发作期录像脑电监测在15例难治性颞叶癫痫患者术前定位中的价值

目的 探讨发作期录像脑电监测（IVEEG）在难治性非病变性颞叶癫痫（TLE）致痫源术前定位中的价值。方法 对15例药物难治性TLE患者术前定位资料及术后随诊情况进行分析。结果 所有患者在行长时间IVEEG监测中均捕获到临床发作。在15例患者中，有13例IVEEG显示出一侧起源的局灶爆发性节律性电活动，该放电侧均与最终切除侧相一致，且有11例患者术后效果较好。结论 IVEEG监测不仅有助于明确诊断及发作类型，更为重要的是对于大多数难治性非病变性TLE患者可提供较可靠的致痫源定侧信息。

Ictal video-electroencephalography monitoring in presurgical evaluation for intractable temporal lobe epilepsy in 15 cases

Objective To assess the value of ictal video-electroencephalography monitoring (IVEEG) in presurgical evaluation for medically intractable nonlesional temporal lobe epilepsy(TLE). Methods The data of presurgical evaluation and postsurgical follow-up from 15 patients with intractable TLE were retrospectively analyzed.Results In this selected patients group, all 15 patients manifested clinically seizures during long term VEEG monitoring, with initial rhythmic activity from one side of temporal lobe in 13 cases. Of these 13 patients, the side of initial ictal focal pattern was concordant with the side of anterior temporal lobectomy or selective amygdalohippocampectomy in all cases and excellent postsurgical outcome were attained in 11 patients.Conclusion IVEEG monitoring may not only help to confirm the diagnosis and seizure type(s),but also more important to correctly localize the side of epileptogenic region in most patients with intractable TLE.
