摘要
Stroke is the second leading cause of death globally and accounts for an estimated 5.5 million deaths each year worldwide.[1]Revascularization of the carotid artery is one of the key procedures to reduce the incidence of stroke.Chronic total occlusion(TO)and near-total occlusion(NO)of the carotid artery are rare.Treatment for TO and NO is controversial with potential complications,including periprocedural stroke,intracranial hemorrhage,and carotid-cavernous fistula(CCF).[2]There have been attempts to implement carotid artery endarterectomy(CEA)and endovascular treatment,but the success rates were far from satisfactory.For patients with TO,the success rate of revascularization is around 40%and 60%,respectively,for CEA and endovascular technique.[3]For patients with NO,the morbidity and mortality rates are 3%and 9%,respectively.
