Diagnosis and treatment of restenosis after carotid endarterectomy and stenting

As a classic cerebral revascularization procedure, carotid endarterectomy （CEA） has been widely used in the treatment of high-grade extracranial carotid artery stenosis. In recent years, carotid artery stenting （CAS） has a trend to replace CEA gradually. A large number of clinical studies have found that in addition to perioperative complications, carotid restenosis after CEA and CAS also has important influence on the prognosis of patients. This article reviews the current status of diagnosis and treatment of restenosis after CEA and CAS. Key words: endarterectomy, carotid;  stentts;  carotid stenosis
