Medical and Revascularization Therapies for Asymptomatic Carotid Stenosis

Asymptomatic internal carotid artery stenosis increases with age and is more common in men. Carotid endarterectomy and stenting have reduced stroke rates in patients with asymptomatic carotid stenosis in clinical trials. A variety of risk stratification methods are available for selection of patients with carotid stenosis for revascularization. In the past decade, there is increasing evidence that the rate of stroke declined with the use of aggressive multi-modal medical therapy. These developments have led to new clinical trials to compare revascularization versus aggressive medical therapy in patients with asymptomatic carotid stenosis.
