目的评价胎儿超声心动图对16孕周之前先天性心脏病风险胎儿妊娠处理的临床作用。方法222例高危孕妇(230胎儿)于第14+1孕周中期连续进行了经腹部胎儿超声心动图检查。正常扫描标准为正常的连续节段分析法、对称性四腔切面、正常半月瓣、心室流出道、动脉导管与动脉弓。早期检查与中期妊娠中期超声心动图检查进行了对比,所有病例均有死亡及活产儿随访资料。结果在高危妊娠中早期胎儿超声心动图诊断符合率占96%。结论需要对早期胎儿超声心动图进行综合学科研究才能获得准确诊断。
Objective To evaluate the clinical effect of fetal echocardiography on fetal pregnancy at risk of congenital heart disease before 16 weeks gestation. Methods Totally 222 high-risk pregnant women (230 fetuses) were examined by fetal fetal echocardiography consecutively in the mid-14th gestational week. Normal scan criteria were normal sequential segment analysis, symmetrical four-chamber view, normal semilunar valve, ventricular outflow tract, ductus arteriosus and aortic arch. Early screening and mid-term gestational echocardiography were compared, with all cases of death and live-fetus follow-up data. Results The coincidence rate of fetal echocardiography was 96% in early stage of high-risk pregnancy. Conclusion Comprehensive studies of early fetal echocardiography are needed to obtain accurate diagnosis.
