Ultrasound Guided Microfoam Endovenous Ablation
This is the only FDA approved foam treatment for Varicose Vein disease of the Great Saphenous Vein (GSV) system of the leg. It is ideal for extremely tortuous (twisted) veins which have been very difficult to treat even with the laser and radiofrequency (VNUS/Venefit) catheter systems. The Varithena system does not require a catheter delivery or any form of mechanical vein manipulation to affect closure. The unique properties of its microfoam (1% polidocanol) make it highly visible on Duplex Ultrasound and allow the foam to be massaged into the tortuous tributary of the diseased Varicose Vein branches. The patented microfoam agent has been demonstrated by the FDA to be highly effective and greatly minimize risk for distant foam embolization and deep vein thrombophlebitis (DVT).
Furthermore, unlike laser and radiofrequency ablations which require a form of heat energy, the Varithena system does not depend upon a heat source and is virtually pain free. This means no painful local infiltration injections along the course of the treated vein and no post op discomfort. This system has not been approved for treatment of disease in the Small Saphenous Vein (SSV) which runs along the back of the calf. The Varithena system is covered by Medicare and certain PPO’s. Microfoam endovenous ablation is suitable for patients with complicated problems, patients with skin changes around the ankle and patients who have multiple medical problems that would have prevented them from undergoing corrective venous surgery.
