摘要

目的：探讨磁源性影像对由海马硬化引起的颞叶癫痫术前致癫灶定位价值。方法：对16例海马硬化的病例术前实行脑磁图检查，并应用磁源性影像技术对致癫灶进行定位。结果：术后随访，按照南京军区总医院的评估标准：满意14例（87.5%）；显著改善1例（6.25%）；疗效差1例（6.25%）；总有效率93%。磁源性影像定位与视频脑电图的定位完全符合率为62.5%。结论：磁源性影像可以明确海马硬化患者癫痫源异常放电位置，可以用于术前致癫灶的定位。

Abstract

Objective: To evaluate the value of magnetic source imaging(MSI) in localization of the epileptogenic foci in temporal lobe epilepsy(TLE) caused by hippocampal sclerosis(HS). Methods: Sixteen patients with HS were evaluated with magnetoencephalography(MEG) before surgical excision, whose epileptogenic foci were located by MSI. Results: In the follow-up according to Nanjing Military Hospital, 14 patients(87.5%) received satisfying curative effect; 1 patient(6.25%) was partially relieved and 1 patient(6.25%) got poor effect, with a total effective rate of 93%. The concordance of MSI and Video-EEG in localization of epileptogenic foci was 62.5%. Conclusion: MSI could be a new valuable noninvasive functional neuroimaging technique for identification and delineation of epileptogenic foci in presurgical evaluation.
