Detection of Intracranial Emboli in Patients with Symptomatic Extracranial Carotid Artery Disease
Stroke 23:1652-1654, Siebler,M.,et al, 1992

Article Abstract
Clinically silent formed-element embolism of ophthalmic or cerebral arteries was demonstrated in all three patients.Embolic events occurred only in the territory of the symptomatic internal carotid artery.The average rate of cerebral embolization at transcranial Doppler ultrasonography was 4.1/hr,with a mean signal duration of 47 msec.No emboli were found in control subjects.The observed high frequency of silent embolism of the intracranial arteries detected by transcranial Doppler monitoring in patients with recurrently symptomatic extracranial carotid artery disease should encourage studies of the prognostic and therapeutic implications of this method.
