Mean age 41.9 years, 31 male, and 12 (29.1%) patients present with multiple CCADW. At the moment of TCD evaluation, 17 (41.4%) patients were being treated with antiplatelets and the rest under Heparin. TCD monitoring lasted in average 53.3 minutes and demonstrated at the moment of evaluation, MES in four carotid arteries (11.1%) of 3 patients and 13 (28.8%) abnormal BHI in 11 patients. Six IEs occurred in 3 patients, 3 strokes, and 3 transient ischemic attacks. In the univariate analysis correlating IE with clinical and ultrasonographic findings, the degree of carotid stenosis, the presence of multiple CAD, and the presence of MES plus abnormalities of BHI were significantly associated with the risk of an IE. Multivariable analysis showed that only the presence of MES plus abnormal BHI were significant (<jats:italic>P<\/jats:italic> &lt; .001). MES and abnormal BHI were present in the 3 patients and in four arterial territories that had IE.<\/jats:p><\/jats:sec><jats:sec><jats:title>CONCLUSIONS<\/jats:title><jats:p>TCD can identify a
