Quality of life, patients' satisfaction, and aesthetic outcome after pedicled or free TRAM flap breast surgery

Breast reconstructions after breast cancer surgery are primarily performed to improve patients' quality of life. This study was performed to investigate patients' satisfaction with breast reconstruction and quality of life after pedicled or free transverse rectus abdominis musculocutaneous (TRAM) flap surgery and to evaluate the aesthetic result of the breast reconstruction both objectively and subjectively.Sixty-three patients (36 with pedicled flaps and 27 with free TRAM flaps) answered two questionnaires; of this group, 53 (27 with pedicled flaps and 26 with free TRAM flaps) participated in an aesthetic evaluation. The questionnaires consisted of two parts: one study-specific part concerning satisfaction with the result of the breast reconstruction, the other a standardized health-related quality of life part, the Short Form-36 questionnaire. The aesthetic examination consisted of an objective part in which various distances on the reconstructed and contralateral breast were measured. The volumes of the breasts were measured using a thermoplastic cast system. The softness of the breasts was assessed using applanation tonometry. A panel consisting of three plastic surgeons looked at four standardized photographs of each patient and evaluated the aesthetic outcome subjectively. The panel evaluated the breast reconstruction on 10 subscales. No statistically significant difference between the surgical groups was seen regarding the patients' satisfaction with the reconstruction. In the patients' self-assessment of the cosmetic outcome, the degree of symmetry was assessed higher in the free TRAM flap group. The health-related quality of life Short Form-36 questionnaire revealed no difference between the pedicled and free flap groups. Compared with a reference population, the breast-reconstructed group felt more tired and "worn out," less peaceful, more unhappy, and more restless. The free flap group reached a higher degree of symmetry in the objective evaluation and received generally higher scores from the three-member panel, compared with the pedicled TRAM flap group. A strong correlation between the patients' and the panel's evaluations of the cosmetic outcome was seen; generally, the panel's evaluation of the cosmetic result of the breast correlated with the satisfaction of the patients.     

Optimizing autologous breast reconstruction in thin patients

Breast reconstruction with a transverse rectus abdominis myocutaneous (TRAM) flap plus an implant has been proposed as an option for women with a thin body habitus who do not have sufficient abdominal tissue to permit reconstruction with a TRAM flap alone. The standard autologous tissue reconstructive procedure in these women is a combined latissimus dorsi myocutaneous flap and breast implant. We reviewed our experience performing TRAM flap/implant and latissimus dorsi flap/implant breast reconstruction to compare complication rates and aesthetic outcomes between these two types of reconstruction. Between 1992 and 1999, 88 breasts were reconstructed at our institution using an autologous tissue flap combined with a breast implant (44 with a TRAM flap/implant and 44 with a latissimus dorsi flap/implant). Recipient-site and donor-site complications for the two procedures were compared using Fisher's exact test; a panel of unbiased, blinded judges compared the aesthetic outcomes. The recipient-site complication rate was lower for the TRAM flap/implant group than for the latissimus dorsi flap/implant group (18 percent versus 34 percent, p = 0.09). Most recipient-site complications in the TRAM flap/implant group were related to fluid collection around the implant. In the TRAM flap/implant group, complications occurred in 37 percent of the reconstructions that had immediate implant placement and in none of the reconstructions with delayed implant placement (p = 0.01). In the TRAM flap/implant reconstructions with immediate implant placement, the recipient-site complication rate was 50 percent when implants were completely filled with saline, but no complications occurred with incompletely filled, postoperatively adjustable implants (p = 0.03). No microvascular complications occurred with immediate placement of breast implants under TRAM flaps. Donor-site complications included a hematoma, a seroma, and an umbilical necrosis in the TRAM flap/implant group and six cases of seroma formation in the latissimus dorsi flap/implant group. The comparison of aesthetic outcome was statistically significant for the TRAM flap/implant group, which had a higher overall mean score than the latissimus dorsi flap/implant group did (3.29 versus 2.85, p = 0.01). The results of this study suggest that the TRAM flap/implant breast reconstruction should be considered as an alternative to the latissimus dorsi flap/implant breast reconstruction in women with a thin body habitus.     

