Lymphaticovenular anastomosis (LVA) is increasingly utilized in the treatment of lymphedema. This study aims to assess the efficacy and safety of the "Overlapping" LVA technique, which addresses the size mismatch between lymphatic and venous vessels in lymphedema treatment.
Between August 2022 and April 2023, seventeen patients diagnosed with lymphedema were enrolled in this study. The severity of lymphedema in these patients was classified according to the International Society of Lymphology (ISL) staging system.All patient underwent LVA procedures, anastomosis techniques including the Overlapping, end-to-end and octopus anastomosis. The techniques of anastomosis, anastomosis time, patency rate, and volume of limb lymphedema were evaluated.
Our study enrolled 17 lymphedema patients who underwent the LVA procedure. All patients showed significant postoperative improvement in limb edema. The mean drainage volume was 472.29 ml. The Overlapping technique demonstrated a 100% success rate as assessed by clinical observation and intraoperative Indocyanine Green (ICG) lymphography. The average anastomosis time was 5.3 min, reducing operative time compared to traditional methods.
These findings suggest that the Overlapping technique could serve as a valuable addition to the current LVA technique. This Overlapping anastomosis technique provides a wide range of applications for lymphatic anastomosis treatment and prevention of lymphedema.
淋巴管静脉吻合术（LVA）在淋巴水肿治疗中的应用越来越广泛。本研究旨在评估“重叠”LVA技术的疗效和安全性，该技术可解决淋巴水肿治疗中淋巴管与静脉血管大小不匹配的问题。
2022年8月至2023年4月，17例被诊断为淋巴水肿的患者纳入本研究。根据国际淋巴学会（ISL）分期系统对这些患者的淋巴水肿严重程度进行分类。所有患者均接受LVA手术，吻合技术包括重叠吻合、端端吻合和章鱼式吻合。评估吻合技术、吻合时间、通畅率和肢体淋巴水肿体积。
本研究纳入17例接受LVA手术的淋巴水肿患者。所有患者术后肢体水肿均有明显改善。平均引流量为472.29毫升。通过临床观察和术中吲哚菁绿（ICG）淋巴管造影评估，重叠技术成功率达100%。平均吻合时间为5.3分钟，与传统方法相比缩短了手术时间。
这些发现表明，重叠技术可成为当前LVA技术的一项有价值补充。这种重叠吻合技术为淋巴吻合治疗和预防淋巴水肿提供了广泛的应用。
