摘要
目的探讨产前常规超声检查对胎儿中枢神经系统畸形的临床应用价值。方法对143例经引产或随访证实的胎儿中枢神经系统畸形的声像图特征进行回顾性分析。结果产前超声诊断143例,其中无脑儿35例、水脑畸形1例、蛛网膜囊肿3例、Galen静脉瘤1例、脑室扩张55例、脑膨出9例、Dandy-Walker综合征11例、开放性脊柱裂15例、前脑无裂畸形5例、胼胝体缺失2例、骶尾部畸胎瘤3例和脉络丛囊肿3例。结论超声检查安全有效、方便快捷,对胎儿中枢神经系统畸形确诊率高,是产前筛查胎儿中枢神经系统畸形的可靠方法。
Objective To evaluate the clinical application of ultrasound examination as a routine scanning method for fetal central nerve system abnormalities. Methods Ultrasound imaging features of 143 fetus with fetal central nerve system abnormalities confirmed by autopsy or follow-up were analyzed retrospectively. Results One hundred and forty-three fetus with fetal central nerve system abnormalities were examined prenatally by ultrasound and each showed typical imaging feature. Among these cases, there were 35 cases of anencephaly, 1 case of hydranencephaly, 3 cases of arachnoid＇s cyst, 1 case of aneurysm of the vein of Galen, 55 cases of ventriculomegaly （among them 38 cases of aqueduct stenosis）, 9 cases of ceph- alocele, 11 cases of Dandy-Walker complex, 15 cases of spina bifida, 5 cases of holoprosencephaly, 2 cases of agenesis of the corpus callosum, 3 cases of sacrococcygeal teratoma and 3 cases of choroid plexus cysts. Conclusion Ultrasound examination is a safe, liable, practical and quick method to screen fetal central nerve system abnormalities with a high detection rate.
