Loss of a breast free flap is a relatively rare but catastrophic occurrence. Our study aims to identify risk factors for flap loss and to assess whether different salvage techniques affect flap salvage. We performed a retrospective review of all breast free flaps performed at a single institution from 2000 to 2010. Overall, 2138 flaps were performed in 1608 patients (unilateral, 1120 and bilateral, 488) with 44 flap losses (2.1%). Age, body mass index, smoking, radiation, chemotherapy, and surgeon experience did not affect flap loss. Abdominal flaps based on a single perforator were at significantly higher risk for flap loss compared with flaps based on multiple perforators (P = 0.0007). Subgroup analysis of the subset of 166 compromised free flaps (flaps requiring a return to the operating room, an intraoperative anastomotic revision, or loss/partial loss of a free flap) demonstrated deep inferior epigastric perforator, and other flaps (superficial inferior epigastric artery and superior gluteal artery perforator) were significantly associated with flap loss [odds ratio (OR) 5.20; P = 0.03 and OR 6.91; P = 0.0004, respectively] compared with transverse rectus abdominis myocutaneous and muscle-sparing transverse rectus abdominis myocutaneous flaps. Although an intraoperative complication was not associated with a flap loss, the need for a reoperation was strongly predictive (P < 0.0001). Flap salvage was the highest within the first 24 hours (83.7%) and significantly less between days 1 and 3 (38.6%; P < 0.0001) and beyond 4 days (29.4%; P < 0.0001). Longer ischemia time was significantly associated with flap loss (P = 0.04). Salvage techniques (aspirin, heparinzation, thrombectomy, and thrombolytic) had no impact on flap salvage rates. Heparinization and thrombolytics were associated with higher loss rates (OR 3.40; P = 0.003 and OR 10.36; P < 0.0001, respectively). Free flap loss following breast reconstruction is multifactorial with higher losses in superficial inferior epigastric artery and gluteal flaps, single-perforator abdominal flaps, and longer ischemia times. Salvage rates are most successful within the first 24 hours, and the use of heparinization, aspirin, and thrombolytics does not improve salvage rates.
The versatility and location of the anterolateral thigh (ALT) flap make it well suited for lower extremity reconstruction. The purpose of this study was to evaluate surgical and functional outcomes by specific anatomic regions in the lower extremity to better define the role of the ALT flap in lower extremity reconstruction. A retrospective review of patients undergoing lower extremity reconstruction with an ALT flap between July 2002 and December 2010 was performed. Total 46 patients underwent lower extremity reconstruction with an ALT flap, of whom 29 (63%) had a pedicled flap and 17 (37%) a microvascular free flap. Defects were located in the hip/buttocks (n = 8), groin (n = 13), thigh (n = 8), knee (n = 5), leg (n = 6), and foot/ankle (n = 6). The mean postoperative follow-up was 4 months. Total flap loss occurred in two patients (4%). There were 11 recipient site complications (24%). The most common complication was recipient site seroma, which occurred in five patients (11%), all of whom had hip/buttock or groin defects. Overall, 38 patients (83%) returned to their preoperative functional status. The ALT flap is an effective method of lower extremity reconstruction. It can be performed as a pedicled or free flap, with good surgical and functional outcomes.
