What is the current guideline for screening asymptomatic carotid artery stenosis in adults?

• A. Not recommended
• B. Recommended in all adults
• C. Only with symptoms
• D. Only after age 80

Answer: (A)

Screening asymptomatic carotid artery stenosis in adults is not recommended. Large studies show that finding asymptomatic stenosis through routine screening does not clearly reduce stroke risk and often leads to additional testing or interventions with real harms, such as perioperative stroke or death from procedures like carotid endarterectomy or stenting. Since the prevalence of clinically significant stenosis in the general population is relatively low and many detected cases never progress, the potential harms outweigh unproven benefits. The emphasis instead is on aggressive management of vascular risk factors—blood pressure and cholesterol control, diabetes management, smoking cessation, and appropriate antiplatelet therapy—along with careful evaluation if symptoms develop or if a patient falls into a specific high-risk scenario where targeted screening might be considered.
