【摘要】 胎儿动脉导管（DA）提前收缩可致管腔狭窄、闭锁，进而出现右心室流出道梗阻，引发右心衰竭甚至死亡;常由母体孕期应用前列腺素合成酶抑制剂类药物或摄入富含多酚类物质所致。产前超声可实时、动态观察胎儿DA开放及收缩状态，以彩色多普勒监测血流，进而评估心功能变化。本文围绕产前超声用于胎儿DA提前收缩研究进展进行综述。更多还原

【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.更多还原
