Extraction atherectomy for the recanalization of totally occluded aortocoronary saphenous vein grafts

Abstract
This report describes the successful treatment of totally occluded aortocoronary saphenous vein grafts with percutaneous transluminal extraction atherectomy (TEC) in three patients with severe angina and high reoperative surgical risk. The method presented here may provide an alternative to overnight urokinase infusion or repeat surgery in high risk patients.
