Atherosclerotic plaques and high grade stenosis in the carotid circulation are responsible for symptoms of cerebral and retinal ischemia. Identification of these lesions by angiography has been the "gold standard" for which the decision of endarterectomy depended. The recent introduction of high resolution carotid ultrasonography has allowed us to compare thirty-seven surgical specimens with the results of preopertive screening with angiography. UCI had a 97% correlation whereas angiography was accurate only 70%. More importantly there were ten negative angiograms in patients with clinically active ulcerative plaque disease. If surgery were based solely on the angiographic appearance of ulcerative plaques or high grade stenosis, then less than half of the patients have received the correct treatment. UCI deserves to be considered the new reference standard.
