50例脑动静脉畸形的脑电图分析

Analysis of EEG Changes in 50 Patients with Cerebral AVMs

本文报告了50例经脑血管造影证实的脑动静脉畸形的脑电图检查结果,发现所有患者均有脑电图变化。主要包括局限性异常,双侧半球不对称和普遍性异常。脑电图变化与畸形类型关系密切,作者认为应用脑电图去分析和判断脑血管畸形有一定临床意义。

The paper reported the resuits of EEG examination of cerebral arteriovenous malformations (AVM) in 50 patients since March 1986 to February 1990. There were 38 males and 12 females with the age ranged from 7 to 61 years (mean 33 years). The main manifestations were epilepsy (46.0%) and subarachnoid hemorrhage (34.0%). All of the patients had EEG changes including local 24 cases of abnormalities (48.0%), 19 cases of asymmetrical changes (38.0%) and 7 cases of diffuse adnormalities (14.0%). The results showed that there were the close relations between the type of AVM and the EEG changes. EEG chenge of AVM with fistula was mainly local abnormality (72.48%), while the EEG change of AVM with expanded capillary was mainly asymmetrical abnommality (81.25%). The author suggested that EEG examination is significant in analysis and diagnosis of cerebral AVM.
