胎儿畸形超声漏诊原因分析

目的对孕妇中晚期胎儿发生畸形的超声诊断进行分析,同时对漏诊原因进行探讨,以便进一步提高胎儿畸形的检出率。方法对2011年2月～2012年7月来本院进行检查的32935例中晚期孕妇进行超声产前检查,同时回顾性分析检查结果。结果本院共检出胎儿畸形229例,其中,心血管系统52例,骨骼系统49例,消化系统44例,泌尿系统38例,神经系统36例,其他10例。胎儿畸形发生率为0.70%。221例产前检出,检出率为96.51%,8例漏诊,漏诊率为3.49%。结论诊断胎儿畸形的最好的办法是采用超声检查,对检查次数和时机适当的掌握,通过顺序连续、多切面和多角度观察,可使漏诊的概率降到最低。

Analysis of ultrasound misdiagnosis reasons of fetal malformation

Objective To analyze the ultrasound diagnosis of fetal malformation among women in mid-late pregnancy, and discuss the misdiagnosis reasons, in order to further improve the detection rate of fetal abnormalities. Methods Ultrasonic prenatal examine was carried out among 32 935 cases of women in mid-late pregnancy from February 2011 to July 2012 in our hospital. The examination results were analyzed retrospectively. Results Two hundred and twenty-nine cases were diagnosed with fetal malformation according to the examination in our hospital, among whom malformation of cardiovascular system in 52 cases, skeletal system in 49 cases, digestive system in 44 cases, urinary system in 38 cases, nervous system in 36 cases, and others in 10 cases. The fetal malformation rate was 0.70%. 221 cases were found by prenatal detection, the detection rate was 96.51%, 8 cases had misdiagnosed and the misdiagnosis rate was 3.49%. Conclusion Ultrasound examination is the best way for fetal malformation diagnosis. Controlling check time and opportunity appropriately, observing orderly, continuously and from different angles can make the probability of misdiagnosis reduce to the lowest.
