Key result
Carotid duplex ultrasonography detects mild stenosis in ~28% of examined vessels, supporting primary screening use.
Why the study?
The efficiency of Duplex Ultrasonography for screening and monitoring of Carotid Artery Stenosis was evaluated to improve risk stratification for ischemic stroke.
Does Duplex Ultrasonography (DUS) efficiently screen and monitor Carotid Artery Stenosis (CAS)?

Does Duplex Ultrasonography (DUS) efficiently screen and monitor Carotid Artery Stenosis (CAS)?
Duplex ultrasonography is an effective and sensitive imaging modality for detecting varying degrees of carotid artery stenosis and plaques.
DUS supports noninvasive CAS screening and monitoring; reinforces its role in vascular guidelines while highlighting need for standardized protocols.
Aim: To evaluate the efficiency of Duplex Ultrasonography (DUS) for monitoring and screening of Carotid Artery Stenosis (CAS).Methods: PubMed, Web of Science, Cochrane, and SCOPUS were searched for relevant articles. The quality assessment of the included studies was conducted according to the Cochrane Risk of Bias Tool.Results: Our meta-analysis included six articles. We found that carotid DUS could detect mild CAS in 25%, moderate CAS in 13%, severe CAS in 14.5% of the examined vessels, detection of carotid artery plaques in 36.5% of the examined vessels, and abnormal intima thickness in 21.5% of the examined vessels.Conclusion: DUS is an important exam in the identification of patients with symptomatic CAS. It can improve clinical practice and provide cost-effective management for CAS. Carotid DUS showed high specificity and sensitivity in the diagnosis of CAS, especially a severe degree of stenosis

Saduakas et al. (2024) conducted a meta-analysis in Carotid Artery Stenosis (n=1,051). Duplex Ultrasonography vs. Other imaging modalities or clinical assessments was evaluated on Detection of mild carotid artery stenosis (95% CI 14.9-41.9). Carotid duplex ultrasonography effectively detected mild carotid artery stenosis in 28.4%, moderate in 14.3%, and severe in 17.2% of examined vessels, supporting its use as a primary screening modality.
