系统超声检查对胎儿畸形的诊断分析

Diagnostic Value of Systematic Ultrasonic Examination for Fetal Anomaly

目的探讨系统超声对胎儿畸形的诊断价值。方法对32550例孕龄13～41周的胎儿在整个孕前检查中分别进行常规超声检查和系统超声检查,统计两种超声检查方法对胎儿畸形的检出率,与引产或分娩结果进行比对,分析系统超声检查的优势。结果在92例胎儿先天畸形中,常规超声检出胎儿畸形82例,检出率为89.13%;系统超声检出胎儿畸形89例,检出率为96.74%。常规超声检查漏诊10例,漏诊率为10.87%;系统超声检查漏诊3例,漏诊率为3.26%。系统超声检查对胎儿畸形的检出率明显高于常规超声检查(χ2=5.12,P<0.05)。结论对胎儿进行系统超声检查可提高胎儿畸形的检出率。

Objective To explore the diagnostic value of the systematic ultrasound screening for fetal anomaly. Methods All 32,550 fetus of gestational age from 13 to 41 weeks received both the conventional ultrasound and the systematic ultrasound examination. The detection rate of the two examniation were analysed. Results In 92 cases of fetal anomaly,the conventional ultrasound detected 82 cases of fetal anomaly with 89.13% of detection rate; the systematic ultrasound detected 89 cases of fetal anomaly with 96.74% of detection rate. The conventional ultrasound missed 10 cases,meanwhile the missed diagnostic rate were 10.87%.The systematic ultrasound missed 3 cases,and the missed diagnostic rate were 3.26%. The detection rate of fetal anomaly by the systematic ultrasound examination was higher than by the conventional ultrasound （Χ^2 = 5.1239〈0.05）. Conclusion The systematic ultrasound examination can increase the detection rate of fetal anomaly.
