Occlusion of all four extracranial vessels with minimal clinica symptomatology. Case report

Abstract

A case of a 55-year-old man with occlusion of both vertebral, left common carotid and right internal carotid arteries is described. Also present was 95 per cent stenosis on the origin of the right external carotid artery with severe atherosclerotic disease on both subclavian and innominate arteries. Clinical symptoms consisted of blindness of the left eye; otherwise the patient was free of neurological signs. It is suggested that not only the presence of extracranial occlusive disease but also the status of the intracranial circulation, the time factor in which the extracranial vessels became occluded, and the adaptability of the individual to establish all possible means of collateral flow play their roles in correlation of extracranial atherosclerotic disease and clinical symptomatology-Additional Key Words extracranial cerebral vascular disease transient ischemic attacks extracranial collateral circulation cerebral angiography. © 1972 American Heart Association, Inc.
