目的:探讨局灶性癫癎发作间期和发作期脑电图变化特点及其在致癎灶定侧中的作用。方法:分析100例局灶性癫癎患者的发作间期、发作期脑电图及发作症状所提供的致癎灶侧别信息。结果:在这100例局灶性癫癎发作患者中,发作间期、发作期脑电图和发作症状可提供明确的致癎灶定侧的信息者分别为53例、76例和73例。结论:在致癎灶定侧诊断中,发作期与发作间期脑电图相比,可提供较高比例的侧别信息;综合分析发作间期、发作期脑电图和发作症状,可以使大部分局灶性癫癎发作的患者获得致癎灶的定侧信息,并为进一步埋置颅内电极,精确定位癫癎灶提供重要的参考。
Objective: To investigate the characteristics of epileptic seizures and the change of EEG during seizure and its role in the setting of seizures. Methods: 100 patients with focal epilepsy in the interictal period, attack EEG and seizures provided by the information provided by the side of the foci. RESULTS: Of the 100 patients with focal epilepsy, the interval between episodes, episodes of EEG and seizures provided clear information on the side of the popliteus, 53, 76, and 73 respectively. CONCLUSIONS: In the side-to-side diagnosis of pterygium, the seizure phase provides a higher proportion of side information than the seizure interval. Comprehensive analysis of the interictal, episodic EEG and seizures can Most patients with focal epileptic seizures get side information about the foci, and provide an important reference for further implantation of intracranial electrodes and precise positioning of epileptic foci.
