Abstract：Objective: To investigate the value of three-vessel-trachea view in the diagnosis of fetal right aortic arch. Methods: Ultrasonic characteristics in three-vessel-trachea view and clinical outcome of 61 fetuses with right aortic arch diagnosed by prenatal ultrasound in our hospital were retrospectively analyzed. Results: Sixty-one cases of fetal right aortic arch were diagnosed by prenatal ultrasound, with simple right aortic arch in 41 cases, double aortic arch in 2 cases, right aortic arch with cardiac abnormalities in 14 cases, right aortic arch with extracardiac malformations in 2 cases, and right aortic arch combined with cardiac and extracardiac malformations at the same time in 2 cases. Thirty-nine cases of live births postpartum confirmed prenatal diagnosis. Five cases of right aortic arch combined with other serious malformations chose induced labor(including 4 cases of autopsy results confirming the prenatal diagnosis, 1 case of induced labor without autopsy). Two cases are still under a close follow-up. One case of postpartum echocardiography result didn’t concord with the prenatal ultrasound diagnosis. Fourteen cases were lost from follow-up. Conclusion: Three-vessel-trachea view is a reliable view to diagnose fetal right aortic arch in prenatal ultrasonic examination, and simple fetal right aortic arch may not cause obvious clinical symptoms.
