Stroke risk and treatment of asymptomatic carotid artery stenosis

The optimal therapeutic regimen for patients with asymptomatic carotid artery stenosis (ACS) has been controversial.Early research suggests that carotid endarterectomy (CEA) is effective for the treatment of patients with severe ACAS.In recent years,as a minimally invasive treatment,carotid artery stenting (CAS) is as effective as CEA.It has a trend of replacing CEA.In recent 10 years,medicine standardized treatment has made great progress.Recent studies have shown that the risk of stroke is lower using the optimal medical treatment in patients with ACAS compared with CEA and CAS.The key of choosing optimal therapeutic regimen is to identify the high risk patients with stroke.
