The vascular supply of the tensor fasciae latae flap and of the lateral thigh skin was studied in 10 cadavers to evaluate whether the lateral thigh skin toward the knee could be incorporated into an extended tensor fasciae latae flap. Within each cadaver, vascular injection of radiopaque material preceded flap elevation in one limb and followed flap elevation in the contralateral limb. Flaps raised after vascular injection were examined radiographically to evaluate the vascular anatomy of the lateral thigh skin independent of flap elevation. When vascular injection was made into the profunda femoris, the upper two-thirds of the flaps was better visualized than the distal third. When the injection was made into the popliteal artery, the vasculature of the distal third of the flaps was better visualized. Flaps raised before vascular injection were examined radiographically to delineate the anatomical territory of the vascular pedicle that had been injected. In these flaps, consistent cutaneous vascular supply was only seen in the skin overlying the tensor fasciae latae muscle, confirming that musculocutaneous perforators are the predominant means by which the pedicle of the tensor fasciae latae flap supplies the skin of the lateral thigh. Extended tensor fasciae latae flaps were elevated bilaterally in one cadaver, and selective methylene blue injections were made into the lateral circumflex femoral artery on one side and into the superior lateral genicular artery on the contralateral side. Methylene blue was observed in the proximal and distal thirds of the skin paddles, respectively, leaving unstained midzones. The vascular network of the lateral thigh skin could be divided into three zones. The lateral circumflex femoral artery and the third perforating branches of the profunda femoris artery perfuse the proximal and middle zones of the lateral thigh skin, respectively. The superior lateral genicular artery branch of the popliteal artery perfuses the distal zone. The middle and distal zones meet 8 to 10 cm above the knee joint, where the skin paddle of the tensor fasciae latae flap becomes unreliable. These data indicate that if the aim is to incorporate the skin over the distal thigh in an extended tensor fasciae latae flap without resorting to free-tissue transfer, then either a carefully planned delay procedure or an additional anastomosis to the superior lateral genicular artery is required.  相似文献

Anterolateral thigh flap for abdominal wall reconstruction   总被引:5,自引:0,他引:5  
The free or pedicled anterolateral thigh flap was introduced for the reconstruction of large abdominal wall defects. This flap is superior to the tensor fasciae latae musculocutaneous flap in several respects. These include the wide, reliable skin territory (which can reach the level of the knee) and the long pedicle. Therefore, a pedicled anterolateral thigh flap with reliable blood circulation can easily be positioned above the umbilicus. In addition, the free anterolateral thigh flap has greater freedom of orientation and can be used to repair larger abdominal wall defects than can the tensor fasciae latae flap. Seven patients in whom abdominal wall defects had been reconstructed with pedicled or free anterolateral thigh flaps were reviewed. Their average age was 47.1 years (range, 21 to 74 years), and the average follow-up period was 10.7 months (range, 2 to 21 months). The size of the abdominal wall defects ranged from 12 x 12 cm to 18 x 24 cm, and the size of the transferred flap ranged from 10 x 20 cm to 20 x 20 cm. Three flaps were pedicled and four were free, of which three incorporated the tensor fasciae latae flap. All flaps survived completely, and no postoperative abdominal hernias developed. Despite some variations in vascular anatomy and technical difficulties in elevating the anterolateral thigh flap, the authors conclude that the pedicled or free anterolateral thigh flap is superior to the tensor fasciae latae flap for reconstruction of large abdominal wall defects.  相似文献

