Abstract：
BACKGROUND: Gluteal augmentation with autologous fat transfer is one of the fastest growing aesthetic surgical procedures worldwide over the past decade. However, this procedure can be associated with high mortality from fatal pulmonary fat embolism events caused by intramuscular injection of fat. Ultrasound-guided fat grafting allows visualization of the transfer in the subcutaneous space, avoiding intramuscular injection.
OBJECTIVE: The aim of this study was to assess the safety and efficacy of gluteal fat grafting performed with ultrasound-guided cannulation.
METHODS: A retrospective chart review of all patients undergoing ultrasound-guided gluteal fat grafting at the authors\' center between 2019 and 2022 was performed. All cases were performed by board-certified and board-eligible plastic surgeons under general anesthesia in ASA Class I or II patients. Fat was only transferred to the subcutaneous plane when over the gluteal muscle. Patients underwent postoperative follow-up from a minimum of 3 months up to 2 years. Results were analyzed with standard statistical tests.
RESULTS: The study encompassed 1815 female patients with a median age of 34 years. Controlled medical comorbidities were present in 14%, with the most frequent being hypothyroidism (0.7%), polycystic ovarian syndrome (0.7%), anxiety (0.6%), and asthma (0.6%). Postoperative complications occurred in 4% of the total cohort, with the most common being seroma (1.2%), local skin ischemia (1.2%), and surgical site infection (0.8%). There were no macroscopic fat emboli complications or mortalities.
CONCLUSIONS: These data suggest that direct visualization of anatomic plane injection through ultrasound guidance is associated with a low rate of complications. Ultrasound guidance is an efficacious adjunct to gluteal fat grafting and is associated with an improved safety profile that should be considered by every surgeon performing this procedure.

摘要：
背景：在过去的十年中，自体脂肪转移的臀骨扩张术是全球增长最快的美容手术之一。然而,该手术可能与致命性肺脂肪栓塞事件的高死亡率相关,并在媒体中受到广泛关注.已经确定在肌内空间中注射脂肪与这种并发症相关。超声引导的脂肪移植允许皮下空间转移的可视化，避免肌肉注射。
目的：本研究的目的是评估利用超声（US）引导插管进行臀脂移植的安全性和有效性。
方法：对2019年至2022年在我们中心接受超声引导下臀肌脂肪移植的所有患者进行了回顾性图表回顾。所有病例均由符合董事会认证和董事会资格的整形外科医生在ASAI级或II级患者的全身麻醉下进行。脂肪仅在臀肌上方转移到皮下平面。患者接受了至少3个月至2年的术后随访。使用标准统计检验对结果进行分析。
结果：研究期间有1,815名女性患者，中位年龄为34岁。14％存在受控的医疗合并症，最常见的是甲状腺功能减退症（0.7％），多囊卵巢综合征（0.7%），焦虑（0.6%），和哮喘(0.6%)。术后并发症发生在总队列的4%，最常见的是血清肿（1.2%），局部皮肤缺血（1.2%），和手术部位感染（0.8%；表1）。肉眼可见的脂肪栓塞并发症或死亡率为0％。
结论：这些数据表明，使用US指导直接可视化解剖平面注射与低并发症发生率相关。美国指南是臀脂移植的有效辅助手段，并与安全性改善相关，每位进行臀脂移植的外科医生都应考虑。
