|Stroke management||Stroke risk|
Improved methods are required to identify patients with asymptomatic carotid stenosis at high risk for stroke. Whether surgery is beneficial for patients with asymptomatic carotid stenosis is controversial. Carotid endarterectomy clearly benefits patients with symptomatic severe stenosis (SCS), but the risk of stroke is so low for asymptomatic patients (ACS) that the number needed to treat is very high. Better methods of identifying patients who are likely to develop stroke would improve the risk-benefit ratio for carotid endarterectomy.
