QS6. Defects In Protein Trafficking in Venous Malformations: A Novel Disease Model

Abstract

Purpose: Vascularized lymph node transfer (VLNT) helps to restore physiological lymphatic function. Although effective, postoperative impairment of donor-site lymphatic function and iatrogenic lymphedema following lymph node transfer from the groin remains a pressing concern.Methods: Prospective analysis of VLNT patients that had undergone radioisotope-free dual fluorescent tracer assisted harvest was performed at our institution from September 2013 to August 2020. Reverse lymphatic mapping of the lower extremity was performed with indocyanine green (ICG). Blue dye was utilized in both white light and near infrared spectra for visualization and localization of donor site lymphatic structures. Demographics, intraoperative details, and surgical outcomes were recorded.
