简介：目的探讨动脉瘤性蛛网膜下腔出血（aSAH）患者的临床特点及其与预后的相关因素。方法回顾性分析大连医科大学附属第二医院神经外科2012年1月至2015年10月收治的107例SAH患者,根据GOS评分将病例分为预后良好组及不良组,采用单因素分析及对多因素Logistic回归分析,探讨上述各因素对预后的影响。结果全部107例患者经单因素分析显示,诱因、动脉瘤大小、Hunt-Hess评分、脑血管痉挛与患者预后明显相关（均P〈0.05）。多因素Logistic回归分析显示,诱因（P=0.026）、动脉瘤大小（P=0.002）、Hunt-Hess评分（P=0.016）及脑血管痉挛（P=0.003）为影响aSAH患者预后的独立危险因素。结论aSAH患者的发病诱因、动脉瘤大小、Hunt-Hess分级和脑血管痉挛是影响患者预后的危险因素。
