High-Volume LVA-New Surgical Technique for Treatment of Lymphoceles in the Groin

Background: Groin lymphoceles are common postoperative complications after vascular interventions that can be difficult to treat, especially in recurrent or complex cases. While lymphovenous anastomosis (LVA) is a potential, minimally invasive option, its limited flow capacity may not provide sufficient drainage in large lymphoceles. We present a novel high-volume LVA technique that uses larger veins to directly drain the lymphocele cavity. Methods: Five patients with six groin lymphoceles, all previously treated unsuccessfully with conventional methods (mean 3.3 surgeries), underwent high-volume LVA (HV-LVA). The technique involved direct anastomosis of a large regional vein to the lymphocele cavity. Lymphatic inflow points were identified with Patent Blue or ICG when possible. Outcomes were assessed over 6-14 months. Results: In total, seven HV-LVAs were performed. Three lymphoceles (50%) were successfully treated with a single operation; three required revisions due to venous occlusion. All patients were successfully treated without recurrence. The average number of surgeries per patient was 2.2. Conclusions: High-volume LVA may be an effective option for therapy-resistant inguinal lymphoceles, providing greater drainage capacity than standard techniques. Further studies are needed to confirm its long-term efficacy and safety.
