Published data suggest that the presence of carotid bruit is a reasonably accurate indicator of carotid stenosis in symptomatic persons. Fewer data are available with which to assess its role in asymptomatic persons. In symptomatic persons, Ziegler and colleagues [1] found a sensitivity of 0.29 and a specificity of 0.88 for detecting stenosis greater than 50%; the collaborators of the North American Symptomatic Carotid Endarterectomy Trial [2] found a sensitivity of 0.62 and a specificity of 0.61 for detecting stenosis of 70% to 99%; and Hankey and Warlow [3] ...
