产前超声检查对胎儿畸形的诊断效能分析

Analysis of Diagnostic Efficacy of prenatal Ultrasound Examination for Fetal Malformation

目的探讨产前超声检查对胎儿畸形的诊断效能。方法回顾性分析产检的4542例孕妇的临床资料,畸形胎儿经随访结果证实。记录胎儿畸形发生率、超声诊断准确性以及各系统器官畸形发生率,观察胎儿畸形检出时间分布情况。结果4542例孕妇中畸形胎儿有37例,畸形率0.81%,其中超声检查出胎儿畸形35例,检出率为0.77%,超声诊断准确率为94.59%;主要畸形存在于中枢神经系统13例和心血管系统11例;中枢神经系统畸形检出时间孕周为(20.81±2.37)周,四肢骨骼系统畸形检出时间孕周为(23.41±1.98)周,较其他系统检出时间早。结论胎儿畸形可在产前通过超声进行诊断,超声在产科检查中有较高的应用价值。

Objective To investigate the diagnostic efficacy of prenatal ultrasound examination for fetal malformation.Methods The clinical data of 4542 pregnant women who were examined in our hospital were retrospectively analyzed.Deformed fetus confirmed by follow-up results.The incidence of fetal malformation,the accuracy of ultrasound diagnosis and the incidence of organ malformation in each system were recorded,and the distribution of fetal malformation time was observed.Results Among the 4542 pregnant women,there were 37 cases of malformed fetuses with a deformity rate of 0.81%.Among them,35 cases were detected by ultrasound,and the detection rate was 0.77%.The accuracy of ultrasound diagnosis was 94.59%(35/37).The main malformations existed in the central nervous system(13 cases,35.14%)and the cardiovascular system(11 cases,29.73%).The detection time of central nervous system malformation was(20.81±2.37)weeks and limb skeletal system malformation(23.41±1.98)weeks,earlier than other systems.Conclusion Fetal malformation can be diagnosed by ultrasound before delivery.Ultrasound has a high application value in obstetric examination.
