ObjectivesTo explore the preoperative assessment method, operative approach and post-operative effect of intractable epilepsy.MethodsOne hundred and twenty five intractable epilepsy patients (85 males and 40 females) from Wuhan Brain Hospital during June 2009 to June 2017 were collected in this study. Their age ranged from 1 to 70 years old, with disease course of 1 ~ 32 years. All the patients underwent VEEG monitoring and MRI examination before operation, and MRS was performed when necessary. Some patients also received psychological assessment. According to the result of VEEG and MRI results, all the patients underwent operations under ECoG monitoring . The surgery effect was followed-up for more than 1 year.ResultsThe post-operative follow-up showed that satisfactory result was achieved in 50 cases, remarkable improvement in 29 cases, good effect in 23 cases, bad effect in 19 cases, and no improvement in 4 cases. The total effective rate of epilepsy surgery was 81.6%, and excellent rate was 41.6%. The effective rate was 81.3% in 80 cases of epileptogenic focus epileptic lesion resection, 87.5% in 40 cases of anterior temporal lobectomy (ATL), and 100% in 3 cases of functional hemispherectomy was, and good effect in the cases of pure cortical coagulation and VNS.ConclusionsThe surgical effects of ATL, epileptogenic focus resection and functional hemispherectomy are better than that of pure corpus callosotomy, multiple subpial transaction (MST), multiple subdural transversely fibrinectomy, VNS or cortical coagulation. So epileptogenic focus should be accurately located preoperatively, and it is better to choose resection operation in order to increase the surgical effect of intractable epilepsy.
ObjectiveTo explore the clinical features and surgical treatment effects of the temporal lobe epilepsy with hippocampal sclerosis.MethodsForty two patients diagnosed as temporal lobe epilepsy with hippocampal sclerosis and underwent protemporal lobectomy in Wuhan Brain Hospital from Jan. 2012 to Dec. 2018 were collected, which included 30 males and 12 females, with the age between 9 to 60 years. Their disease duration ranged from 3 to 10 years. The clinical manifestations showed complex partial seizure in 18 cases, partial-secondary –generalized seizure in 4 cases, and generalized tonic-clonic seizure in 20 cases. Based on their results of clinical manifestations, combined with MRI and VEEG results, all the patients underwent anterior temporal lobectomy (including the most parts of the hippocampus and amydala).ResultsThe postoperative pathology confirmed the diagnosis of hippocampal sclerosis. The follow-up of more than 1 year showed seizure-free in 38 cases, and significant improvement in 4 cases.ConclusionsTo the patients of temporal lobe epilepsy with hippocampal sclerosis, anterior temporal lobectomy should be performed (including the most parts of the hippocampus and amydala) if the VEEG monitoring results show that there are epileptic discharges in the ipsilateral temporal lobe. And the postoperative curative result is satisfactory.
