Double aortic arch (DAA) is a type of vascular ring found on fetal echocardiography in approximately 1 in 2000–4000 pregnancies. In some cases of DAA, respiratory impairment occurs in infancy due to compression of the trachea, which is completely surrounded by the right aortic arch (RAA) and left aortic arch (LAA). The RAA and left ductus arteriosus were first discovered during fetal screening echocardiography in a 36-year-old Japanese woman at 23 weeks' gestation (GW). DAA was later found in the fetus during detailed echocardiography at 26 weeks' gestation. The female neonate, born at 38 weeks' gestation, weighed 2894 g and had 1- and 5-minute Apgar scores of 8 and 9, respectively, developed tachypnea, stridor, and wheezing soon after birth and was successfully operated on 10 hours after birth. Therefore, prenatal diagnosis of DAA contributed to early recovery in this case.
