目的探讨胎儿心脏右室双出口的产前超声诊断的临床价值。方法应用超声四腔心切面、左右室流出道切面、三血管切面,检查胎儿心脏大血管有无异常。结果胎儿右室双出口15例,均伴发室间隔缺损,其中10例伴发室间隔缺损以外的其他心脏畸形,1例伴发心外畸形。发现异常者均经胎儿超声心动图检查确诊,并经胎儿染色体检查发现异常3例。结论胎儿右室双出口即为复杂性的大动脉畸形,超声可观察大动脉与心室的连接关系、血管的排列、主肺动脉的比例等有无异常改变,可作为诊断胎儿右室流出道病变的最佳方法,值得在产前应用并开展。
Objective To investigate the clinical value of prenatal ultrasound diagnosis of fetal right ventricle double outlet. Methods The four-chamber echocardiography, the left and right ventricular outflow tract sections, the three-vessel section were used to check whether there were any abnormalities in the fetal heart vessels. Results There were 15 cases of right ventricular double outlet in the fetus with ventricular septal defect. Among them, 10 cases had cardiac malformation other than ventricular septal defect and 1 case had extracardiac malformation. Found abnormalities were confirmed by fetal echocardiography, and fetal abnormalities found in 3 cases of chromosomal examination. Conclusions Double outlet of fetal right ventricle is a complex arteriolar malformation. Ultrasonography can observe the connection between aorta and ventricle, the arrangement of blood vessels and the ratio of the main pulmonary artery. It can be used as the best diagnosis of right ventricular outflow tract lesions Method, it is worth in prenatal application and carry out.
