Thoracodorsal artery perforator flap as an autologous alternative to acellular dermal matrix

Abstract

Abstract Background Thoracodorsal artery perforator (TDAP) flap is one of the relatively new techniques in breast reconstruction. This pedicled flap retains the benefits of perforator flaps as regards minimal donor site morbidity without the need for microvascular anastomosis. Its role in partial breast reconstruction has been well documented. However, there are few reports about the role of this flap in total breast reconstruction. Methods This study included 47 cases who presented to the breast unit of the National Cancer Institute of Cairo University from 2013 to 2015. All patients underwent nipple-sparing mastectomy with immediate implant-based reconstruction. The TDAP flap was used to complete the subpectoral pocket for the implants in a way similar to the acellular dermal matrix. Results Overall complication rate was 14.9%. Capsular contracture occurred in 6.4%.There were no donor site complications. The majority of patients were satisfied with their cosmetic results. Sixty-eight percent rated their result as “excellent” or “good.” Conclusion Thoracodorsal artery perforator flap can play a significant role in total breast reconstruction. In settings with limited resources, this flap can serve as an available autologous alternative to acellular dermal matrix.
