胎儿法洛四联症的产前超声诊断

Prenatal Echocardiographic Diagnosis of Fetal Tetralogy of Fallot

目的:探讨胎儿法洛四联症的产前超声特征。方法:对12例经胎儿超声检查诊断为法洛四联症的超声资料进行回顾性分析,总结胎儿法洛四联症的声像图特点。结果:产前共诊断12例法洛四联症。胎儿法洛四联症的主要声像图特征是室间隔缺损、主动脉骑跨和肺动脉主动脉内径比异常。结论:超声心动图产前诊断胎儿法洛四联症具有重要的临床意义。胎儿典型法洛四联症的主要声像图特征是室间隔缺损、主动脉骑跨和肺动脉内径较主动脉内径窄,右室前壁增厚不明显。

Objective：The purpose of this study was to describe the antenatal ultrasonographic findings of fetuses with tetralogy of Fallot.Methods：The data of 12 fetuses diagnosed as tetralogy of Fallot by fetal echocardiography were reviewed and the abnormal echocardiographic features in various sonographic views were analyzed.Results：Twelve fetuses were confirmed to be tetralogy of Fallot by autopsy.The key echocardiographic features of tetralogy of Fallot were uniformly demonstrated to ventricular septal defect,overriding aorta and abnormal ratio of pulmonary artery to aorta.Conclusions：Fetal tetralogy of Fallot can be detected by echocardiography,it has important clinic value.The key echocardiographic features of tetralogy of Fallot were uniformly demonstrated to ventricular septal defect,overriding aorta,abnormal ratio of pulmonary artery to aorta and the abcence of the hypertrophy of the right ventricle.
