Population Adult General Population1
Recommendation Do not screen with ultrasound or other screening tests.

Grade: D

Risk Assessment

The major risk factors for carotid artery stenosis (CAS) include: older age, male gender, hypertension, smoking, hypercholesterolemia, and heart disease.

However, accurate, reliable risk assessment tools are not available.

Balance of Benefits and Harms

Harms outweigh benefits.

In the general population, screening with carotid duplex ultrasound would result in more false-positive results than true positive results. This would lead either to surgeries that are not indicated or to confirmatory angiography. As the result of these procedures, some people would suffer serious harms (death, stroke, and myocardial infarction) that outweigh the potential benefit surgical treatment may have in preventing stroke.

Other Relevant Recommendations from the USPSTF

Adults should be screened for hypertension, hyperlipidemia, and smoking. Clinicians should discuss aspirin chemoprevention with patients at increased risk for cardiovascular disease.

1. This recommendation applies to adults without neurological symptoms and without a history of transient ischemic attacks (TIA) or stroke. If otherwise eligible, an individual who has a carotid area TIA should be evaluated promptly for consideration of carotid endarterectomy.
