Description: Update of the 1996 U.S. Preventive Services Task Force statement about screening for asymptomatic carotid artery stenosis (CAS) in the general population.
Methods: The U.S. Preventive Services Task Force examined the evidence on the natural history of CAS; systematic reviews of the accuracy of screening tests; observational studies of the harms of screening and treatment of asymptomatic CAS; and randomized, controlled trials of the benefits of treatment for CAS with carotid endarterectomy.
Recommendation: Do not screen for asymptomatic CAS in the general adult population. (Grade D recommendation).
