摘　　要：目的:探讨在产前常规超声检查中,侧脑室及小脑平面对胎儿中枢神经系统中线结构畸形的诊断价值。方法:从复旦大学附属妇产科医院3 921例畸形胎儿中选出97例中枢神经系统中线结构畸形胎儿,对其声像图特征进行回顾性分析。结果:产前超声诊断胎儿中枢神经系统中线结构畸形97例,其中脑膜脑膨出9例、无脑儿7例、脑膜膨出4例、透明隔腔增宽11例、完全型胼胝体缺失(ACC)16例、部分型ACC 15例、全前脑15例、蛛网膜下腔囊肿4例、Dandy-Walker畸形10例、Arnold-Chiari畸形Ⅱ型4例、Galen静脉瘤2例。结论:胎儿侧脑室平面及小脑平面的超声检查安全有效、方便快捷,是胎儿中枢神经系统畸形筛查最常用的切面,对胎儿中枢神经系统中线结构畸形检出率高。Objective: To evaluate the value of the lateral ventricle and cerebellum plane scanning in the diagnosis of fetal central nerve system(CNS) midline structure abnormalities. Methods: Ultrasound imaging features of 97 fetuses with fetal CNS midline structure abnormalities from 3 921 abnormal fetuses were analyzed retrospectively. Results: Among the 97 fetuses, there were 9 cases of encephalocele, 7 cases of anencephaly, 4 cases of meningocele, 11 cases of transparent septum widened, 16 cases of complete agenesis of the corpus callosum(ACC), 15 cases of partial ACC, 15 cases of holoprosencephaly, 4 cases of arachnoid cyst, 10 cases of Dandy-Walker malformation, 4 cases of malformation Arnold-Chiari type Ⅱ, and 2 cases of vein of Galen aneurysm malformation. Conclusion: The lateral ventricle and cerebellum plane scanning is a safe, liable, practical and quick method to diagnose the fetal CNS midline structure abnormalities.
