Abstract：Objective: To explore the diagnostic value and scanning technique of echocardiography in double aortic arch,and analyze the causes of missed diagnosis and improve the accuracy of echocardiography diagnosis. Methods: Echocardiographic features of thirty-one cases of double aortic arch diagnosed by CT or surgery were retrospectively analyzed. Results: Twenty-five cases were diagnosed by echocardiography. Echocardiographic manifestations: In the long axis plane of suprasternal view, the probe was rotated 30° clockwise and 30° anticlockwise along the coronal section of the human body respectively, and the left and right aortic arches were displayed. In the short axial plane of the suprasternal view, two aortic arches on both sides of the trachea could be found(showing cordate changes). Three patients with left arch distal occlusion were misdiagnosed as right aortic arch, and three cases of equilibrium type were missed. Sixteen cases were associated with intracardiac malformation. Fifteen cases with different degrees of airway stenosis. Conclusion: Echocardiography can diagnose the double aortic arch accurately, and it should pay more attention to the continuous scanning and careful exploration of the suprasternal view, which is helpful to improve the accuracy of the double aortic arch ultrasound diagnosis.
