目的评价产前超声心动图在诊断胎儿不合并室间隔缺损的肺动脉瓣闭锁中的应用价值。方法回顾性分析2013-2014年在唐山市妇幼保健院进行产前超声检查并诊断的不合并室间隔缺损的肺动脉瓣闭锁胎儿9例,分析其超声心动图共同特点、产前超声诊断符合率及其合并症。结果产前超声心动图诊断胎儿不合并室间隔缺损的肺动脉瓣闭锁病例共9例,其中8例经引产后证实,1例漏诊,产前超声心动图符合率为88.89%。超声心动图共同特点是均伴有大量三尖瓣反流,3例伴有单脐动脉,1例伴有持续性右脐静脉,6例伴有羊水多。结论产前超声心动图在诊断胎儿不合并室间隔缺损的肺动脉瓣闭锁中具有重要的应用价值,三血管气管切面可以作为诊断的重要切面。
Objective To evaluate the value of prenatal echocardiography in the diagnosis of pulmonary valve atresia with fetal uncomplicated ventricular septal defect. Methods A retrospective analysis of 9 fetuses with unilateral ventricular septal defect diagnosed by prenatal ultrasound in Tangshan Municipal Maternal and Child Health Hospital from 2013 to 2014 was performed. The common features of echocardiography, coincidence rate of prenatal ultrasound diagnosis, Its complications. Results In prenatal echocardiography, 9 cases of pulmonary atresia with fetal ventricular septal defect were diagnosed. Among them, 8 cases were confirmed by induction of labor and 1 case missed diagnosis. The coincidence rate of prenatal echocardiography was 88.89%. Common features of echocardiography are associated with a large number of tricuspid regurgitation, 3 cases with single umbilical artery, 1 case with persistent right umbilical vein, 6 cases associated with amniotic fluid and more. Conclusion Prenatal echocardiography has an important value in the diagnosis of pulmonary valve atresia with fetal uncomplicated ventricular septal defect. The trigeminal tracheal section can be used as an important section of diagnosis.
