目的探讨法洛四联症胎儿超声心动图特征及最佳检查切面观.方法对11例经引产病理检查确诊为法洛四联症胎儿的超声声像图进行回顾性分析,总结法洛四联症各切面的声像图特征.结果以四腔观为起始扫查观,结合心室流出道观,三血管观及主动脉根部短轴观共诊断胎儿法洛四联症10例(10/11),漏诊1例,经引产后尸检证实为法洛四联症11例.四腔观上观察到室间隔缺损2例,其余9例未发现右心室肥厚;11例心室流出道观均观察到室间隔缺损,其中10例观察到主动脉骑跨;10例胎儿在三血管观及主动脉根部短轴观上均见到肺动脉狭窄及主动脉增宽,以上各观结合彩色多普勒检查有助于诊断.结论胎儿法洛四联症具有特征性声像图表现,在检查过程中注意在四腔观基础上联合心室流出道观、三血管观、主动脉根部短轴观有助于做出正确诊断.

Objective To investigate the echocardiographical features and optimal scan-planes of fetal tetralogy of Fallot(TOF).Methods The ultrasonogram of 11 fetuses diagnosed as TOF were analyzed retrospectively.And the echocardiographic findings of each conventional scan-plane were summarized. Results Ten fetuses were diagnosed as TOF with 1 missed case by the scan procedure from four-chamber plane,ventricular outlet palne, three vessels plane to aortic root short axis plane .All 11 fetuses were confirmed to be TOF by autopsy.Ventricular septal defect was found in 2 cases on four-chamber plane.Right ventricular hypertrophy was never observed in any of the 11 cases.On ventricular outlet plane,ventricular septal defect was found in 11 cases and overriding aorta in 10 cases.On three vessels and the aortic root short axis plane,10 cases was been found to have pulmonary stenosis and aortic broadening .These above-mentioned scan-planes combined with color Doppler were helpful in prenatal diagnosis of fetal TOF .Conclusions TOF in fetus has some characteristics on echocardiography .During examination,the four-chamber plane should be used in conjunction with the ventricular outlet ,three vessels,and the aortic root short axis planes to make a correct diagnosis.
