Intercostal artery perforator flaps for partial breast reconstruction after breast-conserving surgery

Abstract

Introduction Breast conservative surgery’s objectives include a thorough oncologic excision and a satisfactory aesthetic outcome. The greatest strategy to prevent undesirable aesthetic outcomes is to use oncoplastic procedures to do so during conservative surgery in one step. For small to medium-sized breasts (up to C or D cup size), volume replacement treatments are advised, particularly in cases of bigger tumors. This entails inserting tissue into the tumor excision defect from a nearby or distant site. Musculocutaneous flaps, fasciocutaneous flaps, and most recently ‘perforator’ skin flaps have all been used in autologous tissue restoration. Due to the intercostal artery’s strong blood supply, anterior and lateral intercostal artery perforator (LICAP) flaps are dependable tissue sources. These flaps have the benefit of being able to fill the resection cavity, preventing further deformities. The study aimed to assess the feasibility of intercostal artery perforator flaps in partial breast reconstruction following breast-conserving surgery. Materials and methods The study was carried out on 42 breast cancer patients admitted to the surgical oncology unit, at Alexandria Main University Hospital in the duration between January 2021 and December 2022. A modified lateral intercostal artery perforator flap (mLICAP) and anterior intercostal artery perforator flap (AICAP) were used depending on the tumor location within the breast. The postoperative assessment was done by another breast surgeon and by the patient. Results Modified LICAP was used in 37 patients and AICAP was used in 5 patients. 90.5% of patients were satisfied with the aesthetic outcomes (85.7 gave excellent results). 69% of patients had excellent results based on the surgeon’s assessment. Complications were encountered in 11 patients in the form of seroma, hematoma, and minimal wound dehiscence. Conclusion Modified LICAP affords excellent access to the axilla and offers an option that facilitates both a pleasing aesthetic result and obviates the need for symmetrizing contralateral surgery to maintain breast symmetry. AICAP is a good option to partially reconstruct the breast following BCS for tumors located in the lower half of the breast.
