ClosureFast endovenous radiofrequency ablation for great saphenous vein and small saphenous vein incompetence: Efficacy and anatomical failure patterns.

Background: Recurrence rates and patterns after endovenous radiofrequency ablation (ERFA) are poorly documented.

Objective: To assess the incidence and anatomical recurrence patterns of saphenous vein reflux after ERFA.

Method: Two hundred patients previously treated with ERFA were recalled for clinical assessment and venous-duplex ultrasound at three years post-treatment.
