妊娠中晚期胎儿轻度侧脑室增宽的超声诊断

目的:研究妊娠中晚期轻度侧脑室增宽胎儿的超声表现以及妊娠结局情况。方法:回顾性分析我院产前诊断的60例轻度侧脑室增宽的胎儿的声像图资料,均经引产或产后随访证实。结果:60例胎儿中,孤立性者42例,合并其它畸形的轻度侧脑室增宽者18例(1例NTD高风险,2例21-三体高风险)。30例单侧,30例双侧,脑室宽度为10.5~14.5 mm,平均宽度13.1 mm。22例终止妊娠,32例(包括2例双胎之一)产前超声侧脑室随访变为正常宽度,4例产后随访正常,2例产后超声和MRI证实为脑积水。结论:超声是诊断胎儿轻度侧脑室增宽的重要影像学手段,对指导妊娠结局有重要意义。

Sonographic Diagnosis of the Fetus with Mild Lateral Ventriculomegaly in Middle and Late Pregnancy

Objective:To investigate the ultrasonographic manifestations of mild lateral ventriculomegaly and the pregnancyoutcome in middle and late pregnancy.Methods:Clinical data of 60 fetuses diagnosed by ultrasound were analyzed retrospectively,which were confirmed by inducing abortion or by postpartum follow-up.Results:The total number of fetuses with isolated mild fetalventriculomegaly were 42 and fetuses with other malformations 18 (1 with high risk of NTD, 2 with high risk 21- trisomy), including 30cases with unilateal and 30 cases with bilateral mild fetal lateral ventriculomegaly. The average width of the lateral ventricles was 13.1mm(10.5~14.5 mm). The pregnancy was terminated in 22 pregnant women, and the lateral ventricles in 32 cases (2 cases were one of theof twins) were normal lately, and 4 cases were normal in postpartumfollow-up, and 2 cases were hydrocephalus confirmed by ultrasoundand MRI.Conclusion:Ultrasound is an important imaging means in diagnosing mild fetal lateral ventriculomegaly, and it has animportant effect for the outcome of pregnancy.
