Abstract

Background Historically, breast-conserving surgery may not be pursued when the oncologic deformity is too significant and/or not tolerant of radiotherapy. Reconstruction using recruitment of upper abdominal wall tissue based on the intercostal artery perforating vessels can expand breast conservation therapy indications for cases that would otherwise require mastectomy. This report aims to describe the expanded use of the intercostal artery perforator (ICAP) as well as detail its ease of adoption. Methods All patients who underwent ICAP flaps for reconstruction of partial mastectomy defects at a single institution were included. Demographic data, intraoperative data, and postoperative outcomes were recorded. Intercostal artery perforator flap outcomes are compared with standard alloplastic reconstruction after mastectomy. Results Twenty-seven patients received ICAP flaps compared with 27 unilateral tissue expanders (TE). Six cases included nipple-areolar reconstruction, and 6 included skin resurfacing. The average defect size was 217.7 (30.3–557.9) cm3. Plastic-specific operative time was significantly longer in the ICAP cohort (P < 0.01) with no difference in total operative time (P > 0.05). Length of stay was significantly longer, and major postoperative complications were significantly more common in TE patients (P < 0.01, P > 0.05). Seven TE patients required outpatient opiate refills (26%) versus 1 ICAP patient (4%) (P = 0.02). One ICAP patient required additional surgery. Patients reported satisfaction with aesthetic outcomes. Average follow-up in the ICAP cohort was 7 months. Conclusions Lumpectomy reconstruction using ICAP flaps can effectively expand breast conservation therapy indications in resection of breast skin, nipple-areola, or large volume defects. This technique is adoptable and of limited complexity. Enhancing breast-conserving surgery may improve outcomes compared with mastectomy reconstruction. Intercostal artery perforator patients may require fewer opioids, shorter hospital stays, and lower operative burden.
