This study evaluated the effectiveness of a pocket-sized ultrasound device in preoperative planning for lymphaticovenular anastomosis (LVA) to enhance lymphedema treatment outcomes.
A retrospective analysis was performed on 24 patients who underwent LVA for secondary upper extremity lymphedema between June 2020 and August 2022. Patients were categorized into two groups: the ultrasound group, which used a pocket-sized device (Vscan Air), for preoperative vein identification, and a control group that did not. Preoperative lymphatic mapping was performed using indocyanine green lymphography, and suitable veins for anastomosis were identified using ultrasound. Upper extremity lymphedema index and incision length were compared.
Participants in the ultrasound group had a shorter average incision length (2.85 ± 0.48 cm) than those in the control group (3.23 ± 0.78 cm, p = 0.038), indicating a more targeted and minimally invasive approach. Although volume reduction rates were not significantly different, the pocket ultrasound device facilitated more precise vein selection, enhancing surgical planning.
Pocket-sized ultrasound devices provide a cost-effective and practical solution for vein identification during LVA, particularly in resource-limited settings. While high-frequency ultrasound offers superior resolution, portable devices could become standard tools for lymphatic surgery with continued technological advancement.
本研究评估了一种袖珍超声设备在淋巴静脉吻合术（LVA）术前规划中的有效性，以提高淋巴水肿的治疗效果。
对2020年6月至2022年8月期间接受LVA治疗继发性上肢淋巴水肿的24例患者进行回顾性分析。患者分为两组：超声组，使用袖珍设备（Vscan Air）进行术前静脉识别；对照组，不使用该设备。术前使用吲哚菁绿淋巴管造影进行淋巴造影，并使用超声识别适合吻合的静脉。比较上肢淋巴水肿指数和切口长度。
超声组患者的平均切口长度（2.85±0.48 cm）短于对照组（3.23±0.78 cm，p = 0.038），表明采用了更具针对性和微创的方法。虽然体积减少率没有显著差异，但袖珍超声设备有助于更精确地选择静脉，改善手术规划。
袖珍超声设备为LVA期间的静脉识别提供了一种经济高效且实用的解决方案，特别是在资源有限的环境中。虽然高频超声具有更高的分辨率，但随着技术的不断进步，便携式设备可能会成为淋巴手术的标准工具。
