产前超声心动图诊断胎儿肺动脉瓣狭窄与合并心内畸形的价值

Diagnostic Value of Fetal Pulmonary Valve Stenosis and Accompanied Intracardiac Malformations by Prenatal Echocardiography

目的探讨产前超声心动图在诊断胎儿肺动脉瓣狭窄的的诊断价值。方法回顾分析13例肺动脉瓣狭窄胎儿心脏声像学资料,总结分析胎儿正常和肺动脉瓣狭窄的声像图变化特点。结果共诊断肺动脉瓣狭窄13例,其中6例经生后超声心动图复查确诊。共有4例发现有合并其他心内畸形,以室间隔缺损最多。结论产前超声心动图在诊断胎儿肺动脉瓣狭窄和合并有无其他心内畸形上有很高的诊断价值。

Objective To discuss the diagnostic value of prenatal echocardiography in diagnosing fetal pulmonary valve stenosis. Methods Retrospective analysis was done based on cardiac ultrasonographic data of 13 cases of fetal pulmonary valve stenosis to sum-marize the characteristics of the ultrasonographic changes between normal fetus and fetal pulmonary stenosis. Results A total diagno-sis of pulmonary valve stenosis in 13 cases, 6 cases were confirmed by postnatal echocardiography and accompanied intracardiac malfor-mation were found in 4 cases, most with ventricular septal defect. Conclusion The prenatal echocardiography has clinical application value in diagnosis of fetal pulmonary stenosis and other intracardiac malformations.
