枕叶癫痫的临床特征分析及手术治疗

目的：癖结枕叶癫痫的临床特征及手术效果，方法：对病人进行电生理学，CT，MRI及ECT检查，手术中行皮层脑电监测，结果，枕叶癫痫病人31例，年龄3至34岁，临床主要表现有视觉异常发作，头偏转，颞叶样或（及）额顶样发作，头皮脑电显示31例病人中30例枕叶或枕叶及周围脑叶出现棘波，CT检查27例中24例异常，MRI检查9例中8例异常，ECT检查13例中11例术区皮层血流减少，所有病人均在皮层脑电监测下切除病灶，术后随访到22例（时间1至4年），11列无痫发作，其余明显好转，结论，枕叶癫痫的临床特点包括，视觉异常发作，癫痫发作形式多样，枕叶区域异常脑电及影像学改变，手术切除病灶能获得好效果。

Clinical features of occipital lobe epilepsy and its surgical treatment

Objective To characterize the clinical features of occipital lobe epilepsy and to evaluate the outcome of its surgical treatment. Methods Neurological and scalp EEG studies were performed on patients with epilepsy, as well as CT, MRI, ECT and intracranial EEG. Results Thirty one patients with occipital lobe seizure were reported. The ages of patients ranged from 3 to 34 years old. The clinical manifestations included visual seizure, head deviation, temporal lobe or fronto parietal lobe seizure. Scalp EEG recordings showed occipital epileptiform discharge in 30 of 31 patients. CT scans showed abnormality in 24 of 27 patients, MRI showed abnormality in 8 of 9 patients. ECT showed a decreasing of cerebral blood flow in cortex of 11 among 13 patients. All patients were operated on by resections of the epileptogenic foci. With a follow up period ranged from 1 to 4 years, which was available for 22 patients, it showed that 11 patients became seizure free and others had a great reduction in frequency of seizure. Conclusions Our results indicates that occipital lobe epilepsy is characterized by ictal visual abnormality and occipital epileptiform discharges on scalp EEG. The outcome of surgical treatment of occipital lobe epilepsy is excellent.
