目的探讨视频脑电图(VEEG)与影像学检查在继发性癫中的应用价值,并比较二者之间相互关系。方法对142例继发性癫患者完善了视频脑电图及头部MRI检查或CT检查,分析继发性癫患者发作间期、发作起始期视频脑电图提供的致灶定位信息,并与影像学结果进行比较,分析致灶与病理灶的关系。结果VEEG可为114例患者提供致灶的定位信息,继发性癫患者影像学检查不同的病理学改变可导致不同的临床发作类型;106例患者病理灶和致灶具有一致性,病理灶和致灶相反的有3例,8例提示双侧致灶的患者影像学检查却发现为单侧病灶。结论在继发性癫患者致灶的定位诊断中视频脑电图可使大部分患者获得致灶的定位信息;影像学检查对继发性癫患者的病理灶定位有重要意义;VEEG和影像学检查相结合可提高癫患者致灶定位的准确性。
Objective To explore the value of video-electroencephalography (EEG) and imaging in the detection of secondary epilepsy, and to compare the two. Methods A total of 142 cases of secondary epilepsy were improved video EEG and head MRI or CT examination of secondary epilepsy patients interictal and early onset episodes of video EEG positioning information provided by the stovepipe , And compared with the imaging results to analyze the relationship between lesions and pathological foci. Results VEEG provided information on the location of foci for 114 patients. Different pathological changes in the imaging of secondary epilepsy could lead to different types of clinical attack. The pathological lesions and foci of 106 patients were consistent, In contrast, there were 3 cases of pathological lesions and mucocutaneous lesions, and 8 cases of bilateral mucocutaneous lesions were found to be unilateral lesions. Conclusion Video EEG can make most of the patients get focal information of foci in the diagnosis of focal foci in patients with secondary epilepsy. Imaging examination plays an important role in the pathological foci of patients with secondary epilepsy. The combination of VEEG and imaging improves the accuracy of localization of the foci in patients with epilepsy.
