目的:探讨老年人动脉瘤性蛛网膜下腔出血继发癫痫的相关因素。方法:选取武汉市中医医院2015年1月至2019年1月收治的老年动脉瘤性蛛网膜下腔出血患者213例，根据是否继发癫痫分为癫痫组46例与无癫痫组167例。采用单因素分析影响老年人动脉瘤性蛛网膜下腔出血继发癫痫的相关因素，采用多因素logistic回归分析影响老年人动脉瘤性蛛网膜下腔出血继发癫痫危险因素。结果:单因素分析结果显示，两组性别、年龄、合并糖尿病和吸烟史差异均无统计学意义(均n P>0.05)；癫痫组与无癫痫组合并高血压(15例比22例)、责任动脉瘤位于大脑中动脉(22例比24例)、动脉瘤数量多发(23例比41例)、颅内血肿(15例比26例)、脑积水(15例比21例)和神经功能后遗症(14例比20例)差异均有统计学意义(χn 2＝9.491、23.840、11.113、6.737、10.306、9.161，均n P0.05). There were statistically significant differences between the epilepsy group and non epilepsy group in hypertension(15 cases vs.22 cases), location of responsible aneurysms in middle cerebral artery(22 cases vs.24 cases), number of aneurysms(23 cases vs.41 cases), intracranial hematoma(15 cases vs.26 cases), hydrocephalus(15 cases vs.21 cases) and neurological sequelae(14 cases vs.20 cases)(χn 2=9.491, 23.840, 11.113, 6.737, 10.306, 9.161, all n P<0.05). The results of multivariate analysis showed that hypertension, middle cerebral artery, multiple aneurysms, intracranial hematoma, hydrocephalus and neurologic sequelae were risk factors for epilepsy secondary to aneurysmal subarachnoid hemorrhage in the elderly[n OR(95%n CI)2.361(1.476-3.421), 3.012(1.935-1.845), 1.494(1.027-1.845), 2.785(1.684-3.982), 1.920(1.283-2.984), 1.637(1.171-2.316)].n Conclusion:There are many factors influencing secondary epilepsy in elderly patients with aneurysmal subarachnoid hemorrhage.In order to reduce the incidence of secondary epilepsy, preventive measures should be taken against the above risk factors.
