Carotid artery bruits

Carotid artery bruits. Extra and abnormal sounds heard through the stethoscope just lateral to the larynx are often the result of turbulent arterial blood flow due to stenosis of the carotid arteries. Diagnosis is often made non-invasively by colour Doppler ultrasound or magnetic resonance angiography (MRA). Stenosis or occlusion often occurs near the common carotid bifurcation.