An anatomic study was performed to reappraise the vasculature of the lateral intermuscular septum of the thigh and muscles associated with it using 12 preserved cadaver legs. Several possible new clinical applications of the lateral intermuscular septum and the short head of the biceps femoris were identified as follows: (1) short head of biceps femoris muscle or musculoseptal flap based on the second and/or third profunda perforating vessels, or based on the superior lateral genicular vessels, with or without the iliotibial tract and the deep fascia, and with or without the motor nerve of the short head; (2) transverse extension of the fascial portion of the tensor fasciae latae muscle or musculocutaneous flap to include the lateral intermuscular septum; (3) combination use of items 1 and 2, above; and (4) free septofascial graft using the lateral intermuscular septum and iliotibial tract.It is anticipated that the distally based short head of the biceps femoris muscle flap will be an additional option for repairing defects around the knee, and that a free short head of the biceps femoris muscle flap based on the profunda femoris perforating vessels will be useful in functional reconstruction such as reanimation of the paralyzed face. The lateral intermuscular septum can be incorporated into the short head of biceps femoris muscle flap or into the tensor fasciae latae flap, and it also can be used as a free fascial graft. Functional deficit resulting from harvesting the short head of the biceps femoris and the lateral intermuscular septum is minimal, and donor wound at the lateral lower thigh seems to be acceptable.  相似文献

The authors present their experience with a previously described but infrequently used variation of the rectus abdominis myocutaneous flap. Skin paddles angled obliquely from the line of the rectus abdominis and toward the rib cage were successfully carried on periumbilical perforators from the inferior epigastric system. Skin paddle dimensions ranged from 6.5 to 12 cm in width and from 10 to 27 cm in length in 14 consecutive patients. In six of the 14 patients, the flap was used intraabdominally to obliterate radiated pelvic defects and to close radiated vaginal defects. Five flaps were placed externally to repair radiated wounds of the perineum, thigh, and trunk, and the remaining three cases were performed as free tissue transfers. One cadaver injection study was performed to redemonstrate the preferential flow of fluid in a superior-oblique direction from periumbilical perforators. Termed the oblique rectus abdominis musculocutaneous ("ORAM") flap, this flap variation has significant advantages in terms of ease of dissection and versatility over its flap cousins the vertical rectus abdominis musculocutaneous flap and the transverse rectus abdominis musculocutaneous flap.  相似文献

In the three cases presented in this study, free tensor fasciae latae perforator flaps were used successfully for the coverage of defects in the extremities. This flap has no muscle component and is nourished by muscle perforators of the transverse branch of the lateral circumflex femoral system. The area of skin that can by nourished by these perforators is larger than 15 x 12 cm. The advantages of this flap include minimal donor-site morbidity, the preservation of motor function of the tensor fasciae latae muscle and fascia lata, the ability to thin the flap by removing excess fatty tissue, and a donor scar that can be concealed. In cases that involve transection of the perforator above the deep fascia, the operation can be completed in a very short period of time. This flap is especially suitable as a free flap for young women and children who have scars in the proximal region of the lateral thigh or groin region that were caused by split-thickness skin grafting or full-thickness skin grafting during previous operations.  相似文献

A 10-year retrospective review of 758 DIEP flaps for breast reconstruction   总被引:9,自引:0,他引:9  
This study examined 758 deep inferior epigastric perforator flaps for breast reconstruction, with respect to risk factors and associated complications. Risk factors that demonstrated significant association with any breast or abdominal complication included smoking (p = 0.0000), postreconstruction radiotherapy (p = 0.0000), and hypertension (p = 0.0370). Ninety-eight flaps (12.9 percent) developed fat necrosis. Associated risk factors were smoking (p = 0.0226) and postreconstruction radiotherapy (p = 0.0000). Interestingly, as the number of perforators increased, so did the incidence of fat necrosis. There were only 19 cases (2.5 percent) of partial flap loss and four cases (0.5 percent) of total flap loss. Patients with 45 flaps (5.9 percent) were returned to the operating room before the second-stage procedure. Patients with 29 flaps (3.8 percent) were returned to the operating room because of venous congestion. Venous congestion and any complication were observed to be statistically unrelated to the number of venous anastomoses. Overall, postoperative abdominal hernia or bulge occurred after only five reconstructions (0.7 percent). Complication rates in this large series were comparable to those in retrospective reviews of pedicle and free transverse rectus abdominis musculocutaneous flaps. Previous studies of the free transverse rectus abdominis musculocutaneous flap described breast complication rates ranging from 8 to 13 percent and abdominal complication rates ranging from 0 to 82 percent. It was noted that, with experience in microsurgical techniques and perforator selection, the deep inferior epigastric perforator flap offers distinct advantages to patients, in terms of decreased donor-site morbidity and shorter recovery periods. Mastery of this flap provides reconstructive surgeons with more extensive options for the treatment of postmastectomy patients.  相似文献

