摘要
目的:探讨不同类型脑梗死患者动态脑电图(AEEG)变化的特点及对临床诊断的指导价值。方法:147例均应用24小时便携式磁带记录脑电图仪进行监测,并对比分析脑腔隙性梗死组与脑梗死组的AEEG异常程度。结果:AEEG总异常率为88.4%,腔隙性梗死组轻度异常60%,中、重度异常20%;脑梗死组轻度异常23%,中、重度异常77%,两组间存在显著差异(P<0.01)。腔隙性脑梗死组痫样波检出率3%,脑梗死组痫样波检出率25%,两组间也有显著性差异(P<0.01)。结论:脑腔隙性梗死以正常和轻度异常AEEG改变多见、痫样波出现率低;脑梗死以中、重度异常AEEG改变明显,痫样波出现率高。AEEG监测对脑梗死的诊断及病情变化均有重要价值。
Objective: To study the features of 24 - hour ambulatory electroencephalography (AEEG) and itsvalue 0f clinical diagnosis in patients with cerebral infarction. Method: One hundred and fourty - seven patients withcerebral infarction were monitored by AEEG, and the abnormal degrees of AEEG were compared between lacunar infarction group and cerebral infarction group. Results: The total abnormality rate of AEEG was 88%. In lacunar infarction group, the mild abnormalitality rate of AEEG was 60%, and moderate to severe abnormality rate was 20%, and thedetection rate of epileptiform wave was 3%. In cerebral infarction group, the mild abnormality of AEEG was 23% andmoderate to severe abnormality was 77%, and the detection rate of epileptiform wave was 25 %. There was a significantdifference between the lacunar infarction group and the cerebral infarction group. Conclusions: The abnormality ofAEEC was mild in lacunar infarction but severe in cerebral infarction. The positivity rate of epileptiform wave was lowin lacunar infarction but high in cerebral infarction. AEEG monitoring might be of very important value in the diagnosisand disease condition changes of cerebral infarction.
