients demonstrated little or no change in the reconstructed breast after the first year. This method of reconstruction has met patient expectations with a minimum number of procedures and low morbidity.     

Breast reconstruction in older women: advantages of autogenous tissue

As the population ages, the treatment of breast cancer among elderly women is becoming increasingly common. Decisions with regard to breast reconstruction require not only consideration of patient age and comorbidities but also a need to balance life expectancy with quality of life. Although it is often assumed that implant-based breast reconstruction is the least disruptive method, especially among patients who may be facing limited survival times, it was hypothesized that autogenous tissue breast reconstruction is a well-tolerated and perhaps preferable means of reconstruction for older women who choose to undergo reconstruction following mastectomy. No large series of autogenous tissue reconstructions in this age group has been presented. A retrospective study of 84 postmastectomy reconstructions (66 unilateral and 18 bilateral; 78.6 percent immediate) performed at the authors' institution for 81 women 65 years of age or older, between April of 1987 and December of 2000, was undertaken. Reconstructions were implant-based ( = 26), latissimus dorsi flap-based ( = 24), or transverse rectus abdominis myocutaneous (TRAM) flap-based ( = 34). Of the 34 TRAM flaps, 21 were free or supercharged. Breast complications were more frequent ( < 0.05) among recipients of implant-based reconstructions (76.9 percent) than among recipients of latissimus dorsi flap (41.7 percent) or TRAM flap (35.3 percent) reconstructions. In multivariate logistic regression analyses, comorbidities, smoking, radiotherapy, and body mass index had no effect. Medical complications without long-term sequelae were observed for two patients who underwent latissimus dorsi flap reconstructions and two patients who underwent free TRAM flap reconstructions; the difference in the rates of medical complications was not significant. At the mean follow-up time of 4.2 years, 92.8 percent of all study patients exhibited no evidence of disease. Notably, despite being free of disease, seven of the 26 patients (27 percent) who underwent implant-based reconstructions abandoned further reconstructive efforts after complications necessitated implant removal. It was concluded that age alone should not determine the type of breast reconstruction and that autogenous tissue breast reconstruction can be a safe successful alternative for women 65 years of age or older.     

Breast reconstruction in women treated with radiation therapy for breast cancer: cosmesis, complications, and tumor control.

The records of 55 patients who had breast cancer treated by mastectomy, irradiation, and breast reconstruction were reviewed for cosmetic outcome, complications, and tumor control. Median follow-up was 35 months. Local control rates were 95 percent in patients treated for high risk factors or breast conservation and 85 percent in patients treated for recurrent breast cancer. Acceptable cosmetic results were obtained in only 42 percent of patients. The incidence of complications was 55 percent. Transverse rectus abdominis muscle (TRAM) reconstructions gave superior cosmetic results compared with all other types of reconstructions. The timing of reconstruction in relation to mastectomy or radiation therapy did not significantly influence cosmetic outcome, although other factors suggest that delayed reconstruction may give better results. A majority of patients were satisfied with cosmetic outcome.     

Bilateral autogenous breast reconstruction using perforator free flaps: a single center's experience

The authors present a single center's experience in bilateral breast reconstruction using perforator free flaps. The aim of this study was to show their indications, surgical technique, and results. A series of 53 patients underwent this procedure between February of 1996 and October of 2002. The surgical procedures were performed on patients with bilateral breast cancer (11 patients), patients with unilateral breast cancer and contralateral prophylactic mastectomy (22 patients), patients who had undergone bilateral prophylactic mastectomy (18 patients), a patient with Poland's syndrome, and a patient whose aesthetic breast augmentation had failed. Primary and secondary bilateral breast reconstructions were done in 18 and four patients, respectively. Eighteen patients who had earlier undergone breast reconstruction with implants had a tertiary breast reconstruction. Combined reconstruction (primary with secondary and primary with tertiary reconstruction) was done in 13 patients. Ninety-eight deep inferior epigastric perforator flaps and eight superior gluteal artery perforator flaps were used. The average operative time was 10 hours (range, 8 to 14.5 hours) for the simultaneous bilateral reconstruction. Total flap necrosis occurred in two cases (one deep inferior epigastric perforator flap and one superior gluteal artery perforator flap). Partial flap necrosis was not encountered, and fat necrosis was found in one deep inferior epigastric perforator flap (1 percent). Two pulmonary infections, one deep vein thrombosis, and one cardiac arrhythmia occurred as postoperative complications. The mean hospital stay was 9 days (range, 6 to 20 days). Abdominal bulging was reported in one patient. There were no recurrent disease or cancer manifestations, with an average follow-up of 3.5 years. This series clearly shows that perforator flaps are reliable and useful tools for bilateral breast reconstruction. This technique decreases the donor-site morbidity and offers an excellent aesthetic and long-term outcome and high patient satisfaction.     