A comparison of outcomes using three different methods of breast reconstruction.

In a review of 325 postmastectomy breast reconstructions, the aesthetic quality of the result and the risk of unsuccessful outcome were compared for three techniques: tissue expansion (105 breasts), latissimus dorsi myocutaneous flap (47 breasts), and TRAM flap (173 breasts). The aesthetic successes achievable with the three methods were similar, and some excellent results were achieved with each of them. The failure rate after tissue expansion (21 percent) was significantly higher than those observed with the TRAM (3 percent) and latissimus (9 percent) flaps. Tissue expansion also was not as aesthetically successful as other techniques in obese patients. For immediate breast reconstruction, the TRAM flap was the most aesthetically successful technique. Although tissue expansion has advantages and may be the best choice for some patients, methods that used autogenous tissue provided more consistent success.     

Breast reconstruction with latissimus dorsi flap: improved aesthetic results after transection of its humeral insertion.

Does transecting the tendinous insertion of the latissimus dorsi on the humerus improve aesthetic results and avoid the displeasing bulge in the armpit that sometimes occurs when the latissimus dorsi is used for breast reconstruction? In a prospective study, 60 patients who were having breast cancer surgery and simultaneous breast reconstruction using the latissimus dorsi flap were randomized for cutting (n = 29) or leaving intact (n = 31) the tendinous muscle insertion on the humerus. The cosmetic outcome was evaluated by patients and surgeons 6 to 12 months postoperatively. Patients reported good cosmetic results in 29 of 31 cases with the humeral insertion left intact and in 26 of 29 cases when the tendon was cut (p = 0.59), as compared with 21 of 31 cases versus 25 of 29 cases (p = 0.091), according to the surgeon's evaluation. A lateral bulge was more frequently observed by the surgeons in the group with intact insertion (10 of 31 patients), as compared with the group with a transected humeral insertion (2 of 29 patients). Discomfort caused by this bulge was reported by 19 of 31 patients with intact insertion, but only 3 of 29 patients with the tendon cut (p < 0.0001). The additional transection of the tendon was not associated with any complications. The additional transection of the tendinous humeral insertion of the latissimus dorsi muscle improves aesthetic results and avoids a displeasing bulge in the axilla when the latissimus dorsi flap is used for breast reconstruction.     

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 cancer after augmentation mammaplasty: treatment by skin-sparing mastectomy and immediate reconstruction

Breast conservation has been associated with poor cosmetic outcome when used to treat breast cancer in patients who have undergone prior augmentation mammaplasty. Radiation therapy of the augmented breast can increase breast fibrosis and capsular contraction. Skin-sparing mastectomy and immediate reconstruction are examined as an alternative treatment.Six patients with prior breast augmentation were treated for breast cancer by skin-sparing mastectomy and immediate reconstruction. One patient underwent a contralateral prophylactic skin-sparing mastectomy. Silicone gel implants had been placed in the submuscular location in five patients and in the subglandular position in one patient a mean of 10.2 years (range, 6 to 20 years) before breast cancer diagnosis. The mean patient age was 41.3 years (range, 33 to 56 years). Four independent judges reviewed postoperative photographs to grade the aesthetic results in comparison with the opposite native or reconstructed breast.The American Joint Committee on Cancer staging was stage 0 in one patient, stage I for four patients, and stage II for one patient. Five of the six patients presented with a palpable breast mass. Latissimus dorsi flap reconstruction was performed in four patients (bilaterally in one) and a transverse rectus abdominis muscle (TRAM) flap was used in two patients. Three patients were treated by skin-sparing mastectomy with preservation of the breast implant (two patients with latissimus flaps, and one patient with a TRAM flap). The tumor location necessitated the removal of implants in two patients (one patient with a latissimus flap and one with a TRAM. A saline implant was placed under the latissimus flap after gel implant removal. The patient who underwent bilateral skin-sparing mastectomies desired explantation and placement of saline implants. No remedial surgery was performed on the opposite breast to achieve symmetry. Complications occurred in two patients at the latissimus dorsi donor site (seroma in one patient, and seroma and infection in one). Five patients underwent complete nipple reconstructions. The mean duration of follow-up was 33.6 months (range, 15.5 to 70.3 months), and there were no recurrences of breast cancer. The aesthetic results were judged to be good to excellent in all cases.Skin-sparing mastectomy and immediate reconstruction can be used in patients with prior breast augmentation, with good to excellent cosmetic results. Depending on the tumor and implant location, the implant may be preserved without compromising local control.     

