摘要
致痫灶的定位是选择外科手术方式的基础,也是决定手术效果的关键。我们对20例顽固性癫痫,术前根据病史,头皮脑电图(包括各种诱发试验)脑电地形图、颅内电极记录、CT,神经心理检查等进行综合评价,确定致痫灶。全组病例均手术治疗,随访6～18个月,发作完全消失16例,发作减少50%以上4例,无死亡。切除的致痫灶组织均行神经病理学检查,都发现有明显病理改变。
From July of 1989 to January of 1991,we performed surgical operations on 20 cases with intractable epilepsy.The preoperative localization of epileptogenic foci was based on a comprehensive evaluation of patients'seizure history,scalp EEG,topographic EEG display, cranial electrode recording,CT and neuropsychological investigations.Then,we selected an adequate surgical treatment,including 1 case of hemispherectomy,10 cases of anterior tem- poral lobectomy and 8 cases of extratemporal resection of the epileptogenic focus.Detected by electrocorticography and electrical stimulation monitoring,16 postoperative cases(80%) had seizure free and 4 cases(20%)had a more than 50% reduction in seizure frequency. The localization of epileptogenic foci,and surgical method and effect were discussed in detail. The key of surgical selection is to exactly localize epileptogenic foci with a comprehensive evaluation of various recordings and studies.The intracranial electrode recording is important for the localization of an epileptogenic focus.
