Abstract: This paper reported the ultrasonographic findings and pregnancy outcome in a case of fetal cervical aortic arch complicated by premature closure of ductus arteriosus. Ultrasound at 22+6weeks of gestation showed that the apex of fetal aortic arch reached the level of left clavicle, but no obvious abnormality in fetal intracardiac structure was found. Ultrasound examinations showed premature contraction of the fetal ductus arteriosus at 25+ 4 weeks of gestation and premature closure at 27+6 weeks. The pregnant woman was hospitalized due to the aggravation of fetal right heart failure at 34+1 gestational weeks and delivered by cesarean section at 34+3weeks. After 17 d of intensive care, the newborn was discharged in good condition. Ultrasound examination performed three months after birth showed that the aortic arch was at the level of left clavicle and the right cardiac system recovered well.
