BACKGROUND AND OBJECTIVES: This study evaluated the effectiveness of a pocket-sized ultrasound device in preoperative planning for lymphaticovenular anastomosis (LVA) to enhance lymphedema treatment outcomes.
METHODS: 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.
RESULTS: 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.
CONCLUSION: 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.
