Abstract
Traditionally, surgical treatments such as stripping or high ligation were the mainstay for treating saphenous vein varicosities. However, with the emergence of endovenous laser ablation (EVLA) and radiofrequency ablation (RFA), treatments have become less invasive. In recent years, endovenous treatments using n-butyl-2-cyanoacrylate (NBCA), known as cyanoacrylate closure (CAC), have also appeared. Endovenous thermal ablation (ETA) and CAC are performed in the majority of cases for varicose veins, and they have become familiar to interventional radiologists. This article provides an overview of the diagnosis of lower limb varicose veins, basic treatments using ETA and CAC, and practical considerations regarding adverse events and troubleshooting.