Comparison of cost for DIEP and free TRAM flap breast reconstructions

A recent article by Kaplan and Allen suggested that deep inferior epigastric perforator (DIEP) flap breast reconstruction was less expensive than reconstruction performed with free transverse rectus abdominis musculocutaneous (TRAM) flaps. To test that hypothesis, a series of patients who had undergone unilateral breast-mound reconstruction by the first author using DIEP or free TRAM flaps between November 1, 1996, and March 30, 2000, were reviewed. Bilateral reconstructions and reconstructions performed by other surgeons in the department were excluded to eliminate all variables except the choice of flap. All hours in the operating room and days in the hospital until discharge were included. Early readmissions for the treatment of complications were included, as were the costs of the mastectomy in the case of immediate reconstructions, but late revisions and nipple reconstructions were not. The totals were then converted into resource costs in 1999 dollars, and the DIEP and free TRAM flap groups compared. There were 21 DIEP flaps and 24 free TRAM flaps in the series. In this series, there was no significant difference between the cost of DIEP and free TRAM flap breast reconstruction.     

An outcome analysis comparing the thoracodorsal and internal mammary vessels as recipient sites for microvascular breast reconstruction: a prospective study of 100 patients

The thoracodorsal vessels have been the standard recipient vessels for the majority of surgeons performing free transverse rectus abdominis musculocutaneous (TRAM) flap reconstructions. Recently, the internal mammary vessels have been recommended as the first-choice recipient vessels for microvascular breast reconstruction. This approach requires a shorter pedicle length, allows for central placement of flap tissue, and avoids axillary scarring. The use of the internal mammary vessels may provide for a shorter operative time and a higher-quality aesthetic reconstruction. The authors performed a prospective trial examining the differences in operative and aesthetic outcomes between each recipient site. A prospective trial of 108 consecutive free-tissue transfers was conducted in 100 patients. The first 60 TRAM flap patients were randomized so that 30 flaps were anastomosed to the internal mammary vessels and 30 were anastomosed to the thoracodorsal vessels, whereas the recipient vessels for the remaining 40 patients were left to the discretion of the surgeon. Of the 40 nonrandomized patients, 10 patients underwent reconstruction using the internal mammary vessels and 30 patients underwent reconstruction using the thoracodorsal vessels. The patients' medical history and hospital course were noted. To evaluate aesthetic outcome, a group of five blinded nonmedical observers and three blinded plastic surgeons graded the reconstructions in the 60 TRAM flap patients for symmetry and overall aesthetic result on a scale of 1 to 5. Blinded practitioners administered postoperative questionnaires to patients regarding recovery time and satisfaction with the aesthetic result. Forty-three flaps were transferred to the internal mammary vessels and 65 were transferred to the thoracodorsal vessels. No significant differences existed between groups with regard to age of preoperative risk factors. Average operative time was 6 hours in each group. Average hospital stay was 5.8 days in each group. Conversion from initial recipient vessel to a secondary recipient site occurred in 12.5 percent of internal mammary reconstructions and 7 percent of thoracodorsal reconstructions. All converted internal mammary cases occurred in left-sided reconstructions and were attributable to problems with the veins. Overall, 20 percent of left-sided internal mammary reconstructions were found to have an inadequate recipient vein. Unusable thoracodorsal vessels were found only in delayed reconstructions, at a rate of 15 percent in the delayed setting. All flaps from converted procedures survived without complications. Average follow-up was 20 months, during which time there was one flap loss in the thoracodorsal group. There were no significant differences in complication rates between groups. Average aesthetic grade was 3.6 in each group. Postoperative recovery time and overall patient satisfaction were not significantly different between groups. Either recipient site can provide for a safe and acceptable result; however, surgeons should be aware of conversion rates and plan appropriately if recipient vessels appear unusable for free-tissue transfer.     

