摘　　要：目的探讨头皮脑电图(EEG)在功能性大脑半球切除术中的应用价值。方法回顾性分析8例药物难治性癫痫行功能性大脑半球切除术的患者,分析病因与术后转归相关性,着重分析术前头皮EEG背景活动、间歇期放电、发作起始及术后EEG特征。结果 8例患者以获得性病因为主。术前头皮EEG背景活动多表现为慢波增多,患侧显著;发作间歇期双侧半球呈现多脑区放电特征;发作起始EEG改变多为弥漫性改变;术后复查EEG,1个月内以双侧放电居多,半年以上复查以患侧放电居多。结论头皮EEG作为一种简便易行的检查手段,在功能性大脑半球切除术术前评估、术后随访中起到重要作用。Objective： To investigate the role of scalp EEG in patients underwent functional hemispherectomy. Methods The clinical data of 8 patients with catastrophic epilepsy who underwent functional hemispherectomy were analyzed retrospectively. The etiologies,all pre-and postoperative scalp EEGs were analyzed,including EEG background,both interictal and ictal EEG modality. Results Of 8 patients,the most etiologies were acquired ones. About the EEGs,slow waves of background activity were mostly observed in both hemispheres,interictal EEGs were recorded in multi-focally brain,ictal EEGs were mostly characterized by diffused discharge,postoperative EEGs were recorded respectively in 1 month and half one year later,the short-term EEGs were bilaterally discharged,the long-term ones ipsilaterally. Conclusion As a simple means of inspection,scalp EEG played a great part in preoperative evaluation and postoperative follow-up.
