High rate of restenosis after carotid artery stenting in patients with high-grade internal carotid artery stenosis

Objective Carotid endarterectomy (CEA) is the goldstandard procedure for the majority of patients with high-grade symptomatic internal carotid artery stenosis and also for specified high-grade asymptomatic stenoses; however, a proportion of patients are treated with carotid endovascular therapy. We aimed to document medium-term clinical and neurosonographical outcome after carotid artery stenting (CAS).