Resource cost comparison of implant-based breast reconstruction versus TRAM flap breast reconstruction

Relatively little has been published to date comparing the resource costs of transverse rectus abdominis musculocutaneous (TRAM) flap and prosthetic breast reconstruction. The data that have been published reflect the experience at just one medical center with a previously known clear preference for autologous breast reconstruction. The goal of this study was to compare the resource costs of TRAM flap and prosthetic reconstruction in an institution where both procedures continue to be performed using modern techniques and at a relatively equivalent frequency. All available medical records were reviewed for patients who had completed their breast reconstruction between 1987 and 1997. Records of patients who had undergone TRAM flap or prosthetic reconstruction were reviewed to compare resource costs, including hospital stay, operating room time, anesthesia time, prosthetic devices, and physician's fees. Of 835 patients reviewed who had completed breast reconstruction, a total of 140 suitable patients were identified who had all the necessary financial information available. The patient population comprised 64 patients who received TRAM flaps and 76 patients who had undergone prosthetic reconstruction. The length of stay for the TRAM flap group, including all subsequent admissions for each patient, ranged from 2 to 24 days (mean, 6.25 days), and that for the prosthetic reconstruction group ranged from 0 to 20 days (mean, 4.36 days). Operating room time for the complete multistage reconstructive process for a TRAM flap ranged from 5 hours, 20 minutes to 12 hours, 25 minutes (mean, 7 hours, 34 minutes); with implant-based reconstruction, operating time ranged from 1 hour, 45 minutes to 8 hours, 56 minutes (mean, 4 hours, 6 minutes). With prostheses costing from $600 to $1200, a surgeon's fee of $160/hour, and an assistant's fee of $45/hour, the average cost of TRAM flap reconstructions was $19,607 (range, $11,948 to $49,402), compared with $15,497 for prosthetic reconstructions (range, $6422 to $40,015). The results were statistically significant (p < 0.001). Several factors weigh into the decision as to which reconstructive operation best suits the patient's needs. These factors include surgical risk, potential morbidity, and aesthetic results. On the basis of this review of autologous and prosthetic breast reconstruction in an institution where both are performed frequently, during a 10-year period with a mean time elapsed since reconstruction of 7.45 years, prosthetic reconstruction was significantly less expensive.     

Nasal reconstruction--beyond aesthetic subunits: a 15-year review of 1334 cases

A retrospective analysis was performed on 1334 patients who underwent nasal reconstruction between 1986 and 2001. The senior author performed all reconstructions in this series after Mohs' histographic excisions. Only secondary reconstructions were performed without a preceding Mohs' excision. Methods of reconstruction, number of operations per patient, locations of defects, and complications were recorded. Using preoperative and postoperative photographs, aesthetic results were reviewed. Basal cell carcinoma was the most common lesion, followed by squamous cancer and melanoma. The average age of the patients was 51 years. Cancers most commonly arose on the dorsum, ala, and tip. Of 1334 cases, a 1.9 percent recurrence rate was documented. The average time between surgery and clinical recognition of recurrence was 39 months. All recurrent lesions were reexcised by the Mohs' technique. Eighty-one percent of reconstructions were completed in three or fewer stages. Seventy-five percent of reconstructions were completed in two stages. Primary dermabrasion or primary laserbrasion using carbon dioxide or erbium lasers was used in nearly every case. Early secondary dermabrasion or laserbrasion was used in a few cases where indicated. A 1.2 percent revision rate was noted (16 patients). Thirteen partial flap necroses required revision. Three patients experienced dehiscence at the donor site of paramedian forehead flaps. A preferred philosophy toward nasal reconstruction is described. The goal is to achieve optimal cosmetic and functional results while minimizing stages and resection of healthy tissue. Six core principles are advocated that guide efficient and successful nasal reconstruction: (1) maximal conservation of native tissue is advised; (2) reconstruction of the defect, not the subunit, is advised; (3) complementary ablative procedures, such as primary dermabrasion, enhance the final result and decrease the number of revisionary procedures; (4) primary defatting also decreases the number of revisionary procedures; (5) when possible, the use of axial pattern flaps is preferred; and (6) good contour is the aesthetic endpoint.     

