对于脑肿瘤引起的临床上难治性癫痫,可以通过手术切除来治疗,既可以切除肿瘤,又能控制癫痫发作,有时可根据皮层脑电图所见来掌握手术切除范围。 本文对36例脑肿瘤合并癫痫患者进行术前及术后皮层脑电图监测,36例患者中,31例为低分级胶质瘤,4例为高分级胶质瘤,1例为畸胎瘤。分析记录到棘波的分布及发放频率。不管脑电表现如何,手术仅切除肿瘤,不额外切除正常脑组织。根据手术效果将患者分为两组。第一组为手术效果良好者(术后无癫痫发作或很少发作),第二组为手术效果较差者(术后癫痫仍有发
For clinically intractable epilepsy caused by brain tumors, it can be treated by surgical resection, which can not only remove the tumor but also control seizures. Sometimes, the scope of surgical resection can be grasped according to the findings of cortical electroencephalography. In this paper, preoperative and postoperative cortical EEG monitoring of 36 cases of brain tumors with epilepsy were performed. Of the 36 patients, 31 were low-grade gliomas, 4 were high-grade gliomas, and 1 was teratoma. . The distribution of the spikes and their frequency of release were recorded. Regardless of the performance of the brain, the surgery removes only the tumor and no additional removal of normal brain tissue occurs. Patients were divided into two groups according to the effect of surgery. The first group had good surgical results (no seizures or very few seizures after surgery), and the second group had poor surgical results (postoperative seizures still have hair