The lateral thoracodorsal flap in breast reconstruction

A fasciocutaneous transposition flap, the lateral thoracodorsal flap, has been used in 114 cases of breast reconstruction. This flap is raised from the lateral and dorsal aspects of the thoracic wall at the level of the submammary crease, and the size may be varied from 12 to 22 cm in length and 6 to 12 cm in width. The lateral thoracodorsal flap is used with an implant and forms the lateral part of the reconstructed breast. A natural ptotic breast shape is achieved in a single-stage procedure. Complications such as partial necrosis and infection have occurred in 3.5 and 2.5 percent of cases, respectively. The procedure is simple and has at our unit largely replaced the use of the latissimus dorsi musculocutaneous flap in extensive postmastectomy defects. In less disfiguring defects, the lateral thoracodorsal flap has taken the place of direct implantation because the reconstructed breast obtains a more pleasing shape by augmentation of the lower lateral pole.     

Muscle-sparing latissimus dorsi myocutaneous flap with maintenance of muscle innervation,function, and aesthetic appearance of the donor site

In this report, the authors describe the application of a muscle-sparing technique to harvest a myocutaneous latissimus dorsi muscle flap, including only a tiny lateral muscle segment but carrying a large skin paddle, with the advantage of leaving intact innervation and function of the remaining latissimus dorsi muscle. According to the experiences and complications associated with the pure thoracodorsal artery perforator harvest at the authors' institution, the necessity of increasing the reliability of the vascular pedicle demands that a small muscle strip be left embedding the perforator vessels attached to the skin paddle. This procedure was applied in eight cases with only one minor complication, which was a distal flap tip necrosis in the largest flap used. The muscle function and aesthetic contour of the posterior axillary fold were preserved in every case. Harvesting a large skin paddle flap that is carried by a diminutive longitudinal segment of latissimus dorsi muscle circumvents thoracodorsal nerve damage and maintains muscle function. In contrast to a thoracodorsal artery perforator flap without muscle, the harvesting of which is a delicate procedure, this procedure is regarded as easier and safer.     

The early management of flap necrosis in breast reconstruction

Flap necrosis is a potential complication of any type of breast reconstruction. Of 302 breast reconstructions performed by the author at the University of Texas M.D. Anderson Cancer Center, some degree of flap necrosis occurred in 59 (19.5 percent). Small areas of flap necrosis can be managed with simple observation, but secondary healing may not be complete for months. Early and aggressive excision of the ischemic tissue with immediate primary closure often can achieve rapid primary healing. In addition, early revision and reshaping of the breast may, in selected patients, permit achievement of a significantly better final result. This is true not only for TRAM and latissimus dorsi flaps, but also for the mastectomy flap necrosis sometimes encountered in immediate reconstruction with simple implants or tissue expanders.     

The "reduced" latissimus dorsi musculocutaneous flap

This report introduces a new device among latissimus dorsi flaps: the "reduced" latissimus dorsi musculocutaneous flap. This flap consists of a proximal musculocutaneous unit and a distal, thin fasciocutaneous unit (the "reduced" portion). The former unit carries a reliable blood supply from the thoracodorsal artery and is able to cover deeper recipient defects, while the latter provides a well-contoured reconstruction of the defect. If needed, an extended portion and/or a thin cutaneous flap can be carried along with the flap according to the defect. In our clinic, we have so far used four pedicled and one free reduced latissimus dorsi musculocutaneous flap in the repair of a variety of defects. All flaps survived, and satisfactory contour of the recipient site was achieved in each case. These clinical experiences clarify that a reduced portion 10 cm in length can be safely carried, and it is suggested that survival of this flap does not depend on its width-to-length ratio.     

