BACKGROUND
Subarachnoid Hemorrhage (SAH) is caused principally by the rupture of intracranial aneurisms. Important risk factors have been described such as age, sex, hypertension (HT) and season of the year, among others. The objective is to investigate the demographic characteristics and possible risk factors in a population of Chilean patients.
METHODS
This retrospective study was based on the analysis of 244 clinical records of patients diagnosed with aneurismal SAH who were discharged from the Instituto de Neurocirugía ASENJO in Santiago, Chile.
RESULTS
The mean age of patients was 49.85 years and the male:female ratio was 1:2.7. The signs and symptoms were not different between sexes; cephalea (85.7%) was predominant, followed by loss of consciousness, vomiting/nausea and meningeal signs. Risk factors included sex, age and HT. Concordant with other reports, the incidence of SAH was greatest in spring.
CONCLUSIONS
The demographic characteristics and risk factors observed in patients with aneurismal SAH treated in ASENJO were comparable to those of other populations. We were not able to conclude that tobacco and alcohol consumption were risk factors for this population.
背景
蛛网膜下腔出血（SAH）主要由颅内动脉瘤破裂引起。已描述了一些重要的危险因素，如年龄、性别、高血压（HT）和一年中的季节等。目的是调查智利患者群体的人口统计学特征和可能的危险因素。
方法
这项回顾性研究基于对智利圣地亚哥阿森霍神经外科研究所出院的244例诊断为动脉瘤性SAH患者的临床记录分析。
结果
患者的平均年龄为49.85岁，男女比例为1:2.7。男女之间的体征和症状无差异；头痛（85.7%）最为常见，其次是意识丧失、呕吐/恶心和脑膜刺激征。危险因素包括性别、年龄和高血压。与其他报告一致，SAH的发病率在春季最高。
结论
在阿森霍接受治疗的动脉瘤性SAH患者中观察到的人口统计学特征和危险因素与其他人群相当。我们无法得出吸烟和饮酒是该人群危险因素的结论。
