Our aim was to identify optimal incision sites for LVA in extremity lymphedema that would result in the most effective drainage effect for reducing limb edema and enhancing patients' quality of life.

designing the optimal incision sites and identifying functional lymphatic vessels imaging is crucial for success, primarily due to its efficacy in draining edematous lymphatic fluid and reducing swelling in patients with lymphedema. In this study, we conducted patients with LVA lymphedema to investigate the correlation between LVA incision design, intraoperative functional lymphatic vessel assessment, postoperative limb reduction, and patient satisfaction.
