Radiofrequency Ablation (RFA)
In Radiofrequency Ablation (RFA), the doctor inserts a small catheter into the diseased vein through a small incision, under ultrasound guidance for an accurate and live view. Consistent and uniform heat is delivered to contract the collagen in the vein walls, causing them to collapse and close. After the vein is closed, blood is diverted to healthy veins which improves circulation. Over time, the treated vein is absorbed into surrounding tissue.
