Abstract
We investigated the clinical significance of carotid bruits in 238 patients with ischemic stroke using carotid ultrasonography. We recognized carotid bruits in 4 1 (17.2%)of the patients on auscultation of the neck. Patients with carotid bruits tended to have risk factors of ischemic heart disease and to be male. and symptomatic cerebral infarction with significantly more frequent than in patients without carotid bruits (p<0.05). Internal carotid artery stenosis (area of stenosis ≥50%), turbulence flow, and peak systolic velocity ≥150 cm/sec were observed significantly more frequently in patients with carotid bruits (p<0.05). Age, diabetes mellitus, hypertension. cigarette smoking. and dyslipidemia were not proved to have a significant correlation with the presence of carotid bruits. These findings indicate that carotid bruits are associated with advanced atherosclerosis in many organs.