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.     

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.     

Donor site sequelae after autologous breast reconstruction with an extended latissimus dorsi flap

The indications for autologous reconstruction are increasing. The standard procedure is the transverse rectus abdominis muscle flap; however, this flap has contraindications and drawbacks. The latissimus dorsi muscle flap is simple and reliable. Hokin et al. demonstrated in 1983 that this flap can be extended and used for breast reconstruction without an implant. Since then, it has been widely studied in this setting and is known to provide good aesthetic results. Dorsal sequelae, conversely, were not appraised. The aim of this study was to assess objective and subjective dorsal sequelae after the harvest of an extended flap. Forty-three consecutive patients who had had breast reconstruction with an autologous latissimus dorsi flap were assessed by a surgeon and a physiotherapist for muscular strength and shoulder mobility. Patient opinion was studied through a questionnaire. Mean delay between the operation and the evaluation was 19 months. Early complications, mainly dorsal seromas, were frequent after the harvest of an extended flap (72 percent). There was no late morbidity and, especially, no flap loss or partial necrosis. As for functional results, 37 percent of the patients had complete adjustment and 70 to 87 percent demonstrated no change in shoulder strength. Sixty percent of the patients experienced no limitation in everyday life, and 90 percent said they would undergo this procedure again. The authors show that dorsal sequelae after an extended latissimus dorsi flap are minimal and that this technique compares favorably with the transverse rectus abdominis muscle flap.     

Sensitivity of breasts reconstructed with the autologous latissimus dorsi flap

The purpose of this study was to measure, both objectively and subjectively, the sensitivity of breasts reconstructed with the autologous latissimus dorsi flap and to compare these results with those of other reconstruction techniques, especially the transverse rectus abdominis myocutaneous flap. The study population included 50 patients with autologous latissimus dorsi flap breast reconstruction; these patients had an average age of 51 years and an average follow-up of 27 months. Patients answered a seven-item questionnaire that attempted to define the sensitivity of the reconstructed and opposite breasts. This sensitivity was then measured objectively using standard techniques for heat, cold, and tactile sensations. After statistical analysis, these results were compared with those published for other reconstruction techniques. Overall results were comparable or superior to those published for other techniques for autologous breast reconstruction. A total of 56 percent of patients had fine or very fine sensitivity, but 70 percent deemed this sensitivity to be less than that of the opposite breast. A total of 94 percent of patients perceived the reconstructed breast as integral to their body image. The superior medial part of the breast had the greatest sensitivity, both objectively and subjectively. Autologous latissimus dorsi breast reconstruction, a good technique with excellent aesthetic results, affords satisfactory sensitivity. This is yet another advantage of the technique.     

Continued twitching of the latissimus dorsi miniflap after breast conservation therapy: a case report

We report a case of continued twitching of the latissimus dorsi muscle following breast conservation therapy, along with immediate reconstruction with a latissimus dorsi miniflap, which continued despite several attempts at control including BTX-A percutaneous local injection, and was finally cured by delayed division of the thoracodorsal nerve via a small well-tolerated axillary incision.     

Reconstructive management of contralateral breast cancer in patients who previously underwent unilateral breast reconstruction