When first introduced in 1978, the tensor fasciae latae flap was used both as a free-tissue transfer and as a local rotational flap. Its use as a free flap has diminished as other more appropriate flaps for free-tissue transfer have been described. The tensor fasciae latae flap has remained, however, an instrumental flap in the coverage of anterior and posterior soft-tissue defects around the hip region. The purpose of this paper is to present a new design of the tensor fasciae latae flap in the coverage of trochanteric pressure sores. By essentially creating a VY advancement flap into the trochanteric defect with the tensor fasciae latae, one can cover the trochanteric defect with the best-vascularized portion of the flap and avoid the dog-ear deformity.  相似文献

Pedicled transverse rectus abdominis musculocutaneous (TRAM) flaps have generally been used for bilateral breast losses. The major disadvantages of this method are the total or partial loss of the rectus abdominis muscles and various resulting postoperative complications, such as abdominal bulging and lumbar pain. With the recent development of perforator flaps and supermicrosurgery with anastomosis of 0.5-mm caliber vessels, these serious complications can be overcome with a paraumbilical perforator adiposal flap, without sacrificing the rectus abdominis muscle. The breasts of a 57-year-old woman who had undergone a bilateral subcutaneous mastectomy, including silicone prostheses, were repaired simultaneously with this new method using free paraumbilical perforator adiposal flaps. This new method of breast augmentation with a vascularized adiposal flap and without any muscle component is minimally invasive; its advantages are the preservation of the rectus abdominis muscles and the short time elevation for the adiposal flap.  相似文献

The external oblique flap for reconstruction of the rectus sheath.   总被引:1,自引:0,他引:1  
Despite the availability of synthetic materials and distant fascial flaps, primary closure of ventral abdominal defects with contiguous tissues remains the preferred solution. Increased experience with such defects in the lower abdomen, particularly at the time of bilateral rectus muscle transposition, led in 1985 to the investigation of an external oblique abdominis flap for closure of the anterior rectus sheath. From October of 1985 to October of 1990, 33 patients underwent repair of bilateral lower rectus abdominis defects with the help of bilateral external oblique flaps. Each of the patients had undergone synchronous chest or breast reconstruction using a transverse rectus abdominis musculocutaneous flap including bilateral rectus muscle pedicles. Although all patients in this study had undergone double-pedicle rectus muscle procedures, not all patients having had double-pedicle rectus muscle procedures required this maneuver. External oblique flaps were performed at the time of rectus sheath repair only if fascia could not be approximated without tearing. After closure of the bilateral paramedian defect, synthetic mesh overlay was added only if the direct closure still appeared excessively tight. At the time of advancement of the external oblique muscle and fascia, the internal oblique abdominis muscle and lateral cutaneous nerve of the thigh were preserved. Of the 33 patients who underwent this procedure, 7 required the addition of mesh overlay. Thirty-two patients healed uneventfully with a remarkably solid ventral abdominal wall. One patient developed an early postoperative hernia subsequent to a major and prolonged abdominal-wall infection and abscess. Patient follow-up ranged from 1 to 36 months, with a mean of 12 months.(ABSTRACT TRUNCATED AT 250 WORDS)  相似文献

