A total of 116 carotid endarterectomies were performed in patients with a totally occluded opposite internal carotid artery over a 10-year period from 1983 until 1992. The average age of patients was 66.4 years; 75% were men and 25% were women. The average degree of stenosis on the operated side was 76.7%. Twenty-one patients (18.1%) had had a documented previous stroke referrable to the side of the occlusion; 22 had a neurologic deficit attributable to the occluded vessel at the time of preoperative evaluation. Indications for surgery included transient ischemic attacks in 35 (30.2%), ipsilateral stroke in 10 (8.6%), amaurosis fugax in 11 (9.5%), and high-grade asymptomatic stenosis in 60 (51.7%). Forty-eight percent of the procedures were performed using local anesthesia, with intraluminal shunts inserted in all except one patient. The combined 30-day mortality and stroke morbidity in this population was 4.3%, which is comparable with a combined stroke and death rate of 4.0% among 956 patients without contralateral carotid occlusion undergoing endarterectomy during this period. This experience suggests that endarterectomy can be performed safely in the patient with internal carotid occlusion and is an important mechanism for the prevention of stroke.
