A multi-institutional review of endovenous thermal ablation of the saphenous vein finds male sex and use of anticoagulation are predictors of long-term failure.

Background: To review long-term outcomes and saphenous vein (SV) occlusion rate after endovenous ablation (EVA) for symptomatic varicose veins.

Methods: A review of our EVA database (1998-2018) with at least 3-years of clinical and sonographic follow-up. The primary end point was SV closure rate.
