- Abstract
- Carotid bruit is a physical sign derived from the turbulence of carotid blood flow and has been rgarded as one of the imponant risk factor of ischemic stroke. To estimate a crude prevalence of carotid bruit in ischemic stroke in Korea at present time, and evaluate the correlation of carotid bruit with carotid stenosis and site of ischemic lesion, we investigated the brain imaging studies (computed tomography and magnetic resonance imaging)and cerebral angiographict finding of fifty patiens with caoti bruit.Thirty-nine (3.9 %) ot of nine hundred and ninety-six ischemic stroke patients had bruit around the carotid bifurcation. And the other eleven cases who did not have
ischemic stroke were detected to have carotid bruit during the routine neurological
examination at the bedside.Th presence of infarction in one side of carotid territory was
not significantly differentwhether the bruit was heard or not in that side, but the
presece of carotid stenosis in angiographY had a tendency to be significantly
different by the audible bruit on that side. Carotid bruit does not necessarily reflect
the infarction of that side, but can only be used as a predictor of ipsilateral extracranial
carotid occlusive disease in this preliminary study. Further extensive prospective study is needed for the exact prevalence of rate and the clinical usefulss of the carotid bruit in Korea.