Outcome comparison between free and pedicled TRAM flap breast reconstruction in the obese patient.

Obesity can be a contraindication for TRAM flap breast reconstruction. This study reviewed the authors' experience with free TRAM and pedicled TRAM flap breast reconstruction in the obese patient to examine the complication rates associated with each reconstructive method and to determine whether TRAM flap reconstruction can safely be used in these high-risk patients. The records of 221 consecutive TRAM flap reconstructions were reviewed. Preoperative risk factors for morbidity were noted, as well as the incidence of TRAM flap success, operative time, length of hospital stay, and postoperative complications. Patients were categorized as obese if their body mass index was greater than 25.8 kg/m2. Data were tabulated using contingency tables and analyzed using chi-squared statistics. Multiple logistic regression was used to determine risk factors for flap complications.Of the 221 patients studied, 114 patients were found to be obese (body mass index >25.8 kg/m2). Of these 114 patients, 78 were reconstructed with free TRAM flaps and 36 were reconstructed with pedicled flaps. In these obese patients, the average body mass index was 32 kg/m2 in the free TRAM and 30 kg/m2 in the pedicled TRAM flap reconstructions. There were no significant differences between groups with regard to age or preoperative risk factors. Length of hospital stay and operative time did not differ significantly between the two reconstructive methods. The average duration of follow-up was 24 months in both groups. Complications occurred in 26 percent of free TRAM flap reconstructions and 33 percent of pedicled reconstructions. There was no significant difference between reconstructive methods with regard to overall complication rates. Increasing body mass index was found to have a significant effect on free TRAM flap complications (p = 0.008) but not on pedicled TRAM flap complications. There were no partial or total flap losses in obese free TRAM flap patients; however, there was one case of total flap loss and four cases of partial flap loss in the obese pedicled TRAM flap group. The incidence of flap loss was significantly higher when pedicled TRAM flaps were used for reconstruction in obese patients (p = 0.04). Obese patients who underwent reconstruction with pedicled TRAM flaps were more likely to experience a complication if they also smoked (p = 0.001).There was no significant difference in operating time or length of stay when pedicled and free TRAM flap reconstructions in obese patients were compared. There were more cases of flap necrosis in the pedicled TRAM flap group. Free TRAM flaps may provide some benefit in reducing partial flap loss in obese patients, but overall complication rates were not significantly different between reconstructive methods. Of 114 patients, there was only one case of total reconstructive failure. From these findings, it seems that the free or pedicled TRAM flap can be used successfully for breast reconstruction in the majority of patients with obesity. Surgeons should use the technique with which they are most familiar to obtain consistent results.     

