脑梗死继发癫痫84例脑电图分析

Electroencephalogram analysis on 84 cases of secondary epilepsy after cerebral infarction

目的：分析脑梗死继发癫痫的脑电图特点。方法选择2013年7月-2014年7月神经内科收治的84例脑梗死继发癫痫患者,分析患者脑电图的变化。结果早期发作的检出率为75.0%,迟发性发作的检出率为83.3%,差异有统计学意义（字2=70.16,P〈0.05）。单纯部分性发作54例,复杂部分性发作12例,全面性发作18例。脑《梗死52例,基底节区梗死12例,腔隙性梗死8例,多发性梗死12例。脑《梗死灶脑电图异常检出率为88.5%,基底节区和多发性梗死异常检出率为66.7%,差异有统计学意义（字2=79.45,P〈0.05）。结论脑电图对脑梗死继发癫痫后的诊断及癫痫灶定位有一定的临床价值。

Objective To analyze the features of electroencephalogram（EEG）with secondary epilepsy after cerebral in-farction. Methods 84 patients with secondary epilepsy after cerebral infarction in neurology department from July 2013 to July 2014 were selected,EEG change of patient was analyzed. Results Early onset detection rate was 75.0%,the de-tection rate of delayed onset was 83.3%,with statistical difference （χ2=70.16,P〈0.05）.54 patients were simple partial seizures,12 patients were complex partialcases,18 patients were general seizure.52 patients were lobar infarct,12 pa-tients were basal ganglia infarction,8 patients were lacunar infarction,12 patients were multiple infarction.EEG abnor-mality detection rate of lobar infarct was 88.5%,abnormal detection rate of basal ganglia and multiple infarct was 66.7%,with statistical difference（χ2=79.45,P〈0.05）. Conclusion EEG is valuable in diagnosis and position of secondary epilepsy after cerebral infarction.
