Complete, bilateral common carotid and left vertebral occlusion without major neurological or mental deficit occurred in a 62-year-old man. Patency of both internal carotid arteries was subsequently demonstrated by arteriography and at surgery. Bilateral subclavian to internal carotid artery bypasses were performed utilizing 8-mm Dacron grafts. The patient is now relieved of all symptoms and both grafts are patent at five months follow-up.
