目的:探讨超声心动图在产前诊断胎儿先天性心脏病诊断中的临床价值。方法:应用超声心动图对大于孕18周的孕妇进行胎儿系统筛查。观察胎儿腹围大血管位置平面、四腔心切面、左右室流出道切面、三血管切面、主动脉弓切面、动脉导管弓切面、上下腔静脉长轴切面二维声像图,观察心脏大小、结构、大血管的位置、走行等,并结合彩色多普勒进行分析。结果:发现胎儿先天性心脏病19例。其中单心室、单心房并共同动脉干3例;左心发育不良2例;右心发育不良2例;右室双出口1例;完全性心内膜垫缺损3例;法乐四联征1例;室间隔缺损3例;完全性大动脉转位1例,矫正型大动脉转位1例;主动脉弓离断2例。结论:超声心动图对产前诊断胎儿先天性心脏病具有很高的价值,是首选诊断方法。
Objective: To investigate the clinical value of echocardiography in the diagnosis of fetal congenital heart disease. Methods: Echocardiography was performed on fetuses of pregnant women larger than 18 weeks pregnant. Observe the fetal abdominal ventricular large vessel position plane, four chamber heart section, left and right ventricular outflow tract section, three vessel section, aortic arch section, arterial catheter arch section, superior vena cava long axis view two-dimensional sonography, observed heart size, structure, The location of large blood vessels, walking, etc., combined with color Doppler analysis. Results: Fetal congenital heart disease found in 19 cases. Among them, there were 3 cases of single ventricle and single atrium with common arterial trunk, 2 cases of left heart dysplasia, 2 cases of right heart dysplasia, 1 case of right ventricular double outlet, 3 cases of complete endocardial cushion defect, Cases; ventricular septal defect in 3 cases; complete aortic transposition in 1 case, correction of major artery transposition in 1 case; aortic arch in 2 cases. Conclusion: Echocardiography is of high value in prenatal diagnosis of fetal congenital heart disease and is the first choice of diagnostic method.
