RESUMO
BACKGROUND: Secondary cosmetic breast surgery after primary augmentation with implant can be associated with an increased risk of adverse events. Partial/complete nipple-areola complex necrosis is particularly feared. In this preliminary study, the authors propose the utilization of indocyanine green (ICG) angiography to assess the blood supply of breast tissue after implant removal. OBJECTIVES: The main objective was to prevent skin and gland necrosis in revision breast surgery. METHODS: The authors performed a retrospective comparative analysis of 33 patients who underwent secondary breast surgery between 2018 and 2021 by a single surgeon (M.S.). Breast tissue perfusion was assessed in 16 patients by intraoperative ICG angiography at the end of implant removal and possible capsulectomy. Non-stained/non-fluorescent areas were judged to be low perfusion areas and were excised with short scar mastopexy. RESULTS: In the ICG angiography group, 7 patients (44%) showed an area of poor perfusion along the inferior pole; all of these patients underwent subglandular breast augmentation. Resection of the poor perfusion areas allowed an uneventful postoperative course. In the non--- ICG angiography group (17 patients), 5 patients experienced vertical-scar dehiscence/necrosis. We found a statistically significant association between the non-ICG angiography group and vertical scar dehiscence/necrosis, and also between vertical scar dehiscence/necrosis and subglandular implant placement (P = 0.04). CONCLUSIONS: Safer secondary surgery can be offered to patients undergoing secondary aesthetic breast procedures, especially when the first augmentation surgery is unknown-for example, implant plane, type of pedicle employed, if the implant is large and subglandular, and if capsulectomy is performed.
