Little is known about the extracranial carotid arteries of patients with acute stroke who need intensive care. This study reviewed color\u2010coded carotid duplex sonographic examinations of the extracranial carotid arteries of patients with acute critical hemispheric ischemic stroke.<\/jats:p><\/jats:sec><jats:sec><jats:title>Methods<\/jats:title><jats:p>We retrospectively reviewed 30 consecutive patients who had acute critical hemispheric ischemic stroke and received color\u2010coded carotid duplex sonography in the intensive care unit. The presence of occlusive carotid artery disease was correlated with clinical features, vascular risk factors, and outcomes.<\/jats:p><\/jats:sec><jats:sec><jats:title>Results<\/jats:title><jats:p>Overall, 57% of the patients (17 of 30) had an occlusive internal carotid artery, and 44% of patients with atrial fibrillation (7 of 16) also had occlusive carotid disease. Eventually, 73% of the patients (21 of 30) had poor outcomes, and 57% (17 of 30) died. The contributing factors to a poor outcome were older age, an initial conscious disturbance, endotracheal intubation, and occlusive carotid disease, with the most significant factor being older age (<jats:italic>P<\/jats:italic>= .022; odds ratio, 27.76). The factors contributing to death were endotracheal intubation, occlusive carotid disease, and reversed ophthalmic flow, with the most significant factor being occlusive carotid disease (<jats:italic>P<\/jats:italic> = .014; odds ratio, 11.38). Soft homogeneously echogenic thrombi filling the lumen of the internal carotid artery and moving forward and backward with the carotid pulse were found in 3 patients. A small segment of ruptured plaque that was floating forward and backward with pulsation was found in 1 patient.<\/jats:p><\/jats:sec><jats:sec><jats:title>Conclusions<\/jats:title><jats:p>Occlusive carotid artery disease is not uncommon among Chinese patients who have had an acute critical hemispheric infarction.
