Abstract: Chronic atherosclerotic occlusion of carotid can lead to low cerebral blood flow and increase the risk of stroke. Drug therapy is the first choice for asymptomatic patients, while the patients with recurrent neurological symptoms may need surgical treatment. Extracranial-intracranial artery bypass (EIAB) is not better than medicine treatment. The operation risks of carotid endarterectomy (CEA) and carotidartery stent (CAS) are high with low success rate and the therapeutic effects remain to be verified. Therefore, the surgical indications should be strictly controlled. In this paper, the current status of treatment for chronic carotid artery occlusion was reviewed.