When a patient who has had unilateral breast reconstruction presents with a new cancer on the opposite side, the reconstructive management of the second breast can be unclear. This study was performed to determine whether reconstruction of the second breast is oncologically reasonable and to evaluate the reconstructive options available to these patients.Patients who had mastectomy with unilateral breast reconstruction between 1988 and 1994 and who had a minimal follow-up of 5 years from the initial breast cancer were reviewed. Of 469 patients reviewed, 18 patients (4 percent) were identified who developed contralateral breast cancer. Mean age at the initial breast cancer presentation was 43 years (range, 26 to 57 years), and mean age at presentation with contralateral breast cancer was 48 years (range, 36 to 67). The mean interval between the initial and contralateral breast cancer presentations was 5 years (range, 1 to 10 years). Mean follow-up from the time of contralateral breast cancer was 5 years (range, 1 to 9 years). In most cases, contralateral breast cancer presented at an early stage (13 of 18 patients; 72 percent), and a shift to an earlier stage at presentation of the contralateral cancer was evident compared with the initial breast cancer. Of the 18 patients who developed contralateral breast cancer, 16 (89 percent) had no evidence of disease, one was alive with disease, and one died. Reconstructive management after the initial mastectomy included 16 transverse rectus abdominis myocutaneous flaps (seven free and nine pedicled), one latissimus dorsi myocutaneous flap with implant, and one superior gluteal free flap. Surgical management of the second breast after contralateral breast cancer included breast conservation in two patients, mastectomy without reconstruction in four, and mastectomy with reconstruction in 12. Reconstruction of the second breast included one free transverse rectus abdominis myocutaneous flap, three extended latissimus dorsi flaps, two latissimus dorsi myocutaneous flaps with implants, three implants alone, two Rubens flaps, and one superior gluteal free flap. No major complications were noted after the reconstruction of the second breast. The best symmetry was obtained when similar methods and tissues were used on both sides.The incidence of contralateral breast cancer after mastectomy and unilateral breast reconstruction is low. In most cases, contralateral breast cancer presents at an earlier stage compared with the initial breast cancer, and the prognosis is good. In patients who develop a contralateral breast cancer after mastectomy and unilateral breast reconstruction, the reconstruction of the second breast after mastectomy is oncologically reasonable and should be offered to provide optimal breast symmetry and a better quality of life. The best result is obtained when similar methods and tissues are used on both sides.     

Immediate free TRAM reconstruction in lumpectomy and radiation failure patients

Local recurrence after lumpectomy and radiation therapy indicates failed breast conservation surgery. These patients often proceed to mastectomy and are candidates for autogenous breast reconstruction. Free transverse rectus abdominus muscle (TRAM) reconstruction in these patients is complicated by repeated axillary dissection and the use of irradiated tissue. Complication rates for pedicled TRAMs have been reported at 33 percent when used in irradiated tissue beds. We report our results using the free TRAM for breast reconstruction after lumpectomy and radiation failure. All patients within this study developed a local recurrence after lumpectomy and radiation therapy. All patients had undergone axillary dissection for staging at the time of their lumpectomy. Patient records were reviewed for patient age, total radiation dose, associated risk factors for TRAM failure, operative time, donor vessels used for anastomosis, status of the native thoracodorsal vessels at the time of surgery, and postoperative complications. Over a 7-year period, 16 TRAM patients had undergone previous breast conservation surgery. Of these 16 patients, 14 underwent reconstruction with a planned free TRAM after simple mastectomy. Average operating room time was 7 hours. There were no partial or total flap losses. Complications were seen in 14 percent of the overall group. Overall, we found that the free TRAM provided an excellent aesthetic result with a lower complication rate than previously reported for pedicled TRAM flaps in irradiated beds. The thoracodorsal vessels provided an adequate donor vessel in 93 percent of the cases. The free TRAM provides a superior alternative in immediate reconstruction in patients who have failed breast conservative surgery.     

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.     

Chest-wall reconstruction by contralateral latissimus dorsi musculocutaneous flap

Reconstruction of chest wall and axilla are performed in 11 patients using a contralateral latissimus dorsi musculocutaneous flap. The entire lattisimus dorsi muscle, including the fascial portion, safely carried an island of skin from the area of the lumbodorsal fascia to the contralateral axilla. The flap was transposed to the defect through a tunnel between the pectoralis major and minor muscles. Most patients who needed reconstruction of the chest wall and axilla had compromised ipsilateral vasculature that prohibited its use in a pedicled flap but had an intact contralateral chest wall, axilla, and thoracodorsal vessels. Therefore, this procedure was performed easily in comparison with a free flap or pedicled omental flap. This is a new, valuable application for the versatile latissimus dorsi musculocutaneous flap.
