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.