Delayed-immediate breast reconstruction

In patients with early-stage breast cancer who are scheduled to undergo mastectomy and desire breast reconstruction, the optimal timing of reconstruction depends on whether postmastectomy radiation therapy will be needed. Immediate reconstruction offers the best aesthetic outcomes if postmastectomy radiation therapy is not needed, but if postmastectomy radiation therapy is required, delayed reconstruction is preferable to avoid potential aesthetic and radiation-delivery problems. Unfortunately, the need for postmastectomy radiation therapy cannot be reliably determined until review of the permanent tissue sections. The authors recently implemented a two-stage approach, delayed-immediate breast reconstruction, to optimize reconstruction in patients at risk for requiring postmastectomy radiation therapy when the need for postmastectomy radiation therapy is not known at the time of mastectomy. Stage 1 consists of skin-sparing mastectomy with insertion of a completely filled textured saline tissue expander. After review of permanent sections, patients who did not require post-mastectomy radiation therapy underwent immediate reconstruction (stage 2) and patients who required postmastectomy radiation therapy completed postmastectomy radiation therapy and then underwent standard delayed reconstruction. In this study, the feasibility and outcomes of this approach were reviewed. Fourteen patients were treated with delayed-immediate reconstruction between May of 2002 and June of 2003. Twelve patients had unilateral reconstruction and two patients had bilateral reconstruction, for a total of 16 treated breasts. All patients completed stage 1. Tissue expanders were inserted subpectorally in 15 breasts and subcutaneously in one breast. The mean intraoperative expander fill volume was 475 cc (range, 250 to 750 cc). Three patients required postmastectomy radiation therapy and underwent delayed reconstruction. Eleven patients did not require postmastectomy radiation therapy. Nine patients had 11 breast reconstructions (stage 2), six with free transverse rectus abdominis musculocutaneous (TRAM) flaps, one with a superior gluteal artery perforator flap, and four with a latissimus dorsi flap plus an implant. The median interval between stages was 13 days (range, 11 to 22 days). Two patients who did not require postmastectomy radiation therapy have not yet had stage 2 reconstruction, one because she wished to delay reconstruction and the other because she required additional tissue expansion before permanent implant placement. Six complications occurred. The stage 1 complications involved two cases of mastectomy skin necrosis in patients who required post-mastectomy radiation therapy; one patient required removal of the subcutaneously placed expander before postmastectomy radiation therapy and the other patient had a subpectorally placed expander that only required local wound care. The stage 2 complications were a recipient-site seroma in a patient with a latissimus dorsi flap, a recipient-site hematoma in the patient with the superior gluteal artery perforator flap, and two arterial thromboses in patients with TRAM flaps. Both TRAM flaps were salvaged. Delayed-immediate reconstruction is technically feasible and safe in patients with early-stage breast cancer who may require postmastectomy radiation therapy. With this approach, patients who do not require postmastectomy radiation therapy can achieve aesthetic outcomes essentially the same as those with immediate reconstruction, and patients who require postmastectomy radiation therapy can avoid the aesthetic and radiation-delivery problems that can occur after an immediate breast reconstruction.     

Delay in unipedicled TRAM flap reconstruction of the breast: a review of 76 consecutive cases

Since its introduction in 1982, the transverse rectus abdominis musculocutaneous (TRAM) flap has become the standard therapy in autogenous breast reconstruction. A lower rate of partial flap (fat) necrosis is associated with microvascular free-flap transfer compared with the conventional (unipedicled) TRAM flap because of its potentially improved blood supply. A TRAM flap delay before flap transfer has been advocated, especially in a high-risk patient population (obesity, history of cigarette smoking, radiation therapy, or abdominal scar). The authors reviewed a series of 76 consecutive delayed unipedicled TRAM flap breast reconstructions during a 5-year period. Data were analyzed with respect to type of procedure and time of delay, overall outcome, general surgical complications, flap-related (specific) complications (partial or complete flap loss), and patient satisfaction. Seventy-six unilateral breast reconstructions using the unipedicled TRAM flap were performed between 1995 and 2000 in 76 patients (mean age, 47.4 years). Fifty-four flaps were performed as immediate reconstructions, and 22 as secondary procedures. Seventy-two flaps were based on the contralateral pedicle, and four flaps were based on an ipsilateral pedicle. In all cases, a flap delay consisted of ligature of both deep inferior epigastric arteries and veins, accessed from an inferior flap incision down to the fascia, with a mean of 13.9 days before the flap transfer. No acute flap take-back procedure had to be performed. There was no complete flap loss, and breast reconstruction was achieved in all cases. In five cases (6.6 percent), a partial (fat) flap necrosis occurred. Interestingly, the majority of these cases (four of five) were secondary breast reconstructions. In addition, of the five patients who had partial flap necrosis, four had a history of smoking, two received radiation therapy, three received chemotherapy, and three patients were obese (body mass index greater than or equal to 30) or overweight (body mass index greater than or equal to 25). In three cases, an early surgical complication (two wound infections at the flap interface and one at the donor site) occurred. One patient developed a deep vein thrombosis. Five patients developed secondary ventral hernias necessitating repair (6.6 percent). Forty-one patients underwent secondary nipple-areola reconstruction. In 19 patients of this group, a secondary procedure (e.g., scar revision, limited liposuction, and/or excision of contour deformities) was simultaneously performed. A survey of patient satisfaction was performed using a modified SF-36 questionnaire. Fifty-one patients participated (67 percent). The overall satisfaction was very high and 51 patients reported that they would recommend the procedure to others (100 percent). Multiple factors such as patient selection, surgical expertise, and preoperative and postoperative management contribute to the success of any type of autogenous breast reconstruction. However, rare partial and absent complete flap necrosis in the authors' series may be attributable to the flap delay. A low morbidity rate and short hospital stay may become increasingly relevant, with limited structural and financial resources in the future. Therefore, the delayed unipedicled TRAM flap should be regarded as a valuable option in attempted breast reconstruction using autogenous tissue in both a high-risk and the general patient population.     

