Abstract
Bruit heard in the neck is a commonly encountered sign in patients with cerebral ischemia or infarction, but it may also be present in patients of similar age and sex without such symptoms and signs. When heard in the neck of patients without clinical evidence of cerebrovascular disease, bruit is not an ominous clinical sign and does not indicate the need for surgical correction of obstructions in extracranial cerebral vessels. Bruits can change in intensity and locale, a phenomenon which most likely reflects changing circulatory dynamics secondary to changes in the degree of atherosclerotic disease in cerebral vessels. Bruit heard in the neck is a sign of cerebrovascular disease[long dash]not of cerebral Ischemia or cerebral infarction.
