Venefit™ RF Ablation
Venifit™ (formerly known as VNUS Closure) and EVLT are very similar techniques. In venoclosure, the greater saphneous vein is accessed using ultrasound for guidance. A radio frequency fiber is placed in the vein and advanced to the level of the groin. Radiofrequency energy is used to destroy the lining of the greater saphenous vein. Once the endothelium, or lining of the vein is ablated, this “tricks” the body into thinking that the vein is dead and the body converts the dysfunctional vein into a fibrous scar. Blood does not flow through the scarred vessel and instead blood is re-routed to normal veins with functioning valves back to the heart.
Venoclosure and EVLT provide the same end result as stripping without the pain, long recovery time and loss of work from vein stripping. Endovenous ablation has the added benefit of being more durable with a 94% success rate at two years versus a 60% success rate for vein striping.
