目的探讨室间隔完整-肺动脉闭锁的产前超声筛查诊断意义及临床价值。方法对20 000例胎儿采取胎儿心脏四腔心切面、左右心室流出道切面、三血管切面快速筛查胎儿心脏畸形,对疑有胎儿心脏畸形者叠加彩色多普勒超声观察血流,对异常者进行胎儿超声心动图复查确诊。结果产前共诊断室间隔完整-肺动脉闭锁7例。结论超声诊断胎儿室间隔完整-肺动脉闭锁,四腔心切面有很好的提示作用,结合其他切面及彩色多普勒超声观察血流,对诊断室间隔完整-肺动脉闭锁具有重要的临床价值,值得在广大的基层医院开展应用。
Objective To investigate the diagnostic value and clinical value of prenatal ultrasound screening of interventricular septum integrity-pulmonary atresia. Methods Fetal heart four-chamber heart-shaped section, left ventricle ventricular outflow tract section and left ventricle ventricular outflow tract section were collected from 20 000 fetuses. The fetal heart malformations were rapidly screened by three-vessel section. The color Doppler ultrasound was used to observe the blood flow in suspected fetal heart malformations. Fetal echocardiography review confirmed. Results prenatal diagnosis of complete ventricular septum - pulmonary atresia in 7 cases. Conclusion Ultrasound diagnosis of complete fetal compartment - pulmonary atresia, four-chamber heart section has a good reminder, combined with other sections and color Doppler ultrasound blood flow, diagnosis of complete ventricular septal integrity - pulmonary atresia has important clinical value, it is worth In the vast grassroots hospitals to carry out applications.