The free anterolateral thigh flap is becoming one of the most preferred options for soft-tissue reconstruction. Between June of 1996 and August of 2000, 672 anterolateral thigh flaps were used in 660 patients at Chang Gung Memorial Hospital. Four hundred eighty-four anterolateral thigh flaps were used for head and neck region recontruction in 475 patients, 58 flaps were used for upper extremity reconstruction in 58 patients, 121 flaps were used for lower extremity reconstruction in 119 patients, and nine flaps were used for trunk reconstruction in nine patients. Of the 672 flaps used in total, a majority (439) were musculocutaneous perforator flaps. Sixty-five were septocutaneous vessel flaps. Of these 504 flaps, 350 were fasciocutaneous and 154 were cutaneous flaps. Of the remaining 168 flaps, 95 were musculocutaneous flaps, 63 were chimeric flaps, and the remaining ten were composite musculocutaneous perforator flaps with the tensor fasciae latae. Total flap failure occurred in 12 patients (1.79 percent of the flaps) and partial failure occurred in 17 patients (2.53 percent of the flaps). Of the 12 flaps that failed completely, five were reconstructed with second anterolateral thigh flaps, four with pedicled flaps, one with a free radial forearm flap, one with skin grafting, and one with primary closure. Of the 17 flaps that failed partially, three were reconstructed with anterolateral thigh flaps, one with a free radial forearm flap, five with pedicled flaps, and eight with primary suture, skin grafting, and conservative methods.In this large series, a consistent anatomy of the main pedicle of the anterolateral thigh flap was observed. In cutaneous and fasciocutaneous flaps, the skin vessels (musculocutaneous perforators or septocutaneous vessels) were found and followed until they reached the main pedicle, regardless of the anatomic position. There were only six cases in this series in which no skin vessels were identified during the harvesting of cutaneous or fasciocutaneous anterolateral thigh flaps. In 87.1 percent of the cutaneous or fasciocutaneous flaps, the skin vessels were found to be musculocutaneous perforators; in 12.9 percent, they were found as septocutaneous vessels. The anterolateral thigh flap is a reliable flap that supplies a large area of skin. This flap can be harvested irrespective of whether the skin vessels are septocutaneous or musculocutaneous. It is a versatile soft-tissue flap in which thickness and volume can be adjusted for the extent of the defect, and it can replace most soft-tissue free flaps in most clinical situations.  相似文献

Primary microsurgical reconstruction is the treatment of choice for ablative defects of oral carcinoma. As a result of this trend, more and more patients with recurrent oral carcinoma who have been initially treated with surgical excision and reconstructed with free flaps are being seen. However, a second microsurgical reconstruction attempt in these cases raises questions about the flap choices, availability of recipient vessels, and effects of previous treatment modalities. Herein, 35 patients with perioral carcinoma who had two successive tumor resections and reconstruction with free flaps on each occasion are presented. A total of 75 free tissue transfers were carried out for the first and second reconstructions. After the first tumor resection, 28 radial forearm fasciocutaneous flaps, 7 fibula osteoseptocutaneous flaps, 1 iliac osteomyocutaneous flap, and 2 rectus abdominis myocutaneous flaps were used. For reconstruction after the recurrence, 17 radial forearm fasciocutaneous flaps, 13 fibula osteoseptocutaneous flaps, 3 rectus abdominis myocutaneous flaps, 2 anterolateral thigh flaps, 1 jejunum flap, and 1 tensor fasciae latae flap were used. More vascularized bone transfers were performed during the second reconstruction since the excision for the recurrence frequently required segmental mandibulectomy. The complete flap survival rate was 97.3 percent and 94.6 percent with a reexploration rate of 7.9 percent and 13.5 percent for the first and second free tissue transfers, respectively. The mean follow-up time throughout the procedures was 37.5 months. Disease-free interval between reconstructions was 20.8 months. At the time of evaluation, 54.3 percent of the patients were surviving an average of 19 months since the second reconstruction. The results suggest that free flaps represent an important option in reconstruction of recurrent perioral carcinoma cases undergoing reexcision. When used in this indication they are as safe and effective as the initial procedure.  相似文献

