Donor site sensitivity after breast reconstruction with deep inferior epigastric artery perforator flap

The aim of this study was to examine pressure sensitivity at the donor site after breast reconstruction with deep inferior epigastric artery perforator (DIEAP). In a cross-sectional survey, 2 groups of patients were analyzed. The DIEAP group consisted of 30 women who had previously had secondary breast reconstruction with DIEAP flap after mastectomy for breast cancer. The control group consisted of 7 women with no previous abdominal incisions planned for secondary breast reconstruction with DIEAP. Pressure thresholds were tested within the margins of the abdominal wall using Semmes-Weinstein monofilaments. In the DIEAP group a pattern of higher pressure thresholds was observed in the proximity of the scar. Comparing the 2 groups, significant higher pressure thresholds were found in the DIEAP group in the scar on both sides and in the midline from the scar to the umbilical level. Our data show that the abdominoplasty performed during breast reconstruction with DIEAP reduces cutaneous sensitivity in the donor site area.
