Recent reports suggest that the DUS may be inaccurate in over 28% of patients.

Three groups of patients were defined. Group 1 had DUS measured ICA stenosis of &gt;50%; Group II had a DUS measured ICA stenosis of &lt;50%; Group III had complete ICA occlusion on DUS.<\/jats:p><\/jats:sec><jats:sec id=\"S0317167100004212_abs3\"><jats:title>Results:<\/jats:title><jats:p>Sixty-seven patients (69 arteries) were included in the study.

Group II consisted of 19 patients and on cerebral angiography, none of these patients had a stenosis of &gt;50% - a misclassification rate of 0%. Group III consisted of five patients in whom DUS showed complete ICA occlusion. The angiogram confirmed the occlusion in all five patients \u2013 a misclassification rate of 0%.
