Aortic arch and carotid arteriography was used in the North American Symptomatic Carotid Endarterectomy Trial (NASCET) to evaluate the percentage of stenosis. The diameter of the narrowest portion of the lesion is divided by the normal internal carotid artery diameter distal to the lesion. This procedure may be associated with a 1-2% risk of stroke.
