目的分析各类室间隔缺损(ventricular septal defect,VSD)产前超声特征,探讨产前超声检查对VSD的诊断价值和临床意义。方法对91例新生儿VSD的产前超声资料进行回顾分析,并对新生儿随访,比较产前诊断与产后诊断的符合率,分析各类VSD产前声像学特点,探讨产前超声检查对VSD的诊断价值和临床意义。结果本组VSD共91例,膜周部VSD 71例,肌部VSD 12例,双动脉瓣下VSD 6例,多发(2个部位以上)VSD 2例。漏诊7例,符合率92.3%(84/91)。结论超声心动图检查是产前发现VSD的重要手段,但双动脉瓣下VSD、肺动脉下VSD及小型VSD易漏诊。
Objective To analyze the prenatal echocardiographic features of various types of ventricular septal defects (VSD) and investigate the diagnostic value and clinical significance of prenatal echocardiography in VSD. Methods The prenatal ultrasound data of 91 neonates with VSD were retrospectively analyzed. The coincidence rates of prenatal diagnosis and postnatal diagnosis were compared between the two groups. The characteristics of prenatal sonography of all kinds of VSD were analyzed. The diagnostic value and clinical significance of VSD. Results There were 91 VSDs in this group. There were 71 cases of peritoneal VSD, 12 cases of VSD, 6 cases of VSD and 2 cases of multiple VSD. Misdiagnosis in 7 cases, with a rate of 92.3% (84/91). Conclusion Echocardiography is an important means of prenatal detection of VSD. However, it is easy to miss the diagnosis of VSD, VSD and VSD.