Comparison of immediate and delayed free TRAM flap breast reconstruction in patients receiving postmastectomy radiation therapy.

Tumor pathologic features and the extent of nodal involvement dictate whether radiation therapy is given after mastectomy for breast cancer. It is generally well accepted that radiation negatively influences the outcome of implant-based breast reconstruction. However, the long-term effect of radiation therapy on the outcome of breast reconstruction with the free transverse rectus abdominis myocutaneous (TRAM) flap is still unclear. For patients who need postmastectomy radiation therapy, the optimal timing of TRAM flap reconstruction is controversial. This study compares the outcome of immediate and delayed free TRAM flap breast reconstruction in patients who received postmastectomy radiation therapy.All patients at The University of Texas M. D. Anderson Cancer Center who received postmastectomy radiation therapy and who also underwent free TRAM flap breast reconstruction between January of 1988 and December of 1998 were included in the study. Patients who received radiation therapy before delayed TRAM flap reconstruction were compared with patients who underwent immediate TRAM flap reconstruction before radiation therapy. Early and late complications were compared between the two groups. Early complications included vessel thrombosis, partial or total flap loss, mastectomy skin flap necrosis, and local wound-healing problems, whereas late complications included fat necrosis, volume loss, and flap contracture of free TRAM breast mounds. Late complications were evaluated at least 1 year after the completion of radiation therapy for patients who had delayed reconstruction and at least 1 year after reconstruction for patients who had immediate reconstruction.During the study period, 32 patients had immediate TRAM flap reconstruction before radiation therapy and 70 patients had radiation therapy before TRAM flap reconstruction. Mean follow-up times for the immediate reconstruction and delayed reconstruction groups were 3 and 5 years, respectively. The mean radiation dose was 50 Gy in the immediate reconstruction group and 51 Gy in the delayed reconstruction group.One complete flap loss occurred in the delayed reconstruction group, and no flap loss occurred in the immediate reconstruction group. The incidence of early complications did not differ significantly between the two groups. However, the incidence of late complications was significantly higher in the immediate reconstruction group than in the delayed reconstruction group (87.5 percent versus 8.6 percent; p = 0.000). Nine patients (28 percent) in the immediate reconstruction group required an additional flap to correct the distorted contour from flap shrinkage and severe flap contraction.These findings indicate that, in patients who are candidates for free TRAM flap breast reconstruction and need postmastectomy radiation therapy, reconstruction should be delayed until radiation therapy is complete.     

Complications in postmastectomy breast reconstruction: two-year results of the Michigan Breast Reconstruction Outcome Study

