Definition of Carotid Bruit Sound

Carotid Bruit is an abnormal sound characteristic of atherosclerosis that the cardiologist hears through a stethoscope placed over the carotid artery at the base of the neck.

The sound, a murmur that occurs during systole (contraction of the left ventricle), represents turbulence as blood passes through areas of the carotid artery where atheromas (collections of atherosclerotic plaque) occlude the inner channel of the carotid artery.

Carotid bruit is a diagnostic sign that indicates the presence of carotid stenosis (narrowing of the carotid artery) and increased risk for stroke
