Objective The study aimed to explore the association between the site of interictal epileptic discharges(IEDs)on postoperative electroencephalogram(EEG)and seizure recurrence after antiepileptic drug(AED)withdrawal.The study hypothesizes that the concordance of IED sites with surgical sites indicates incomplete resection of epileptic focus,while non-concordance of IED sites with surgical sites indicates postoperative changes or cortical stimulation.The former has a higher risk of seizure recurrence.Methods We retrospectively analyzed the postoperative EEG pattern of 182 consecutive children who underwent resection surgery.To identify the risk factors for seizure recurrence,we compared the attributes of seizure recurred and seizure-free groups by univariate and multivariate analyses.AED tapering was standardized,involving a 25% reduction in the dose of a single type of AED every 2 weeks,independent of the presurgical AED load.Results We attempted AED withdrawal in 116(63.7%)children.Twenty-eight(24.1%)children experienced seizure recurrence during or after AED withdrawal.A greater number of AEDs used at the time of surgery(p=0.005),incomplete resection(p=0.001),and presence of IED on postoperative EEG(p=0.011)are predictors of seizurerecurrence.Thecompletenessof resectionand seizure recurrence after AED withdrawal were related to the presence of IED on the EEG,but not to the concordance of IED with surgical sites.Conclusion For children with abnormal EEG,the decision to discontinue AED should be made more cautiously,regardless of the relative location of the discharge site and the surgical site. 展开更多
