Skin-sparing mastectomy and immediate breast reconstruction: a prospective cohort study for the treatment of advanced stages of breast carcinoma

Background Recent published series demonstrate the safety and effectiveness of skin-sparing mastectomy (SSM) with immediate reconstruction for the treatment of early-stage breast carcinoma. Although several reports have retrospectively evaluated outcomes after breast reconstruction for locally advanced disease (stages IIB and III), no study has specifically considered immediate breast reconstruction after SSM for locally advanced disease. Methods From 1996 to 1998, 67 consecutive patients with breast carcinoma underwent SSM with immediate reconstruction and were prospectively observed. From this group of patients, those with locally advanced disease (stage IIB, n=12; stage III, n=13) were analyzed separately. Tumor characteristics, adjuvant therapy, type of reconstruction, operative time, complications, hospital stay, and incidence of local recurrence and distant metastasis were noted. Results Breast reconstruction consisted of a transverse rectus abdominis myocutaneous flap (n=22) or a latissimus flap plus an implant (n=4). The median operative time was 5.5 hours; the average hospital stay was 5.2 days. Complications required reoperation in three patients (12%): partial skin flap necrosis in two and partial abdominal skin necrosis in one. Surgery on the opposite breast for symmetry was required in one patient (4%). Postoperative adjuvant therapy was not significantly delayed (median interval, 32 days). With a median length of follow-up of 49.2 months (range, 33–64 months), local recurrence was present in only one patient (4%), with successful local salvage treatment, and distant metastasis was present in four patients (16%). Conclusions SSM with immediate reconstruction seems safe and effective and has a low morbidity for patients with advanced stages of breast carcinoma. Local recurrence rates and the incidence of distant metastasis are not increased compared with those of patients who have had modified radical mastectomies without reconstruction.     

Comparison of aesthetic breast reconstruction after skin-sparing or conventional mastectomy in patients receiving preoperative radiation therapy

Many options exist for the surgical treatment of breast cancer in terms of tumor extirpation and reconstruction. Skin-sparing mastectomy (SSM) with immediate reconstruction offers patients a superior result, but this can be jeopardized by preoperative radiotherapy. We compared the outcomes of reconstruction after SSM or conventional mastectomy (CM) in the previously irradiated breast.We evaluated 41 patients over an 8-year period, who were divided into 3 categories: preoperative radiotherapy prior to SSM (n = 8), CM after preoperative radiation therapy (n = 9), and no chest wall irradiation prior to SSM (n = 20). The first group demonstrated significantly higher frequency of native flap compromise and capsular contracture formation than the other 2 groups.SSM with TRAM or latissimus with implant reconstruction is an esthetically optimal option for the treatment of patients without previous radiotherapy. However, for patients with preoperative chest wall radiation, TRAM flap reconstruction was superior to latissimus flap with implant after SSM.     

Autologous breast reconstruction: the Vanderbilt experience (1998 to 2005) of independent predictors of displeasing outcomes

BACKGROUND: Optimal surgical outcomes are dependent on an appreciation of comorbid conditions that may handicap results. The purpose of this retrospective analysis was to delineate risk factors for complications after autologous breast reconstruction. STUDY DESIGN: An institutional database was constructed of patients who underwent autologous breast reconstruction from 1998 to 2005. Variables captured included age, diabetes and smoking status, prereconstruction radiation therapy, concomitant breast resection, preoperative albumin, flap type, and body mass index (BMI; based on World Health Organization classifications: BMI>25, overweight; >30, obese). The primary outcome was noninfectious wound complications (NIWC), a novel classification based on the extent of tissue derangement and need for operative intervention. Secondary outcomes were wound infection, hematoma, hernia, and fat necrosis. Statistical analysis was performed using chi-square tests and multiple logistic regression. RESULTS: The analysis included 200 flaps (transverse rectus abdominis myocutaneous [TRAM]=171; latissimus dorsi=29) in 180 patients. There were 19 infections (9.5%), 3 total flap losses (1.5%), 14 hematomas (7%), and 11 donor-site hernias (6%). The incidences of fat necrosis and any NIWC were 18% and 36%, respectively. Mean followup was 13.1 months (range 1.1 to 51.7 months). Multiple logistic regression demonstrated that obesity (BMI>30) is a statistically significant independent risk factor for any NIWC (hazards ratio=6.58; 95% CI, 2.85 to 15.18; p < 0.01) and for NIWC requiring operative treatment (NIWC>or=3; hazard ratio=6.23; 95% CI 2.15 to 18.05; p < 0.01). Increased BMI predicts NIWC, NIWC requiring operative intervention, and wound infection (p < 0.01). CONCLUSIONS: These data suggest that obesity is a strong predictor of simple and complex NIWC and of wound infection after autologous breast reconstruction. Obese patients should be counseled about their significantly increased risk of experiencing these unwanted outcomes.     

