ObjectiveTo compare the clinical efficacy of carotid endarterectomy (CEA) and carotid artery stenting (CAS) in the treatment of patients with carotid artery stenosis, and to provide a more abundant evidence-based medicine for the treatment of CEA and CAS in patients with carotid artery stenosis. MethodsForty patients with carotid artery stenosis were randomly divided into CEA group and CAS group based on the operative indication. Patients in CEA group were given carotid endarterectomy treatment and those in CAS group were given carotid artery stenting treatment. Then clinical efficacy of the two groups were observed and compared. ResultsIn terms of the occurring rate of perioperative complications, cardiovascular events in 3 months after operation, and some major end events such as stroke, death and so on, the comparative difference between the two groups was of no statistical significance (P > 0.05). Through the followed-up visits of 12 months, the comparative difference between the two groups was also of no statistical significance (P > 0.05) in terms of the occurring rate of carotid artery restenosis and disabling or fatal stroke. ConclusionsFor patients with severe extracranial carotid stenosis under indication of operation treatment, carotid endarterectomy and carotid artery stenting are of equivalent clinical efficacy, and both of them are of high security, although further study with large-amount and evidence-based medical data in long term from multiple centers is still in need.
