Safety and efficacy of anterior intercostal artery perforator flaps in oncoplastic breast reconstruction

Introduction Partial breast reconstruction based on the anterior intercostal artery perforators (AICAP) has been suggested to avoid the unsightly ‘bird's beak’ deformity for lower pole breast cancers. The aims of this study were to evaluate the initial clinical experience of AICAP flaps in terms of safety and efficacy in oncoplastic breast reconstruction. Methods Between October 2013 and April 2020, AICAP flaps were offered to 30 patients with lower pole breast cancers. Hand‐held Acoustic Doppler assessments were undertaken to confirm adequate perforators. Surgical results were evaluated in terms of safety and efficacy. Patients were invited to complete sections of the Breast‐Q questionnaire at least 12 months postoperatively to assess patient satisfaction in terms of cosmetic outcome, physical and psychosocial wellbeing. Results Median operating theatre time for AICAP flap harvesting and positioning was 20 min (range 15–28 min). The median weight of resected breast specimens was 41 g (range 10–127 g). Total tumour size ranged from 7 to 35 mm (median 16 mm; three cases exhibited multifocal disease). Clear radial resection margins were achieved in 29 cases (96.7%). The median post‐operative stay was two days (range 2–3 days). There were two postoperative complications comprising delayed wound healing/fat necrosis, which resolved with monitoring and inadine dressings. Based on the Breast‐Q results, patients reported high levels of satisfaction with the physical appearance of their reconstructed breast, psychosocial and physical wellbeing. Conclusion AICAP flaps appear to be safe in restoring breast contour after wide excision of lower pole breast cancers, with high levels of patient satisfaction reported postoperatively. Anterior intercostal artery perforator flaps are advocated in partial breast reconstruction. These flaps permit wide resection of lower pole breast cancers, with low re‐excision rates. They restore breast contour, and are associated with high levels of patient satisfaction.