Complications associated with breast reconstruction using a perforator flap compared with a free TRAM flap

This study evaluated the recipient and donor site complications associated with breast reconstruction using a deep inferior epigastric artery perforator flap (DIEAP) flap compared with a free TRAM flap. The charts of 108 patients who underwent breast reconstruction using these techniques were reviewed. There were 130 flaps. Patients with free TRAM flaps had a significantly longer hospital stay (P=0.003). There were significantly more cases of fat necrosis in the unilateral DIEAP flaps (P=0.001). In patients who were overweight or obese (body mass index >25 kg/m), there were significantly more breast complications (P=0.006). There were more cases of abdominal flap necrosis at the donor site in smokers (P = 0.018) and the diabetic patients (P=0.013). This study suggests that postoperative complications are related to patient comorbidities, and personal factors and should be considered when selecting the most appropriate reconstructive option.     

Factors predicting free flap complications in head and neck reconstruction.

In this retrospective study, all free flap transfers used for reconstruction following ablation of head and neck tumors in University Medical Centre Ljubljana between the years 1989 and 1999 were analysed. The data taken from the patients' charts covered the demographic profile, the tumor and free flap details (44 variables for each patient). Logistic regression model was used to identify factors associated with free flap failure and complications. One hundred and sixty-two patients with head and neck tumors underwent microsurgical reconstruction. One hundred and ninety-four free flaps were performed with an overall success rate of 85%. Two significant predictors of free flap complication were identified: diabetes and salvage free flap transfer. Patients with diabetes were five times more likely to develop complications associated with free flaps (p = 0.02). Free flap complications were four times more likely to develop after salvage free flap transfer (p = 0.04). In addition, two significant factors predicting free flap failure were identified: salvage free flap transfer (p = 0.019) and use of interposition vein grafts (p = 0.032). After this study we changed our strategy of free flap selection and preoperative evaluation of the patients with head and neck tumors requiring free tissue transfer. Between January 2000 and January 2005 we performed additional 105 free flaps for head and neck reconstruction after tumor resection in 101 patients and our success rate improved to 94.3%.     

Tips and tricks for DIEP flap breast reconstruction in patients with previous abdominal scar

The aim of this study was to analyze outcomes of patients who had prior abdominal operations and underwent DIEP flap breast reconstruction and to describe technical strategies to insure well‐vascularized flap‐harvest minimizing abdominal donor‐site complications. All patients who underwent DIEP flap breast reconstruction between 2004 and 2014 were reviewed and divided into a control group (CG) and a scar group (SG). Patient demographics, operative details, flap and donor‐site complications were analyzed and compared. For all of the scars, DIEP flap design was not modified, but a standardized approach was developed according to the type and location of the scar, available vascular pedicle, perforator locations, and the required flap tissue for breast reconstruction. Two hundred and eighty patients underwent 292 flaps in CG and 107 underwent 111 flaps in SG. Pfannenstiel, McBurney, laparoscopic, midline and subcostal were the most common previous incisions. There were no significant differences between groups regarding demographics, flap and mastectomy weight, active smoking, or radiation status (P > 0.05). No significant differences were observed in DIEP flap loss (P = 0.909), partial flap loss (P=0.799), or fat necrosis (P=0.871) and in the rate of abdominal donor‐site complications between groups (P > 0.05). SG had a significantly higher mean operative time than CG (P=0.034). Medial raw was a negative risk‐factor for flap complications, while BMI (>25.1 kg/m²) and smoking‐history were significant predictors for donor‐site complications. With careful preoperative planning and appropriate technical strategies, successfully DIEP flap breast reconstruction can be performed without increased flap and donor‐site complications in patients with preexisting abdominal scars. © 2015 Wiley Periodicals, Inc.

