Endovenous thermal ablation for varicose veins: Strengths and weaknesses

Endovenous ablation is a frequently used method for treating varicose veins. Endovenous laser ablation is the most frequently used technique, followed by radiofrequency ablation. Endovenous thermal treatments heat the vein, leading to thrombotic occlusion and finally fibrosis of the vein wall. Endovenous steam ablation is a new technique that has not yet been extensively studied. In this article, the procedures, strengths, and weaknesses of the currently available endovenous thermal ablation treatments are discussed.
