carotid artery bruit

• Atherosclerotic plaque or stenosis in common carotid artery or major vessels.
• Normal vessel.

Asymptomatic bruits are a risk factor for stroke, and 75% of strokes occur in the carotid circulation. The majority of patients with bruits will have stenosis of 50% or more. The vast majority (90%) of strokes occur without prior symptoms.
