颈动脉内膜切除术(CEA)被认为是预防症状性或无症状性颈动脉狭窄发生卒中的有效方式。一些前瞻性随机试验已证明颈动脉支架置入术(CAS)可以作为这类疾病的治疗方式之一,但其疗效并不优于CEA。目前极其缺乏两者疗效相比的长期随访资料。为此,Steinbauer等报道了一项前瞻性、随机 Carotid endarterectomy (CEA) is considered as an effective way to prevent the onset of symptomatic or asymptomatic carotid stenosis. Some prospective randomized trials have demonstrated that carotid stenting (CAS) can be used as a treatment for these conditions, but its efficacy is not superior to that of CEA. There is an extremely lack of long-term follow-up data comparing the efficacy of the two. To this end, Steinbauer et al reported a prospective, randomized
