Abstract P2-19-05: Oncoplastic breast conserving surgery with perforator flap in breast cancer patients

Abstract

Abstract Purpose : Oncoplastic breast surgery has been used widely as a treatment protocol for breast cancer. Thoracodorsal artery perforator (TDAP) flap and intercostal artery perforator (ICAP) flap can provide adequate cover without sacrificing any muscle and allow closing of the donor sites in inconspicuous sites. Therefore, among the oncoplastic volume replacement techniques indicated using local flap that can adequately cover the volume of breast, TDAP and ICAP are especially suggested. This study describes the use of TDAP and ICAP flap techniques after breast conserving surgery. Methods : From March 2010 to August 2012, 38 patients with breast cancer received breast reconstruction. All patients who were selected had small- to moderate-sized defects on breasts, middle aged, and were not sensitive to scars. The TDAP flap is the first choice for performing the surgery, but if the perforator of the TDAP flap is not found, a dissection toward the anterior area to find an adequate perforator is made and the serratus anterior artery perforator is normally used. Otherwise after the dissection is performed more anterior, ICAP can be used. If the perforator penetrates the LD muscle, the TDAP flap can be used. The perforator that penetrates from the serratus anterior muscle is also used in the anterior area. Otherwise, ICAP can be used in partial breast reconstruction. The TDAP flap can be applied to any defect site regardless of the size of the defect area. Results : The mean age was 44.9 years and the average follow-up interval was 6 months. The average specimen weight was 98g. Complications developed in 4 cases including 3 cases of venous congestion, though self-limited, and 1 case of wound disruption on the inframammary fold suture area. Majority of the patients were satisfied with the cosmetic result. Conclusion : Thoracodorsal artery perforator flap (TDAP) and intercostal artery perforator flap (ICAP) techniques can be reliable and useful in correcting breast deformity after breast conservation surgery, especially in patients with small- to moderate-sized defects on breasts. Key Words : intercostal artery perforator flap, thoracodorsal artery perforator flap Oncoplastic surgery, ICAP, TDAP. Citation Information: Cancer Res 2013;73(24 Suppl): Abstract nr P2-19-05.
