Despite the popularity of latissimus dorsi (LD) flap in breast reconstruction, a breast implant is often necessary to achieve sufficient volume. Prior reports describe fat grafting to the LD flap as a secondary procedure to correct contour deformities and improve volume. Our institution has instituted autologous breast reconstruction with an LD flap and immediate fat transfer (LIFT).
A retrospective review of all patients undergoing the LIFT procedure was undertaken. Patient age, total volume of fat transfer, length of follow-up, need for adjuvant therapy, and complications were recorded. The procedure begins with harvest of the LD flap and fat. Prior to disorigination of the latissimus muscle, fat is injected into the flap. Flap harvest is then completed and inset to create a breast mound.
Eighteen patients underwent LIFT procedures over 3 years with an average follow-up of 8.7 months (range, 2-24). Four breasts (22.2%) had previously received adjuvant radiation therapy. The mean total fat grafting volume was 515.5 mL (range, 325-730) per breast. The average estimated fat graft take was 66.8% (range, 50-80%). Four patients (22.2%) experienced complications.
Autologous augmentation of the LD flap with lipotransfer has been used to avoid placement of an implant. We improve the technique by performing lipotransfer during index reconstruction. Furthermore, we perform lipotransfer prior to disorigination of the LD muscle to minimize trauma to the flap and increase the efficiency of fat grafting. Our experience demonstrates that this technique is a viable autologous alternative to microsurgical breast reconstruction.
尽管背阔肌(LD)皮瓣在乳房重建中很受欢迎,但通常仍需要植入乳房假体以获得足够的体积。先前的报告将脂肪移植到LD皮瓣描述为一种纠正轮廓畸形和增加体积的二次手术。我们机构开展了采用LD皮瓣和即刻脂肪转移(LIFT)的自体乳房重建术。
对所有接受LIFT手术的患者进行回顾性研究。记录患者年龄、脂肪转移总量、随访时间、辅助治疗需求和并发症情况。该手术首先获取LD皮瓣和脂肪。在背阔肌离断之前,将脂肪注入皮瓣。然后完成皮瓣获取并植入以形成乳房隆起。
18例患者在3年内接受了LIFT手术,平均随访8.7个月(范围2 - 24个月)。4例乳房(22.2%)先前接受过辅助放疗。每侧乳房平均脂肪移植总量为515. mL(范围325 - 730 mL)。平均估计脂肪移植成活率为66.8%(范围50% - 80%)。4例患者(22.2%)出现并发症。
通过脂肪移植对LD皮瓣进行自体增大已被用于避免植入假体。我们通过在初次重建时进行脂肪移植来改进该技术。此外,我们在背阔肌离断之前进行脂肪移植,以尽量减少对皮瓣的创伤并提高脂肪移植效率。我们的经验表明,该技术是显微外科乳房重建的一种可行的自体替代方法。
