A carotid bruit is a bruit or sound heard over the carotid artery area, usually by a nurse, paramedic, or physician during auscultation. It is usually the result of a stenosis of the carotid artery, and is unlikely to be heard if the stenosis occludes less than 40% of the diameter of the artery. Likewise, a stenosis of greater than 90% may not be heard, as the flow may be too low.
Many carotid bruits are discovered incidentally in an otherwise asymptomatic patient. A carotid duplex ultrasound may be useful in determining the origin of the bruit, the severity of the stenosis causing it, and the bruit's hemodynamic effects.
A CT scan may be indicated for patients with ultrasound-proven carotid disease who are at a higher risk for cerebrovascular accidents such as stroke.
