超声心动图在诊断胎儿法洛四联症中的价值

Value of Echocardiography in the Diagnosis of Fetal Tetralogy of Fallot

目的:研究分析超声心动图在诊断胎儿法洛四联症中(TOF)的价值。方法:收集某院2011年9月~2017年10月经超声心动图诊断证实为TOF的24例病例资料进行回顾分析,给予产前超声心动图检查和引产后病理解剖、胎儿产后超声心动图检查,观察超声心动图的产前诊断准确率,并总结TOF胎儿超声检查表现特点。结果:引产后病理解剖和胎儿产后1周超声心动图检查TOF胎儿确诊率为100.00%(24/24),产前超声心动图确诊率为95.83%(23/24),准确率对比差异无统计学意义(P>0.05);胎儿TOF病例切面扫查表现为:四腔心切面出现室间隔缺损占比16.67%(4/24),左室流出道切面出现室间隔缺损且间隔断端回声有增强、主动脉骑跨占比95.83%(23/24),右室流出道切面出现肺动脉狭窄占比91.67%(22/24),三血管切面出现动脉内径小于主动脉内径情况占比95.83%(23/24)。结论:超声心动图对TOF胎儿的产前确诊率较高,有应用价值。

Objective：To study the value of echocardiography in the diagnosis of fetal tetralogy of fallot（TOF）.Methods：The data of 24 cases of TOF confirmed by echocardiography from September 2011 to October 2017 were collected and analyzed retrospectively Antepartum echocardiography,postpartum fetal echocardiography and postpartum fetal echocardiography were performed to observe the accuracy of prenatal diagnosis,and to summarize the features of TOF fetal ultrasound examination.Results：Pathological anatomy after induced labor and echocardiographic examination of fetal postpartum 1 week after delivery,the fetal diagnosis rate of TOF was 100.00%（24/24）,while that of prenatal echocardiography was 95.83%（23/24）.There was no significant difference in accuracy（P〉0.05）.The scanning findings of fetal TOF cases were as follows：ventricular septal defect（VSD）appeared on the quadrilateral central plane of the septal defect（16.67%,4/24）,ventricular septal defect appeared on the section of left ventricular outflow tract with enhanced echo at the septal end and aortic straddle（95.83%,23/24）,pulmonary artery stenosis appeared on the section of the right ventricular outflow tract（91.67%,22/24）,and the internal diameter of the artery was smaller than that of the aorta on the triangulation plane（95.83%,23/24）.Conclusion：Echocardiography has high diagnostic rate and application value for TOF fetus.
