【摘要】 目的 :探讨儿童脑电图纺锤波不对称与CT的关系及临床意义。方法 :将 2 5例儿童睡眠纺锤波不对称的脑电图结果与CT结果和临床表现进行对照分析。结果 :脑炎、脑萎缩、脑出血及脑挫伤的病例 ,脑电图纺锤波异常的部位与CT提示的病变部位基本一致 ;而外部性脑积水的病例CT表现是双侧额区或额顶区病变 ,纺锤波表现是一侧异常。结论 :纺锤波的一侧性或局灶性波幅下降提示脑内存在病变 ,是一种异常脑电图 ,且具有一定的定侧定位意义。一侧性或局灶性的纺锤波波幅降低与背景脑电活动的正常与否 ,对评估脑部疾病的转归和临床预后有一定的意义。更多还原

【Abstract】 Objective:To explore the relationship between the asymmetric spindle waves of childrens EEG and brain CT,and to explore the clinical significance of EEGs with asymmetric sleep spindle waves.Methods: A comparative analysis between the EEGs with asymmetric sleep spindle waves and brain CT and clinical manifestations was done in 25 children.Results:In patients with encephalitis,encephalatrophy,cerebral hemorrhage and cerebral contusion,the site of abnormal spindle waves was consistent with the focus site on brain CT.But in children with external hydrocephaly,CT showed focus on bilateral frontal or frontal-parrietal region,while the spindle waves showed a unilateral abnormality.Conclusions:The unilateral or focal decreace of spindle wave amplitude might suggest the existence of affection in the brain,it might be helpful in the lateralization,and be a kind of EEG abnormality.
