Abstract Objective To compare the diagnostic value of mesenteric vascular ultrasound and CT angiography (CTA) in emergency acute mesenteric vascular embolism, so as to provide a reference for clinical diagnosis. Methods From October 2018 to October 2020, 80 patients with suspected acute mesenteric vascular embolism admitted to Department of Emergency, Zhejiang Taizhou Hospital were selected as study objects. All patients underwent mesenteric vascular ultrasound, CTA and digital subtraction angiography (DSA) examinations. DSA diagnosis results as the gold standard, and the diagnostic value of mesenteric vascular ultrasound and CTA were analyzed. Results The sensitivity of mesenteric vascular ultrasound was 86.49%, the specificity was 100.00%, the positive predictive value was 100.00%, the negative predictive value was 37.50%, and Youden index was 0.865; the sensitivity of CTA was 97.30%, the specificity was 100.00%, and the positive predictive value was 100.00%, negative predictive value was 75.00%, Youden index was 0.973. The sensitivity of CTA in the diagnosis of acute mesenteric vascular embolism was higher than that of mesenteric vascular ultrasound, and the difference was statistically significant (P < 0.05). Conclusion Both methods are beneficial to the diagnosis of the disease types and etiology in the emergency department, and CTA is more sensitive to acute mesenteric vascular embolism than mesenteric vascular ultrasound, which is worthy of application.
