Abstract

Chronic venous disease with incompetent saphenous veins has variable treatment methods, including radiofrequency ablation (RFA) technique. RFA is a thermal treatment technique that is widely used worldwide with excellent treatment outcomes reported in many studies and currently recommended as the preferred treatment in guidelines of chronic venous diseases. Recently, in Korea, IC-RFA technique, which has different concept and principle from the existing RFA, has been developed and used in clinical practice. Unlike RFA that uniformly reproduces the ablation time and energy in incompetent saphenous veins, IC-RFA automatically controls the ablation time and energy according to the surrounding intravascular conditions. This technique has a theoretical benefit of transferring more energy for veins with larger diameters and reduced energy for small veins. Herein, we briefly introduce IC-RFA. (
