【摘要】 目的探讨产前超声鉴别诊断技术在胎儿中枢神经系统畸形诊断中的应用。方法对经随访或引产证实217例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217例胎儿中枢神经系统畸形,其中无脑儿45例、水脑畸形4例、蛛网膜囊肿5例、Galen静脉瘤2例、脑室扩张78例(其中46例是中脑导水管狭窄)、脑膨出13例、Dandy-Walker综合征17例、开放性脊柱裂23例、前脑无裂畸形9例、胼胝体缺失5例、骶尾部畸胎瘤8例、脉络丛囊肿8例。结论掌握超声检查胎儿中枢神经系统畸形的鉴别诊断技术,即三个切面和12种分析思路,对产前超声检查极为重要。更多还原

【Abstract】 Objective To improve the clinical application of ultrasound differential diagnosis in abnormalities of fetus central nerve system.Methods Ultrasound imaging features in 217 cases of abnormalities in central nerve system confirmed by autopsy or follow-up were analyzed retrospectively.Results A total of 217 cases of anomaly in the central never system were examined prenatally by ultrasound and each showed typical imaging feature.Among these cases,there were 45 cases of anencephaly,4 cases of hydranencephaly,5 cases of arachnoid’s cyst,2 cases of aneurysm of the vein of Galen,78 cases of ventriculomegaly (among them 46 cases of aqueduct stenosis),13 cases of cephalocele,17 cases of Dandy-Walker complex,23 cases of spina bifida,9 cases of holoprosencephaly,5 cases of agenesis of the corpus callosum,8 cases of sacrococcygeal teratoma and 8 cases of choroid plexus cysts.Conclusion Application of ultrasound differential diagnosis by ultrasound for detection of abnormalities in fetus central nerve system(i.e.three sections and 12 clues),is extremely important.更多还原
