Experimental determination of the best time and duration for endovenous great saphenous vein electrocoagulation

The successful treatment of lower extremity chronic venous insufficiency includes the elimination of all sources of venous reflux. Endovenous ablation of varicose veins with radiofrequency ablation and endovenous laser therapy has reported advantages over traditional open surgical treatment but is costly. We have described a simple endovenous electrocoagulation apparatus and technique that provoke immediate selective venous wall damage and use a conventional electrosurgical generator as the energy source. In this study, we aim to determine the best power and the time of electrocoagulation necessary to cause intima and media but not adventitia layer damage in lower limb varicose vein treatment.
