摘要
目的：作者对６０例脑部疾病患者Ｘ线刀治疗前后的脑电图（ＥＥＧ）、脑电地形图（ＢＥＡＭ）进行了观察和初步探讨。方法：６０例患者术前、术后做ＥＥＧ及ＢＥＡＭ检查，并与ＣＴ、ＭＲＩ、ＤＳＡ结果对照。结果：５３例术后３～４ｄ复查ＥＥＧ、ＢＥＡＭ，１２例（２２．６４％）无明显变化；４１例（７７．３５％）有不同程度的改变。结论：ＥＥＧ、ＢＥＡＭ对病灶定位与ＣＴ、ＭＲＩ、ＤＳＡ基本吻合；虽然ＥＥＧ、ＢＥＡＭ定位不如ＣＴ等方法精确，直观，但能反映出病灶对周围脑组织的影响范围及程度。
Objective:Preand postoperative EEG and BEAM were analysed in 60 patients with brain disease treated with Xnife.Methods:The EEG and BEAM were taken in all patients before operation. Postoperative reexamination were taken in 53 patients. Results:The abnormal rate of EEG and BEAM was higher in cerebral AVM and malignant brain tumor patients than in benign brain tumor patients; postoperative EEG and BEAM improved in 10 patients(24.39%), worsened in 16 patients(39.02).Conclusion:The authors considered that the abnormal rate of EEG and BEAM was related to the nature of intracranial lesions. Although the EEG and BEAM were not as accurate as CT and MRI for the localization of intracranial lesions, it could reflect the effect of intracranial lesions on its peripheral brain tissue and provide some information about the changes of electrical activity of brain after resection of intracranial lesion.
