Value of video EEG and MRI in the diagnosis of intractable epilepsy / 中国生化药物杂志

ABSTRACT

Objective To study the value of video EEG combined with MRI in the diagnosis of intractable epilepsy.Methods40 patients with intractable epilepsy treated in our hospital from 2013 to 2015 were selected as the subjects.In 40 patients, 26 patients with hippocampal sclerosis, 2 cases of patients with temporal lobe atrophy with cerebral dysplasia, 4 cases of patients with cerebral gray matter and macrogyria, 3 cases of vascular malformation, 1 cases of patients with intracerebral cyst, 2 cases of patients with glioma, 2 cases of patients with traumatic epilepsy.Retrospective of The clinical data of the selected patients were analyzed and the manifestations of epileptic foci were reflected by MRI, The use of video EEG was used to detect the status and source of EEG during epileptic seizure and epilepsy Analysis, combined with MRI scan and video EEG results, control surgery pathological changes, analysis of the results, draw conclusions.ResultsThere were 21 cases of the accurate location of interictal EEG.The accuracy was 52.5%, and the accuracy of the location of epileptogenic foci was about 40, and the accuracy was about 100%.The accuracy of MRI in the diagnosis of epileptic foci and related lesions was 35 cases, the accuracy rate was 87.5%, and the number of lesions was qualitative and accurate in the case of 30 cases, with an accuracy rate of 75%.ConclusionVideo EEG combined with MRI examination for drug refractory epilepsy diagnosis has important clinical value, can make a more accurate diagnosis of patients with epileptogenic foci, provide information for surgical treatment of intractable epilepsy patients, with further clinical promotion and application significance.
