Abstract

The carotid stump is a known source of cerebral embolisms. Direct ultrasound sonographic visualization of a thrombus in the common carotid stump after development of a cerebral infarction is rare. We report a case of a 69-year-old man who presented with acute ipsilateral ischemic stroke with occlusion of the left common carotid artery, forming a stump proximal to the carotid bifurcation. Carotid duplex sonography revealed a mobile thrombus in the stump. An ipsilateral microembolic signal was observed by transcranial Doppler imaging.
