The Preferred Treatment for Varicose Veins and CVI

The ClosureFast™ procedure (previously known as Venefit™) is a minimally invasive treatment for varicose veins and Chronic Venous Insufficiency (CVI) in which one of the experienced doctors at Precision VIR inserts an Endovenous Radiofrequency Ablation (RFA) Catheter to collapse and close enlarged leg veins. After the vein is sealed shut, blood then naturally reroutes to healthy veins.
