Abstract:
Objective:To explore the efficacy of indocyanine green angiography (ICGA) in preventing flap perfusion disorders after liposuction combined with abdominoplasty.Methods:A retrospective analysis was conducted on the clinical data of patients who underwent liposuction combined with abdominoplasty and used ICGA to evaluate flap perfusion in the Department of Plastic Surgery, Union Hospital Affiliated to Tongji Medical College, Huazhong University of Science and Technology from March 2022 to March 2024. After the incision was sutured, 2 ml of indocyanine green solution (2.5 mg/ml) was intravenously injected, and a fluorescence angiography imaging system was used to observe perfusion in the distal flap and the suture site. Lack of fluorescence within 3 minutes after injection indicated local hypoperfusion. Flap perfusion was observed on the 1st, 2nd, and 3rd days after surgery, and compared with intraoperative ICGA results.Results:A total of 52 female patients were included, aged 29-55 years, with an average age of 33.8 years. The size of the flap excised during surgery ranged from 12 cm×29 cm to 19 cm×42 cm, and the liposuction volume was 300-1 400 ml. Among the 52 patients, 3 cases showed blood supply disorders in the central area of the distal flap during intraoperative ICGA examination. Timely release was performed, but there was still obvious tension in the distal flap. All 3 cases developed distal flap hypoperfusion after surgery, with sizes ranging from 3 cm×3 cm to 7 cm×5 cm. The range was basically consistent with the area shown by ICGA. After dressing changes, the flaps healed well. During a 12-month follow-up, the three patients reported no wound discomfort or dissatisfaction with the appearance. The ICGA images of the remaining 49 patients were good during the operation, and the blood supply of the flaps was good after the operation. After a 12-month follow-up, the abdominal appearance of 52 patients was satisfactory.Conclusion:ICGA for evaluating flap blood supply in liposuction combined with abdominoplasty has the advantages of simple operation, fast imaging speed, and high diagnostic accuracy. It has application prospects in preventing flap necrosis after liposuction combined with abdominoplasty.
