摘要
目的初步探索在颅内有创脑电监测下进行难治性枕叶癫痫外科治疗的效果。方法回顾性分析8例应用有创脑电监测的枕叶癫痫病例,所有病例均经过磁共振(MRI)、正电子发射断层扫描(PET)、头皮视频脑电监测(VEEG)等术前评估,初步判断癫痫起源在枕叶,再应用有创脑电监测,进一步明确致痫区的位置和范围,2期行致痫区手术切除。结果术后无死亡及严重并发症,其中1例视野缺损稍有加重。6例患者术后随访超过1 a,2例患者随访超过半年,其中6例术后无癫痫发作,2例发作次数明显减少。结论颅内电极长程脑电监测对于明确致痫区及视觉皮层、确定并精确切除致痫区具有重要意义,在其辅助下难治性枕叶癫痫的外科疗效提高,并发症减少。
Objective To investigate the effect of surgical treatment using intracranial video electroencephalogram（iVEEG） in patients with intractable occipital lobe epilepsy.Methods The clinical data for eight patients undergoing implantation of intractable epilepsy were retrospectively reviewed.All patients underwent MRI,position emission tomography（PET） and scalp video electroencephalogram（VEEG） that indicated occipital lobe epilepsy,then iVEEG that contributed to confirm the location of seizure foci and the lesionectomy were performed.Results No severe complication occurred due to the implantation,only one patient＇s field of vision was damaged lightly.Six patients were seizure-free,two patients＇ seizure frequencies reduced significantly.Conclusion iVEEG is considerable for identification of seizure foci and visual cortex.The therapeutic effect of operations to intractable occipital lobe epilepsy would improve with its help,and the complication would reduce simultaneously.
