Abstract: Objective To discuss the detection rate of the arc of Bühler(AOB)in CTA and DSA examinations and its clinical significance.Methods A computerized retrieval of academic papers concerning AOB from the databases of PubMed,Web of Science,Scopus,Embase,Google Scholar,CBM,CNKI,WanFang,VIP and Baidu Scholar was conducted.Stata 17.0 software was used to make meta-analysis.Results A total of 11 articles including 3 837 subjects and 65 AOB cases were included in this analysis.The pooled prevalence of AOB was 1.9％(0.8％-3.2％).CTA showed a pooled prevalence of AOB of 2.0％(0.5％-4.3％)and DSA showed a pooled prevalence of AOB of 1.8％(0.5％-3.9％).Conclusion Clinically,AOB is a rarely-seen anatomical variation.The possibility of the presence of an AOB should be considered when performing the relevant abdominal surgery so as to avoid causing operation difficulties and complications such as abdominal visceral organ ischemia or bleeding.(J Intervent Radiol,2024,33:604-609)
