Steam ablation versus radiofrequency and laser ablation: an in vivo histological comparative trial

There is an increasing use of minimal invasive techniques to treat saphenous vein reflux. Among these radiofrequency ablation (RFA), endovenous laser ablation (EVLA), and foam sclerotherapy are frequently used. A new method of thermal ablation is the steam vein sclerosing (SVS) system. This study evaluates the histological changes after ablation of the saphenous veins in goats with RFA, EVLA, and SVS.status: publishe
