【摘要】：目的探讨头皮动态脑电图(AEEG)在以癫痫为主要症状的老年颅内幕上肿瘤患者中的表现特点及临床价值。方法选择103例合并有癫痫症状的老年颅内幕上肿瘤患者临床资料,所有患者术前至少做1次AEEG检查,术中行皮层脑电图(ECo G)检查;比较两者异常放电波形特点、异常放电的病灶位置分布。结果所有患者术中异常放电阳性率为100.00%,AEEG显示有86例(83.50%)出现异常放电,其中ECo GⅠ型脑电波阳性率显著低于AEEG,ECo GⅤ型脑电波阳性率显著高于AEEG(P0.05),2种方法Ⅱ型、Ⅲ型、Ⅳ型脑电波阳性率比较差异无统计学意义(P0.05)。术前检查显示额叶、颞叶、顶叶间无异常放电阳性率、非局限型放电阳性率比较差异无统计学意义(P0.05),额叶局限型放电率显著高于颞叶、顶叶(P0.05)。术中额叶广泛性异常放电率显著高于颞叶和顶叶,额叶局限性异常放电率显著低于颞叶和顶叶(P0.05)。结论合并有癫痫症状的老年颅内幕上肿瘤患者AEEG检查异常放电阳性率低于ECo G,但AEEG与ECo G有部分一致性,术前AEEG检测能够为手术方案的制定提供一定依据。
[Abstract]:Objective to investigate the characteristics and clinical value of scalp dynamic electroencephalogram (AEEGG) in elderly patients with supratentorial tumors with epilepsy. Methods 103 patients with intracranial supratentorial tumors with epilepsy were selected. All patients were examined with AEEG at least once before operation and Ecoelectroencephalogram (ECoG) during operation, and the characteristics of abnormal discharge waveforms were compared. Results the positive rate of abnormal discharge in all patients was 100.00g / AEEG showing abnormal discharge in 86 cases (83.50%). The positive rate of ECo G 鈪，
