186例胎儿出生缺陷产前超声诊断分析

目的探讨产前超声对出生缺陷的诊断价值。方法回顾性分析2005-2010年间诊断为出生缺陷的病例,观察超声诊断检出率及缺陷类型等。结果共发生出生缺陷186例,超声诊断检出率为60.75%。其中单发畸形检出率为55.5%,多发畸形检出率为84.8%,合并羊水异常占22%。结论产前超声诊断多发畸形检出率相对较高,对于诊断胎儿结构异常有着非常重要的临床价值。但是目前的超声筛查也具有一定的局限性。通过合理选择检查时机,采用局部放大及提高频率,可有效地提高超声诊断检出率。

Analysis on the prenatal ultrasound of 186 fetuses with birth defects

Objective To investigate the value of prenatal ultrasound in the diagnosis of birth defects. Methods We have retrospectively analyzed the clinical data of 186 fetuses with birth defects from 2005 to 2010. The detection rate of ultrasound screening and the types of detects were observed. Results The detection rate of ultrasound was 60.75%, which is 55.5% for single monstrous and 84.8% for multiple monstrous. 22% of the fetuses with birth defects were found to be complicated with abnormal amniotic fluid. Conclusion The detection rate of ultrasound screening in multiple monstrous diagnosis was much higher, which has great clinical significance in the diagnosis of fetal malformation. However there were still some limitations, which could be compensated by selecting the premium time for examination and applying partial enlarges.
