The annual risk of stroke from asymptomatic carotid stenosis is about 0.5-2.5%. After successful carotid endarterectomy (CEA) the risk of suffering a stroke amounts to about 2% per year. CEA therefore seems to impose an unnecessary risk upon the patient. However, a stenosis with more than 80% luminal narrowing, a rapidly progressing stenosis, and ulcers may increase the spontaneous risk and should be evaluated in randomized studies. The same applies to prophylactic CEA of asymptomatic stenosis before major cardiac or vascular surgery.
无症状性颈动脉狭窄每年的中风风险约为0.5%-2.5%。成功进行颈动脉内膜切除术后（CEA），每年中风的风险约为2%。因此，CEA似乎给患者带来了不必要的风险。然而，管腔狭窄超过80%、进展迅速的狭窄以及溃疡可能会增加自发风险，应在随机研究中进行评估。这同样适用于在重大心脏或血管手术前对无症状狭窄进行预防性CEA。