A critical review of perioperative complications in 175 free deep inferior epigastric perforator flap breast reconstructions

BACKGROUND: The purpose of this study was to critically evaluate the perioperative complications for deep inferior epigastric perforator (DIEP) flap breast reconstruction. METHODS: From February 2002 until February 2006, 175 consecutive abdominal free tissue breast reconstructions were performed in 131 patients. Perioperative risk factors and complications were evaluated for the entire group. Data analysis was performed to compare subsequent chronologic groups for a learning curve effect. RESULTS: In 159 cases (90.9%) a DIEP flap could be raised. In 13 cases (7.4%), a mini-TRAM flap and in 3 cases (1.7%) a regular free TRAM flap was harvested. A learning curve was found showing a risk for flap complications in the first 30 DIEP flaps of 40% and in flaps 31 to 175 of 13.8% (P < 0.012). Microsurgical revision rate was 4% (n = 7), with a total flap failure rate of 0.6% (n = 1). Partial flap failure rate was 8.6% (n = 15), which was solved by debridement, medial advancement, and direct closure in 6.8% (n = 12) and latissimus dorsi flap transposition in 1.8% (n = 3). Multivariate analysis showed no significant influence of risk factors on development of postoperative flap complications. CONCLUSION: DIEP flap breast reconstruction is an excellent method, with limited donor-site morbidity. A definite learning curve was reflected in a larger number of flap complications in the beginning of our series.     

Outcomes of immediate vertical rectus abdominis myocutaneous flap reconstruction for irradiated abdominoperineal resection defects

BACKGROUND: Perineal wound complications after chemoradiotherapy and abdominoperineal resection (APR) for anorectal cancer occur in up to 60% of patients, including perineal abscess and wound dehiscence. Vertical rectus abdominis myocutaneous (VRAM) flaps have been used in an attempt to reduce these complications by obliterating the noncollapsible dead space with vascularized tissue and closing the perineal skin defect with nonirradiated flap skin. Many surgeons are reluctant to use VRAM flaps unless primary closure is not possible. STUDY DESIGN: All patients who underwent chemoradiotherapy and APR during a 12-year period at the University of Texas MD Anderson Cancer Center were retrospectively reviewed. Patient, tumor, and treatment characteristics and surgical complications and outcomes were compared between patients who underwent VRAM flap reconstruction of wounds that could have been closed primarily (flap group, n = 35) and those who had primary closure of the perineal wound (control group, n = 76). RESULTS: Overall, there were no significant differences in the incidence of perineal wound complications between the groups; the flap group had a significantly lower incidence of perineal abscess (9% versus 37%, p = 0.002), major perineal wound dehiscence (9% versus 30%, p = 0.014), and drainage procedures required for perineal/pelvic fluid collections (3% versus 25%, p = 0.003) than the control group had. Despite flap harvest and the need for donor site closure in the flap group, there was no significant difference in abdominal wall complications between groups during the study's mean patient followup of 3.8 years. CONCLUSIONS: VRAM flap reconstruction of irradiated APR defects reduces major perineal wound complications without increasing early abdominal wall complications. Strong consideration should be given to immediate VRAM flap reconstruction after chemoradiation and APR.

Utility of the omentum in the reconstruction of complex extraperitoneal wounds and defects: donor-site complications in 135 patients from 1975 to 2000

