【摘要】：目的探讨视频脑电图(V-EEG)和磁共振成像(MRI)对继发性癫痫的诊断价值。方法收集157例完善了V-EEG及头部MRI检查的继发性癫痫患者的临床资料。对患者的V-EEG、MRI检出率行相关分析,对发作形式、病因等作对比,并比较致痫灶和病例灶之间的关系,分析V-EEG、MRI对继发性癫痫的临床诊断价值。结果患者MRI结果阳性时,V-EEG检出率为93.38%;MRI结果阴性时V-EEG检出率为76.19%;两者差异有统计学意义(P0.05)。157例患者中,V-EEG监测出异常痫样放电的患者有143例,其中颅内感染、颅内出血、颅内肿瘤V-EEG检查阳性率分别为95.24%、92.31%、95.00%,明显高于其他病因的检出率。157例继发性癫痫患者中,85例患者病理灶和致痫灶具有一致性,两者符合率为54.14%。V-EEG诊断继发性癫痫的灵敏度、特异度、准确度均高于MRI,差异有统计学意义(P0.05)。结论继发性癫痫患者V-EEG、MRI检查结果呈正相关;V-EEG检查对继发性癫痫有很高的诊断价值,颅内感染、颅内出血、颅内肿瘤等病因V-EEG检出率较高;MRI检查是继发性癫痫病因病因诊断的重要手段;致痫灶和病理灶常大部分具有一致性,将V-EEG和MRI相结合可提高继发性癫痫患者定位诊断的准确性。
[Abstract]:Objective to investigate the diagnostic value of video electroencephalogram (V-EEG) and magnetic resonance imaging (MRI) in secondary epilepsy. Methods the clinical data of 157 cases of secondary epilepsy with V-EEG and head MRI were collected. The detection rate of V-EEGG MRI in patients was analyzed by correlation analysis, seizure form and etiology were compared, and the relationship between epileptogenic foci and case foci was compared, and the clinical value of V-EEGG MRI in the diagnosis of secondary epilepsy was analyzed. Results the detection rate of V-EEG was 76.19 when MRI was positive and V-EEG was negative. There were significant differences between the two groups (P0.05). Of the 157 patients, 143 had abnormal epileptiform discharges detected by V-EEG. The positive rates of V-EEG were 95.24% in patients with intracranial infection, intracranial hemorrhage and intracranial tumors, respectively. 92.31 and 95.00 were significantly higher than the detectable rate of other causes. Of the 157 patients with secondary epilepsy, 85 patients had the same pathological focus and epileptic stove. The coincidence rate between them was the sensitivity of 54.14%.V-EEG in the diagnosis of secondary epilepsy. Specificity and accuracy were significantly higher than those of MRI, (P0.05). Conclusion there is a positive correlation between the results of V-EEGG MRI and V-EEG in the diagnosis of secondary epilepsy, the detection rate of V-EEG is higher in patients with intracranial infection, intracranial hemorrhage, intracranial tumor, and so on. MRI is an important method in the diagnosis of secondary epilepsy, and the epileptogenic foci and pathological foci are usually consistent. The combination of V-EEG and MRI can improve the accuracy of location diagnosis in patients with secondary epilepsy.
