Why Screening for Asymptomatic Carotid Artery Stenosis Isn't Recommended
Published: Nov 17, 2023
While screening for asymptomatic carotid artery stenosis might seem beneficial, experts advise against it. Discover the reasons behind this recommendation.
Low Prevalence and Risk
Screening for carotid artery stenosis in asymptomatic individuals is not recommended due to its low prevalence and the minimal annual risk of stroke. The prevalence of severe stenosis is less than 3% even in older adults, making widespread screening impractical.
False Positives and Risks
The use of noninvasive screening tests can result in more false positives than true positives. This can lead to unnecessary interventions and increased risk of complications, including stroke and death associated with surgical procedures.
Expert Guidelines
Major health organizations, including the US Preventive Services Task Force, recommend against routine screening. Their guidelines emphasize the lack of evidence supporting benefits and highlight potential harms.