OBJECTIVE: To examine donor-site complications after omental harvest for the reconstruction of extraperitoneal wounds and defects. SUMMARY BACKGROUND DATA: The omentum, with its immunologic and angiogenic properties, is a versatile organ with well-documented utility in the reconstruction of complex wounds and defects. However, the need for laparotomy and the potential for intraabdominal complications have been cited as relative contraindications to the use of the omentum as a reconstructive flap. Further, few series have assessed long-term results, and no reports have focused on donor-site complications. METHODS: Patients who underwent reconstruction of extraperitoneal defects with the omentum at a single university healthcare system were identified by searching discharge databases and office records. Charts were reviewed to determine patient demographics, surgical indications and technique, postoperative complications, and outpatient follow-up. Patients with donor-site complications were compared with patients who had no complications using the Student t test and chi-square analysis. Statistical significance was defined at P <.05. RESULTS: From 1975 to 2000, the authors successfully harvested 135 omental flaps (64 pedicled, 71 free transfer) for reconstruction of the following defects: scalp (n = 16), intracranial (n = 1), orbitofacial (n = 33), neck (n = 8), upper extremity (n = 7), lower extremity (n = 4), intrathoracic (n = 3), sternal (n = 34), breast (n = 3), chest wall (n = 18), abdominal wall (n = 1), and perineal (n = 7). Donor-site complications in 25 patients (18.5%) included abdominal wall infection (n = 9), fascial dehiscence (n = 8), symptomatic hernia (n = 8), unplanned reexploration (n = 6), postoperative ileus (n = 3), gastrointestinal hemorrhage (n = 2), delayed splenic rupture (n = 1), gastric outlet obstruction (n = 1), and late partial small bowel obstruction (n = 1). Factors associated with increased donor-site complications included the use of pedicled flaps (compared with free tissue transfer), mediastinitis, advanced age, and pulmonary failure. Of note, 53 patients had undergone previous abdominal surgery; of these, 26 patients required extensive adhesiolysis and 4 patients sustained enterotomies. Eleven patients (8.1%) had partial flap loss and three patients (2.2%) had total flap loss. Mean length of stay was 28 days. Average follow-up was 2.4 years. The death rate was 5.9%. CONCLUSIONS: The omentum can be safely harvested and reliably used to reconstruct a diverse range of extraperitoneal wounds and defects. Donor-site complications can be significant but are usually limited to abdominal wall infection and hernia. Risk factors associated with complications include the use of pedicled flaps, mediastinitis, and pulmonary failure. This low rate of donor-site complications strongly supports the use of the omentum in the reconstruction of complex wounds and defects.     

Immediate breast reconstruction with the TRAM flap after neoadjuvant therapy

Neoadjuvant therapy is a relatively new weapon in the chemotherapeutic arsenal against breast carcinoma. However, there has been concern that preoperative chemotherapy might lead to an increased incidence of complications and delays in postoperative treatment. A retrospective study was performed at M.D. Anderson Cancer Center of all patients with locally advanced breast cancer who had undergone neoadjuvant therapy followed by mastectomy and immediate reconstruction with the transverse rectus abdominis musculocutaneous (TRAM) flap. Patients were evaluated for the incidence of complications and any delays in resumption of postoperative chemotherapy. Thirty-one patients underwent immediate reconstruction with the TRAM flap. Twenty-two patients were reconstructed with free TRAM flaps whereas 9 patients were reconstructed with pedicled TRAM flaps. Seventeen patients (55%) had complications postoperatively, but only 2 patients (6%) had a delay in the resumption of chemotherapy. Seven patients were smokers, five (71%) of whom had complications, which was not a significant difference from the rate in nonsmokers (50%). Although delays in postoperative chemotherapy occurred in smokers (29%, vs. 0% in nonsmokers), the number of patients was too small to attain statistical significance. Based on this study it is felt that immediate reconstruction with the TRAM flap can be performed safely in patients on a neoadjuvant protocol. Although not contraindicated, immediate reconstruction with the TRAM flap in smokers in this setting may be associated with higher morbidity.     

Reconstruction after soft tissue sarcoma resection in the setting of brachytherapy: a 10-year experience

