How should we manage women with fat necrosis following autologous breast reconstruction: An algorithmic approach

Background: The deep inferior epigastric perforator (DIEP) flap is the standard of care in autologous breast reconstruction. The superficial inferior epigastric artery perforator flap (SIEA) is an alternative reconstructive option, with the compromise of less donor-site morbidity but variable perfusion to subscarpal fat zones. Fat necrosis is a known complication from marginal perfusion variability. Volumetric analysis of fat necrosis has not been performed between the two reconstructive options, nor has the amount of flap necrosis following radiation. Our objective was to compare rates and volume of fat necrosis between single-perforator DIEP and SIEA flap techniques. Methods: A single-center, blinded, prospective cohort study of patients randomized between SIEA and DIEP breast reconstruction was conducted over 2 years (June 2011–July 2013). Inclusion criteria were women undergoing immediate reconstruction following mastectomy. Randomization protocols were strictly followed. Fat necrosis volumetric analysis was determined by an ultrasound-trained attending surgeon at 12 months postoperatively. Patient demographics and adjuvant/neoadjuvant cancer treatment were analyzed. Statistical analyses included Mann-Whitney U tests, chi square, and/or Fisher exact tests. P values of 0.05 or less were considered significant. Results: Fat necrosis was detected in 11 of 46 flaps (23.9%), with a median area of 17.9 cm2. There was no significant difference in prevalence of fat necrosis between the two flap types (P = 0.19). Postoperative radiation did not increase the prevalence (P = 0.30) or extent (P = 0.92) of fat necrosis. Conclusion: Single-perforator DIEP and SIEA flaps have comparable rates of fat necrosis. Postoperative radiation did not result in increased prevalence or extent of fat necrosis.
