Abstract: Premature constriction of fetal ductus arteriosus(DA)may cause stenosis or atresia of DA,resulting in right ventricular outflow tract obstruction and right heart failure or even death,which is usually caused by exposure to prostaglandin synthase inhibitors or intake of polyphenolic substances during pregnancy.Prenatal ultrasound can effectively and dynamically observe opening and constriction status of fetal DA,monitor blood flow using color Doppler,hence evaluate changes of cardiac function.The research progresses of prenatal ultrasound for premature constriction of fetal DA were reviewed in this article.