Management of recurrent soft tissue sarcomas often involves surgical resection and adjuvant brachytherapy. This study reviews our experience in the management of these patients and proposes a logical approach toward reconstruction. All patients who underwent soft tissue sarcoma resection, adjuvant brachytherapy, and soft tissue flap reconstruction (pedicled or free) during the 10-year period from 1991 to 2000 were included in this study. There were 17 patients (14 male, 3 female) with a mean age of 51 years (range, 16-80 years). Soft tissue sarcomas were distributed in the lower extremity (n = 9), upper extremity (n = 5), and trunk (n = 3). Reconstruction was accomplished by regional transposition flaps (n = 10) and free tissue transfer (n = 7). The average defect size was 143 cm. Patients received 5 to 12 (mean, 8) brachytherapy catheters. The brachytherapy dose delivered ranged from 1600 to 4500 cGy (mean, 3773 cGy). Brachytherapy catheters were loaded with radioactive sources between 5 and 7 days postoperatively. All flaps in this series survived. One patient required return to the operating room for revision of a venous thrombosis with flap salvage. Closed suction drainage tubes were left in place until after the brachytherapy catheters were removed to avoid dislodging the catheters. Two patients developed postradiation partial-thickness skin necrosis with delayed secondary wound healing. This study demonstrates that soft tissue reconstruction in the setting of sarcoma resection and brachytherapy catheter placement is safe and efficacious. Postoperative wound healing complications can be minimized through coordination among the ablative surgeon, reconstructive surgeon, and radiation oncologist. Specifically, placement of microvascular anastomoses well away from the radiation target area is indicated whenever possible. Finally, removal of closed suction drainage tubes should be deferred until after the brachytherapy catheters are removed to minimize complications resulting from catheter dislodgement.     

Impact of skin-sparing mastectomy with immediate reconstruction and breast-sparing reconstruction with miniflaps on the outcomes of oncoplastic breast surgery

BACKGROUND: The aim of this study was to compare the outcomes of skin-sparing mastectomy (SSM) with immediate myocutaneous flap reconstruction and partial mastectomy with latissimus dorsi miniflap reconstruction (LDMF) for breast cancer. METHODS: Some 106 disease-free patients (57 SSM, 49 LDMF) who had breast reconstruction between 1991 and 1999 participated in this retrospective review. The mean duration of follow-up was 42 (range 6-102) months. Measured outcomes included surgical complications, functional disability, cosmetic result and psychological morbidity. RESULTS: SSM outcomes were less favourable than LDMF outcomes with regard to postoperative complications (14 versus 8 per cent), further surgical interventions (79 versus 12 per cent), nipple sensory loss (98 versus 2 per cent), restricted activities (73 versus 54 per cent) and cosmetic outcome by panel assessment. Anxiety about residual cancer and ease of breast self-examination were similar in both groups. CONCLUSION: LDMF was associated with fewer adverse surgical and physical sequelae than SSM, without compromising local control or cosmetic outcome. Both operations were associated with low psychological morbidity.     

Use of the anterolateral thigh flap as an alternative to the rectus flap in obese and overweight patients

INTRODUCTION: Oncologic reconstruction in obese patients can be challenging. Donor tissues, such as the rectus flap, can be excessively bulky and result in significant cosmetic and functional deformities. Although the use of the anterolateral thigh (ALT) flap as an alternative to the radial forearm flap has been extensively described, few studies have evaluated the use of the ALT flap as an alternative to the rectus flap. The purpose of this study was to evaluate our experience with the ALT flap in overweight or obese patients. METHODS: A retrospective review was conducted of all ALT flaps performed over a 2-year period at Memorial Sloan-Kettering Cancer Center. All patients with a body mass index (BMI) >25 kg/m2 were identified and evaluated. RESULTS: Twenty-seven patients underwent ALT flap reconstruction during the study period. Of these, 11 patients were overweight (BMI, 25.1-30 kg/m2) or obese (BMI, >30 kg/m2). Reconstructions were performed for a variety of oncologic defects, including head and neck (n = 7), extremity (n = 2), chest wall (n = 1), and abdominal wall (n = 1). Complications were, in general, mild and infrequent. One patient experienced a minor infection, 1 patient had partial flap loss, and 2 patients had partial skin graft loss at the donor site. There were no flap losses. CONCLUSIONS: The ALT flap is a safe and reliable flap for reconstruction of diverse defects in overweight or obese patients. Large flaps can be designed and tailored to the defect by harvesting variable amounts of skin, subcutaneous tissues, fascia, and muscle. The ALT flap may be a good alternative to the rectus flap in overweight or obese patients.     

