Abstract
• The direction of supraorbital and frontal artery flow and its response to compression of the superficial temporal, facial, and angular arteries were measured in 250 carotid arteries in 114 patients. All patients had arch and/or selective carotid arteriography. The carotid arteries were placed into the following three groups: hemodynamically normal, greater than 60% occlusion of the internal carotid artery, and total occlusion of the internal carotid artery. The test's accuracy was 94.5% in the hemodynamically normal group, 68.8% in the totally occluded group, and only 51.4% in the group with hemodynamically significant stenosis.
Although the carotid Doppler examination is not reliable in detecting hemodynamically significant lesions of the internal carotid artery, it is valuable in assessing the adequacy of collateral cerebral circulation.
