摘要
目的 探讨超声诊断婴儿外部性脑积水 (EH )的临床价值。方法 应用超声对 48例对象研究 ,正常组 3 0例 ,经CT诊断为EH的 18例患儿 ,进行对比研究。结果 正常组蛛网膜下腔 2 .5mm大脑半球间裂 3mm ,EH组蛛网膜下腔 3～8mm ,大脑半球间裂 4～ 10mm。两项指标 ,患儿组均高于正常组。结论 由于超声能清晰显示婴儿颅内组织结构 ,应用方便 ,易于观察蛛网膜下腔及大脑半球间裂的变化 ,使超声检查成为诊断EH的一种准确、快速的方法。
Objective To discuss the clinical value of diagnosing external hydrocephalus' by ultrasonography.Methods The results of ultrasonography in 48 children with external hydrocephalus confirmed by head CT were compared with 30 normal subjects. Results Subarachnoid cavity was 2.5mm and the space between cerebral hemispheres was 3mm in the healthy children. Subarachnoid cavity measured 3-8mm and the space between cerebral hemispheres measured 4-10mm in patients with External Hydrocephalus, in which were dilated than in the healthy subjects. Conclusion Ultrasonography is an useful and convenient technique for diagnosing external hydrocephalus because of its capability of visualizing the encephalic structure, evaluating the variation in the subarachnoid cavity as well as the space between cerebral hemispheres.