The purpose of the present study was to determine whether contour abnormalities of the abdomen after breast reconstruction with abdominal flaps are related to the harvest of the rectus abdominis muscle. Abdominal contour was analyzed in 155 women who had breast reconstruction with abdominal flaps; 108 women had free transverse rectus abdominis muscle (TRAM) flaps, 37 had pedicled TRAM flaps, and 10 had deep inferior epigastric perforator (DIEP) flaps. The reconstruction was unilateral in 110 women and bilateral in 45 women. Three methods of muscle-sparing were used; they are classified as preservation of the lateral muscle, preservation of the medial and lateral muscle, or preservation of the entire muscle. One of these three methods of muscle-sparing was used in 91 women (59 percent) and no muscle-sparing was used in 64 women (41 percent). Postoperative contour abnormalities occurred in 15 woman and included epigastric fullness in five, upper bulge in three, and lower bulge in 10. One woman experienced two abnormalities, one woman experienced three, and no woman developed a hernia. Of these abnormalities, 11 occurred after the free TRAM flap, seven after the pedicled TRAM flap, and none after the DIEP flap. Bilateral reconstruction resulted in 11 abnormalities in nine women, and unilateral reconstruction resulted in seven abnormalities in six women. chi2 analysis of the free and pedicled TRAM flaps demonstrates that muscle-sparing explains the observed differences in upper bulge and upper fullness (p = 0.02), with a trend toward significance for lower bulge (p = 0.06). chi2 analysis of the free TRAM and DIEP flaps does not explain the observed difference in abnormal abdominal contour. Analysis of muscle-sparing and non-muscle-sparing methods demonstrates that the observed difference between the techniques is only explained for a lower bulge after the bilateral free TRAM flap (p = 0.04).  相似文献

About 62 percent of the patients with meningomyeloceles will have essentially normal sensation in the area supplied by the lateral femoral cutaneous nerve (which is also the territory of the extended tensor fasciae latae flap), despite the fact that they may have complete anesthesia in their sitting area. In these, pressure sores can be healed and future ones prevented by transposing a sensation-bearing tensor fasciae latae flap to provide virtually normal sensibility in the sitting area.  相似文献

Secondary soft-tissue deficits may develop following a microsurgical reconstruction in the head and neck region because of inadequate planning or chronic effects of radiotherapy. Although most cases could be managed with alternative methods, free flaps might be necessary in difficult cases. Herein are described 11 cases of microsurgical head and neck reconstruction in which secondary soft-tissue deficits required transfer of another soft-tissue free flap. All patients had malignant tumors treated with surgical resection, and their defects were reconstructed with free flaps. Seven patients received either preoperative or postoperative adjunctive radiotherapy. These patients gradually developed signs and symptoms of soft-tissue deficiency in the reconstructed area, and a soft-tissue free flap transfer was required for treatment within an average of 21.5 months of their initial reconstruction. Five rectus abdominis, one rectus femoris, one latissimus dorsi, one tensor fasciae latae myocutaneous, one radial forearm, one medial arm, and one dorsalis pedis flap were used for this purpose. All flaps survived completely. The average follow-up time was 32 months. Significant improvement was achieved in all cases, and no further major surgical procedures were required. Secondary soft-tissue deficits that could not be predicted or prevented during the initial microsurgical reconstruction may be treated successfully by a subsequent free soft-tissue transfer in selected cases.  相似文献

