Abstract Objective To investigate the ultrasonographic characteristics of abnormal fetal aortic arch diagnosed by prenatal ultrasound. Methods The echocardiographic data of 168 pregnant women with abnormal fetal aortic arch diagnosed by prenatal ultrasound from June 2018 to June 2021 in Guangxi Zhuang Autonomous Region Maternal and Child Health Hospital were analyzed, and the ultrasonographic characteristics of abnormal aortic arch in the three-vessel trachea section, the long axis section of active bow, and the coronal section at the beginning of descending aorta were summarized. Results In 168 fetuses, 68 cases had right-sided aortic arch and branch deformity, 42 cases had left arch left catheter vagus right subclavian artery, 32 cases had aortic coarctation, 15 cases had aortic arch rupture, and 11 cases had double aortic arch rupture. Conclusion The abnormal aortic arch has characteristic ultrasonographic changes in the three-vessel trachea bow, the long axis section of the active arch, and the coronal section of the descending aorta, which has important clinical value in the diagnosis of abnormal aortic arch.
