<unk>  is used to reduce the risk of stroke associated with carotid artery stenosis. Carotid stenosis can have no symptoms, or have symptoms such as transient ischemic attacks (TIAs) or strokes. While historically endarterectomy has been the treatment for carotid stenosis,<unk>  is an alternative intervention for patients who are not candidates for surgery. High risk factors for endarterectomy, which would favor<unk>  instead, include medical comorbidities (severe heart disease, heart failure, severe lung disease) and anatomic features (contralateral carotid occlusion, radiation therapy to the neck, prior ipsilateral carotid artery surgery, intra-thoracic or intracranial carotid disease) that would make surgery difficult and risky.