As techniques for breast reconstruction with autologous abdominal tissue have evolved, free transverse rectus abdominis myocutaneous flaps have persevered because of their superior reliability and minimal donor-site morbidity compared with muscle-sparing techniques. Further refinements are described in this article to maximize abdominal flap perfusion and ensure primary closure of the rectus fascia. It has been well documented that incorporating both the lateral and medial perforators provides maximal perfusion to all zones of the lower abdominal transverse skin flap. However, dissection and harvest of both sets of perforators requires disruption and/or sacrifice of abdominal wall tissues. The technique presented here was designed to use both the lateral and medial row perforators, and to minimize abdominal wall disruption. Deep inferior epigastric artery medial and lateral row perforators are selected for their diameter, proximity, and transverse orientation to each other. A transverse ellipse of fascia is incised to incorporate both perforators. The fascial incision is then extended inferiorly in a T configuration to allow for adequate exposure and harvest of the vascular pedicle and/or rectus abdominis, and primary closure. Limiting perforator selection to one row of inferior epigastric arteries diminishes perfusion to the abdominal flap. Furthermore, perforator and inferior epigastric artery dissection often results in fascial defects that are not amenable to primary closure. However, maximal abdominal flap perfusion and minimal donor-site morbidity can be achieved with the transverse dual-perforator fascia-sparing free transverse rectus abdominis myocutaneous flap technique and can be performed in most patients.  相似文献

Reconstruction of composite defects of the mandible is a challenging problem. Although the use of an osteocutaneous free flap, alone or in combination with another soft-tissue free flap, is generally accepted to be optimal, the bony reconstruction is sometimes undervalued, especially when the cancer is advanced. In such situations, reconstruction is often performed with a reconstruction plate covered with a soft-tissue free flap. Between January of 1997 and July of 2000, 80 patients with composite or extensive composite oromandibular defects underwent treatment with a reconstruction plate and a soft-tissue free flap. All of the patients were male, and the ages of the patients at the time of treatment ranged from 32 to 78 years (mean, 51 years). Tumors were classified as stage IV in 56 patients (70 percent), whereas the remaining 24 patients (30 percent) had recurrent carcinomas. The titanium mandibular reconstruction system manufactured by Stryker (Freiburg, Germany) was used to bridge the mandibular defects. The soft-tissue free flaps used for wound and plate coverage were as follows: anterolateral thigh flap (n = 75), radial forearm flap (n = 3), transverse rectus abdominis myocutaneous flap (n = 1), and tensor fasciae latae flap (n = 1). Five patients with recurrent carcinomas and 10 with stage IV carcinomas (18.75 percent) died 2 to 6 months after the operation and were excluded from the study. The remaining 65 patients were monitored for an average follow-up period of 22 months (range, 6 to 40 months). During that period, one or more complications occurred for 45 patients (69.2 percent). Plate exposure was the most common complication and was observed for 30 patients (46.15 percent). Twenty of the 65 patients (30.8 percent) required secondary salvage reconstruction with a fibula osteoseptocutaneous flap. The decision to perform a secondary salvage procedure was based on the general health of the patient, the extent of local disease, and the severity of the complications. Patients underwent salvage operations after an average of 11.5 months (range, 6 to 26 months). The major reasons for the second operation were as follows: reconstruction plate exposure (n = 12), soft-tissue deficiency and mandibular contour deformation of the lateral face (n = 7), intraoral contracture and lack of a gingivobuccal sulcus (n = 6), trismus (n = 4), and osteoradionecrosis of the mandible (n = 2). The total flap survival rate was 90 percent (18 of 20 free flaps). In two cases, the skin paddles of the fibula osteoseptocutaneous flaps exhibited partial failure and were revised with pedicled pectoralis major and deltopectoral flaps. The reconstruction plate and free soft-tissue flap procedure for the reconstruction of composite defects of the oromandibular region has many late complications, which eventually necessitate reconstruction of the mandible with an osteocutaneous free flap.  相似文献

