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
