超声诊断胎儿畸形50例分析

Analysis of 50 Cases of Embryo Anamorphosis Diagnosed Via Ultrasongraphy

本文对2218例中、晚期妊娠超声监测中筛检出胎儿畸形50例进行分析。病例均经引产、自然分娩证实,部分经尸体解剖证实。结果表明胎儿畸形检出率为2.3%。单一畸形占88%,复合畸形占12%。各类畸形中以中枢神经系统畸形所占比例最高(58%)。本文认为掌握好胎儿脊柱背侧中线的神经管畸形及前腹中线的裂腹畸形的超声诊断,对提高胎儿畸形检出率,对优生医学极有价值。超声诊断方法简便,无创,可重复检查,动态观察,是检测胎儿畸形的首选方法。

This medical article analysed 50 cases of embryo anamorphosis that were sifted from 2218 cases during the middle or later period of pregnancy by ultrasongraphic inspection.The results showed that the defection rate of embryo anamorphosis was 2.3% .Single and complex anamorphosis accounted for 88% ,for 12% .respectively among all the kinds of anamorphosis,central nervous system anamorphosis had the greatest proportion (58%) .We believe that it is of great value for increasing the detection rate of embryo anamorphosis and for eugenics to master well the ultrasongraphic diagnosis of the flaw in nerve tube of the embryo on the dorsal middel line of spine. Ultrasongraphic examination is easy to conduct, noninvasive and is capable of repealed detection and dynamic observation.This method is really the first choice for embryo anarnorpnasis detection.