The advantages of breast reconstruction using the deep inferior epigastric perforator (DIEP) flap and the muscle-sparing free transverse rectus abdominis musculocutaneous (TRAM) flap (MS-2) are well recognized. Both techniques optimize abdominal function by maintaining the vascularity, innervation, and continuity of the rectus abdominis muscle. The purpose of this study was to compare these two methods of breast reconstruction and determine whether there is a difference in outcome. The study considered 177 women who have had breast reconstruction using muscle-sparing flaps over a 4-year period. This includes 89 women who had an MS-2 free TRAM flap procedure, of which 65 were unilateral and 24 were bilateral, and 88 women who had a DIEP flap procedure, of which 66 were unilateral and 22 were bilateral. The total number of flaps was 223. Mean follow-up was 23 months (range, 3 to 49 months). For all MS-2 free TRAM flaps (n = 113), outcome included fat necrosis in eight (7.1 percent), venous congestion in three (2.7 percent), and total necrosis in two (1.8 percent). For the women who had an MS-2 free TRAM flap, an abdominal bulge occurred in three women (4.6 percent) after unilateral reconstruction and in five women (21 percent) after bilateral reconstruction. The ability to perform sit-ups was noted in 63 women (97 percent) after unilateral reconstruction and 20 women (83 percent) after bilateral reconstruction. For all DIEP flaps (n = 110), outcome included fat necrosis in seven (6.4 percent), venous congestion in five (4.5 percent), and total necrosis in three (2.7 percent) patients. For the women who had DIEP flap reconstruction, an abdominal bulge occurred in one woman (1.5 percent) after unilateral reconstruction and in one woman (4.5 percent) after bilateral reconstruction. The ability to perform sit-ups was noted in all women after unilateral reconstruction and in 21 women (95 percent) after bilateral reconstruction. These results demonstrate that there are no significant differences in fat necrosis, venous congestion, or flap necrosis after DIEP or MS-2 free TRAM flap reconstruction. The percentage of women who are able to perform sit-ups and the percentage of women who did not develop a postoperative abdominal bulge is increased after DIEP flap reconstruction; however, this difference is not statistically significant.  相似文献

A surgical procedure with the transverse rectus abdominis myocutaneous (TRAM) flap for breast reconstruction is presented using parameters from the opposite normal breast to achieve a better cone shape in the new breast to project the nipple-areola complex. This cone projection is obtained through a vertical plication of both skin/fat halves of the TRAM flap and with two supraumbilical fat flaps to avoid cone collapse. The infraclavicular and axillary regions are filled with a de-epithelialized "fish-fin" cutaneous-fat or fat-only flap, which is placed as a lateral TRAM extension. The de-epithelialized lateral extremity of the TRAM flap folded over itself gives a mound shape to the lateral aspect of the new breast, and the inverted umbilical stalk attached to the TRAM flap imitates a nipple. This procedure is based on six breast reconstructions with a 2-year follow-up. The procedure is a simple, safe, and versatile way to mimic the opposite breast. It is mostly indicated for thin patients who have small to moderate breasts without ptosis or hypertrophy who refuse breast implants or request a mastopexy or reduction mammaplasty on the opposite normal breast during the same procedure.  相似文献

The transverse rectus abdominis musculocutaneous (TRAM) flap is widely used in autologous breast reconstructions. In transferring tissue as a pedicled or free flap, alterations in sensibility are unavoidable. This study evaluated somatosensory function in the reconstructed breast at least 2 years after pedicled or free TRAM flap surgery. Thirteen patients who had a pedicled TRAM flap and 13 patients who had a free TRAM flap participated in the study. The patients completed a questionnaire regarding subjective sensibility and their general opinion of the reconstructed breast. Somatosensory examinations to study the sensations of touch, warmth, cold, and pain were performed using nonquantitative and quantitative techniques. An age-matched control group of eight women who had never had breast surgery was also examined because the majority of the women who had breast reconstruction also had a mammaplasty performed on the contralateral breast, which disqualified it as a control. The majority of the patients reported that the reconstructed breast felt like a real breast. However, sensibility to touch, warmth, cold, and pain was decreased in the study groups compared with the control group. No clinically significant differences existed in sensibility between the pedicled and free TRAM flap groups.  相似文献