Long-term survival analysis of free flap reconstruction in patients with collagen vascular disorders

BackgroundCollagen vascular disorders (CVD) are inflammatory diseases that can affect the blood vessels and soft tissues. Patients with CVD are often immunosuppressed, prone to hyper-coagulation, and represent a challenging patient cohort for free tissue transfer.MethodsA retrospective review of patients with CVD who underwent free flap reconstructions from 2000–2020 was performed at our institution. Inclusion criteria were patients 18 years old or older with the clinical diagnosis of CVD, including rheumatoid arthritis, Raynaud phenomenon, systemic lupus erythematosus, scleroderma, and sarcoidosis. A time-to-event analysis was performed to identify predictors of surgical complications.ResultsA total of 78 patients and 96 free flaps were included. The most common CVD were rheumatoid arthritis (n=36) and Raynaud's phenomenon (n=9). Type of flap included abdominal-based flap (26%), trunk-based flaps (32.3%), and extremity-based flaps (19.8%). The mean age was 56.7±14.6 years, and the mean BMI was 27.5±5.9 kg/m2. Antibody positivity was present in 25.6% of patients; 59% were on chronic steroids, 6.4% were on chronic anticoagulation, 35.9% had radiation therapy, and 29.5% had chemotherapy. Nine percent of patients had a history of prior flap loss, and 11.5% had a history of DVT or arterial thrombosis. The flap loss rate was 3.8%. Steroid treatment was associated with an increased risk of major complications after adjusting for the type of flap HR 2.5(1.3-4.9), p= 0.01. Specifically associated with a higher risk of cellulitis, OR 5.1 (1.1-24.5), p=0.02, and abscess, OR 5.7 (1.2-27.1), p=0.01.ConclusionFree flap reconstruction can be safely performed in patients with CVD. Perioperative optimization of steroids is important to promote wound healing and stabilize disease activity.     

Delaying the skin for TRAM flaps

This study was undertaken to determine whether a less extensive delay procedure would be as efficacious as the standard delay procedure in breast reconstruction.Between July 1996 and February 1999, 15 patients underwent delay procedures prior to breast reconstruction. Six patients underwent the standard delay procedure. Nine patients underwent a less extensive skin delay procedure. Transverse rectus abdominis myocutaneous (TRAM) reconstruction was performed 1 week after delay procedures.Average operating time was 28.7 minutes for the standard delay and 19.7 minutes for the skin paddle delay. The incidences of fat necrosis were 17% in the standard delay group and 22% in the skin paddle delay group. The incidences of partial flap loss/slow healing were 17% in the standard delay group and 22% in the skin paddle delay group. The incidence of complications in each group was the same: approximately 1 per patient.Operating times were not statistically different between the two groups (p = 0.06). There was no increase in the incidence of slow healing/partial flap loss or fat necrosis in the skin delay group. The skin delay procedure for TRAM flaps seems to provide a concise delay procedure that does not increase the incidence of complications in those high-risk patients.     

Safety and risk factors for breast reconstruction with pedicled transverse rectus abdominis musculocutaneous flaps: a 10-year analysis

BACKGROUND: The purpose of this study is to examine the effect of various risk factors on complications in patients undergoing pedicled transverse rectus abdominis musculocutaneous (TRAM) flap breast reconstruction. METHODS: A retrospective review of 224 pedicled TRAMs in 200 patients over a 10-year period was carried out. Patients were divided into subgroups based on smoking history, weight, radiation status, and pedicle type. Complication rates were calculated and logistic regression analysis was used to identify risk factors. RESULTS: Logistic regression identified active smoking as a statistically significant risk factor for developing multiple (2 or more) flap complications (P = 0.0061) and TRAM infection (P = 0.0255), while former smoking was a risk factor for multiple flap complications (P = 0.01) and TRAM-delayed wound healing (P = 0.0433). Obesity (body mass index > or =30) was found to be a statistically significant risk factor for overall (1 or more) donor-site complications (P = 0.0281), overall flap complications (P = 0.0375), multiple flap complications (P = 0.0002), TRAM-delayed wound healing (P = 0.0334), and minor flap necrosis (P = 0.0075). CONCLUSIONS: This study identified that active or former smoking and obesity contribute to a significant complication rate, while overweight body habitus, use of double-pedicled flaps, and pre-TRAM radiation do not. This second decade "look-back" on pedicled TRAM flap breast reconstruction emphasizes the need for appropriate patient selection to achieve successful results with pedicled TRAM breast reconstruction.     

