Abstract
Carotid duplex ultrasonography is a common noninvasive technique for evaluating cases of suspected extracranial carotid artery occlusive disease. This manuscript describes the procedure, with an emphasis on positive findings. A review of 16 published studies, totaling 2,168 arteriogram correlations, demonstrates a sensitivity, specificity, and overall accuracy of 95%, 73%, and 91%, respectively, for the detection of stenosis. The ability of the technique to predict the presence of plaque ulceration and intraplaque hemorrhage is less well defined. Carotid duplex ultrasonography is a highly accurate technique for the detection of extracranial carotid artery occlusive disease.
