A procedure by which a surgeon gently removes atherosclerotic plaque that has accumulated inside the internal carotid artery, a large blood vessel which delivers the largest portion of the brain's blood supply. The plaque can generate stroke symptoms by diminishing blood flow to large areas of the brain, or by dislodging small fragments which travel into the brain and interrupt local blood flow.
Multiple studies have determined that CEA is the safest way to reduce stroke risk in the majority of patients who suffer from this serious condition, which is commonly known as carotid stenosis.