Ischemic complications in pedicle, free, and muscle sparing transverse rectus abdominis myocutaneous flaps for breast reconstruction

Muscle sparing and perforator flaps techniques for breast reconstruction have focused in reducing the donor site morbidity. Theoretically this may result in a less robust blood supply to the flap. The purpose of this study was to assess flap ischemic complications with the pedicle, free, and the different muscle sparing transverse rectus abdominis myocutaneous (TRAMs) flaps for breast reconstruction and determine the factors associated with these complications. A total of 301 consecutive patients that underwent 399 breast reconstructions were retrospectively reviewed. Patient, oncologic, and reconstruction data were recorded. A flap ischemic complication scale was design including: wound healing problems, skin flap necrosis, fat necrosis, partial flap loss, and total flap loss. Analysis of donor site complications, bilateral and unilateral reconstructions were also performed. There were 147 pedicle TRAM and 154 free TRAM with the following subgroup distribution: MS-0 = 102; MS-1 = 37; and MS-2 = 15 patients. The groups were comparable in relation to age, comorbidities, cancer stage, and treatment. The overall complication rate after reconstruction had no statistical differences between the groups. The variables related to flap ischemia were statistically lower in the free TRAM. Mild and severe fat necrosis were the indicators with a statistical difference. The MS-0 group had lower ischemic complications and fat necrosis than the pedicled group, but no differences were observed for the MS-1 and MS-2 groups. The same results were seen in the unilateral reconstructions but not in the bilateral ones. No differences in donor site bulging or hernia were observed between the groups. In our study, the free TRAM flap demonstrated lower ischemic complications than the pedicle TRAM. A trend for decreased flap blood supply when more muscle is preserved and less number of perforators are used with a constant tissue volume was observed.     

TRAM flap breast reconstruction for patients with advanced breast disease

Transverse rectus abdominis musculocutaneous (TRAM) breast reconstruction in patients with advanced breast cancer is controversial. Management of these patients is often complex and consists of surgical extirpation, postoperative radiation, chemotherapy, and in some cases bone marrow transplantation. Few studies have attempted to examine patient long-term survival and overall satisfaction with the surgical procedure. This study examines one center's experience with patients undergoing breast reconstruction for stage III and stage IV breast carcinoma. A retrospective review was performed of all patients undergoing TRAM reconstruction with stage III or IV breast cancer. Surviving patients and family members were contacted for follow-up. Patients were asked to grade their satisfaction with the reconstructive procedure on a 5-point scale (5 points, extremely satisfied; 1 point, extremely dissatisfied). Postoperative complications and time to return to work were also recorded. During a 10-year period (1991-2000) 21 women underwent TRAM reconstruction for advanced breast cancer. Twenty patients had stage III disease and 1 patient had stage IV disease. Mean patient age was 49 years. A total of 26 TRAM flaps were performed; 5 patients had bilateral procedures. Of the 26 TRAM flaps, 17 were immediate and 9 were delayed, and 20 were free and 6 were pedicled. Follow-up averaged 6.5 years (range, 2-10 years). Postoperative complications occurred in 7 patients and included fat necrosis (N = 3), hematoma (N = 2), cellulitis (N = 1), delayed donor site healing (N = 2), and seroma (N = 1). There were no flap losses. Patients were able to return to normal activities or work at an average of 10.6 weeks. Eleven patients developed recurrent disease. Nine patients (43%) succumbed to their disease during the follow-up period. In these patients the average interval between TRAM reconstruction and death was 3.7 years (range, 1-6.5 years). Eleven patients or surviving family members participated in the patient satisfaction survey. The average satisfaction grade was 4.6 points. All patients would repeat the TRAM reconstruction again. Patients with advanced breast cancer can be considered appropriate candidates for TRAM reconstruction. The results of this study indicate that patients with advanced breast cancer do not have an increased rate of postoperative complications, and they recover within a reasonable time from their surgical procedure despite adjuvant radiation and chemotherapy. Furthermore, the majority of patients are satisfied with their reconstructed breast and postoperative course, and would choose this reconstructive option again.
