Abstract：Objective To analyze the diagnostic value of echocardiography and multi-slice spiral CT in patients with emergency aortic dissection(AD).Methods A total of 180 patients with AD diagnosed by aortic angiography from January 2020 to October 2022 were selected.The diagnostic value of echocardiography and multi-slice spiral CT in AD was compared.Results In this study,there were 180 patients with AD,including 123 cases(68.3%)of Stanford type A and 57 cases(31.7%)of Stanford type B.The overall coincidence rate of echocardiography in the diagnosis of AD was 95.6%(172/180),and the coincidence rate of Stanford type A AD was 100%(123/123),which had no significant difference compared with multi-slice spiral CT(P＞0.05).The coincidence rate of Stanford type B AD by echocardiography was 86.0%(49/57),which was lower than that of multi-slice spiral CT(100%,57/57)(P＜0.05).The coincidence rate of echocardio-graphy for aortic valve abnormality was 100%(129/129),which was higher than that of multi-slice spiral CT(82.9%,107/129)(P＜0.05).The coincidence rate of echocardiography for the diagnosis of abnormal aortic arch was 96.2%(153/159),which was lower than that of multi-slice spiral CT(100%,159/159).Conclusion In the diagnosis and evaluation of AD,echocardiography and multi-slice spiral CT have advantages and disadvantages and diagnostic value,and should be com-bined when the patient＇s hemodynamics are stable,so as to make a comprehensive and accurate evaluation of the patient＇s AD and cardiac function.
