From the Department of Vascular Surgery, Mount Sinai School of Medicine, New York, New York Transient ischemic attacks have been attributed to emboli from the external carotid artery in patients with complete occlusion of the internal carotid artery. We report a patient with an external carotid stenosis and normal internal carotid who developed ipsilateral transient ischemic attacks. Real time B-mode ultrasonography demonstrated that the plaque obstructing the exter nal carotid artery extended into the carotid sinus. This may have served as a source of emboli into the internal carotid circulation.
