title: Asymptomatic angiographic occlusion of the internal carotid artery: an indication for emergency endarterectomy.
abstract: A 56-year-old man had retinal artery embolization from a carotid artery atheroma. Complete occlusion of the internal carotid artery occurred during cerebral angiography, but the patient developed no acute symptoms of cerebral ischemia. The patient immediately underwent emergency carotid endarterectomy which he tolerated well, and follow-up angiography nine days later demonstrated continued patency. The patient has remained neurologically unchanged.
