摘要
目的探讨无病灶性顽固性癫手术前应用长程颅内电极埋置术定位致灶的适应证及可能将其省略的条件。方法回顾性分析82例术前MRI与CT证实无明显结构性病灶癫病人的手术治疗经验。根据我研究所制定的术前埋置电极适应证标准,采用电极埋置39例(埋置组),省略电极埋置43例(非埋置组)。术后随访1年以上,总结两组术前各项评估结果的特点,并比较手术预后效果。结果埋置组术后EngelⅠ与Ⅱ级25例(64.1%),非埋置组术后EngelⅠ与Ⅱ级20例(46.5%);两组比较,差异无统计学意义(P>0.05)。结论对于无病灶性顽固性癫病人,长程颅内电极监测是保障手术效果的一项重要手段。然而当发作间期异常放电焦点局限在单一脑叶并与发作起始点部位相一致时,如果此部位与发作症状学定位不悖,且在满足其他一定条件的前提下,少数病人可考虑省略颅内电极埋置而直接行致灶切除手术。
Objective To explore the indications and omission requirements for presurgical long-term intracranial electrode implantation(IEI) in patients with non-lesion intractable focal epilepsy.Methods Surgical experience with 82 epilepsy patients whose MRI and CT showed no structural lesion were reviewed respectively.Based on the indication criteria for omission of IEI,designed by our epilepsy center,39 underwent IEI and 43 had direct surgical resection without IEI.All patients were followed up more than 1 year.The...