In this study, the effects of procedure type, timing, and other clinical variables on complication rates in mastectomy reconstruction were prospectively evaluated. Using a prospective cohort design, women undergoing first-time, immediate or delayed breast reconstruction were recruited from 12 centers and 23 plastic surgeons. Complication data for expander/implant, pedicle transverse rectus abdominis musculocutaneous (TRAM) flap, and free TRAM flap procedures were evaluated 2 years after surgery in 326 patients. For each patient, the total number of complications was recorded and the complication data were dichotomized in two ways: (1) total complications and (2) major complications (those requiring reoperation, rehospitalization, or nonperioperative intravenous antibiotic treatment). The effects of procedure type, timing, radiotherapy, chemotherapy, age, smoking, and body mass index on complication rates were analyzed using logistic regression. Immediate reconstructions had significantly higher total as well as major complication rates, compared with delayed procedures (p = 0.011 and 0.005, respectively). Furthermore, higher body mass indexes were associated with significantly higher total and major complication rates (p = 0.005 and p < 0.001, respectively). No significant effects on complication rates were noted for procedure type or for the other independent variables, although there was evidence of trends for higher total and major complication rates in implant patients who received radiotherapy and a trend for higher major complication rates in TRAM flap patients who received chemotherapy. It was concluded that (1) immediate reconstructions were associated with significantly higher complication rates than delayed procedures, and (2) procedure type had no significant effect on complication rates.     

Simultaneous multiple toe transfers in hand reconstruction

Our experience with simultaneous transfer of two or more toe units to the same hand where multiple digits were missing is presented. Forty-six toes from 38 feet were transferred to reconstruct 19 hands in 19 patients. The transfers consisted of 7 combined second and third toe units and 32 single toes. Three patients had a primary and 16 patients had a secondary reconstruction. There was one complete and one partial failure. The two-point discrimination ranged from 6 mm to protective sensation. Total active movement averaged 57 degrees in the thumb and 127, 93, 71, and 68 degrees, respectively, in the fingers reconstructed at middle phalanx, proximal phalanx, metacarpophalangeal joint, and metacarpal head. Pulp-to-pulp pinch averaged 2.4 kg in patients who had thumbs reconstructed and averaged 3.0 kg in patients who had normal thumbs. There was no cold intolerance, and no significantly disabled foot occurred except one with scissoring deformity. Simultaneous multiple toe transfer in hand reconstruction is feasible without increased complications both in primary and secondary wound conditions. It is time-effective and cost-effective.     

Outcomes of brachial plexus reconstruction in 204 patients with devastating paralysis.

Thus far, devastating injuries of the adult brachial plexus have had a poor prognosis. This article presents the possible outcomes of aggressive microsurgical reconstruction in the largest series of patients in North America to date. It should change the pessimistic outlook that has surrounded these lesions. In this study, the outcomes of surgery were analyzed in relation to the type and level of injury, the age of the patient, and the denervation time; stronger donors for neurotization in relation to the various targets were delineated. The results were analyzed in 204 patients with adequate follow-up from a total of 263 patients who were operated on between 1978 and 1996. The mean age of the patients was 25.9 years, and the injuries were caused by high-velocity motor accidents involving avulsion in 55 percent of the patients. Nerve reconstruction included 577 nerve repairs (140 direct neurotizations and 437 cases of nerve grafting). Microneurolysis was performed in 89 cases. Vascularized nerve grafts were used in 120 repairs. Muscle transfers (29 pedicled and 78 free) were used to enhance function. The results were good or excellent in 75 percent of suprascapular nerve reconstructions, 40 percent of deltoid reconstructions, 48 percent of biceps reconstructions, 30 percent of triceps reconstructions, 35 percent of finger-flexion reconstructions, and 15 percent of finger-extension reconstructions. The majority of the patients had protective sensation and pain relief postoperatively.     

A new classification for the standardization of nomenclature in free flap wound closure

A profusion of terms are currently used to describe free flap wound closure. It is important to broadly standardize nomenclature when embarking on a comparison of functional outcomes between institutions. Therefore, a series of 68 "emergency" (within 24 hours) free flaps performed by a single surgeon were reviewed with respect to a total experience of 188 free tissue transfers to formulate a consistent nomenclature applicable to free flap wound closure in general. The nomenclature presented divides free flap closure into three categories: "primary free flap closure" (12 to 24 hours), "delayed primary free flap closure" (2 to 7 days), and "secondary free flap closure" (after 7 days). This system is analogous to the standard terms "primary," "delayed primary," and "secondary wound closure." It is consistent with known biologic and microbiologic principles of wound closure in general and should provide a simple basis for classifying free flap wound closure. Illustrative examples are presented to highlight the classification scheme.
