癫外科中最主要的问题是如何准确定位致灶[1]。目前,主要是通过症状学分析、影像学、长程视频脑电监测、脑磁图及正电子发射计算机断层显像(PET)等技术进行致灶定位。其中长程视频脑电监测是目前临床最为常用的定位方法。为探讨电极置入术的风险及并发症,近期,我们对2006年8月—2012年6月我科颅内皮质及深部电极置入术98例的临 The main problem in epilepsy is how to accurately locate induced focus [1]. At present, mainly through the symptomatology analysis, imaging, long-range video EEG monitoring, magnetoencephalography and positron emission computed tomography (PET) and other technologies induced focus positioning. One long-range video EEG monitoring is the most commonly used method of clinical positioning. In order to explore the risk and complications of electrode placement, recently, we have 98 cases of intracranial cortical and deep electrode placement in our department from August 2006 to June 2012
