【摘要】 目的观察长程脑电监测对幕上开颅手术后癫痫的诊断价值。方法选择260例幕上占位性病灶患者,术前2~3 d、术后7~10 d和1~3个月分别长程脑电检查。结果①长程脑电术前、术后7~10 d和1~3个月异常率分别为88.1%、97.7%、77.7%。②术前无癫痫发作者,术后新发癫痫17例,提示手术对大脑皮质的损害,可能增加致痫机会。结论长程脑电对幕上占位性病灶术前术后的监测,能显示病灶及手术对脑机能的影响,有助于术后癫痫的诊断。更多还原

【Abstract】 Objective To assess the diagnostic value of long time EEG monitoring on epilepsy following supratentorial surgery.Methods Long time EEG was performed 2-3 d before operation,7-10 d and 1-3 months after operation in 260 cases with supratentorial mass lesions.All patients,174 male and 86 female,aged 18 to 60 years old,were hospitalized in our hospital from Mar 2001 to Oct 2003,among whom 112 with the history of epileptic seizure and 148 without.Results The abnormal rate in long time EEG before operation,7-10 d and 1-3 months after operation was 88.1%,97.7% and 77.7% respectively.Seventeen cases without the history of epileptic seizure developed postoperative epilepsy,indicating the supratentorial surgery impairs the cerebral cortex and brings more epileptic seizure.Conclusion Cortical damages caused by the surgical lesions may increase the incidence of epilepsy.The preoperative and postoperative long time EEG monitoring on the patients with supratentorial space occupying lesions can detect the changes of brain function and conduce to predict the postoperative epilepsy.更多还原
