Standard cervical carotid arteriography was performed on 36 patients and
compared with results of noninvasive Doppler arterial imaging and
intravenous angiography (IVA). The 72 carotid arteries were anatomically
classified by standard angiograms as follows; group 1 (normal), 13
arteries; group 2 (wall disease [50% stenosis]), 14 arteries; group 3
(moderate stenosis [5-% to 75% stenosis]) 12 arteries; group 4 (severe
stenosis [greater than 75%]), 15 arteries; and group 5 (complete
occlusion), 18 arteries.
