Endovascular electrocoagulation with a bipolar electrode and alternating current: a follow-up study in dogs.

Endovascular electrocoagulation of the anterior tibial artery in dogs was performed with two different bipolar electrodes. Follow-up showed revascularization when a short-tip electrode was used, but no revascularization when a long-tip electrode was used. Histologic study showed complete occlusion of the artery by an organized thrombus adherent to the vessel wall.
