A study of 788 cases of spontaneous subarachnoidal hemorrhages, which were observed in some neurological clinics during the past 5 years, permitted an analysis of the statistical data concerning the distribution and outcomes of this form of strokes depending upon the age of the patient and etiology. Among the observed population, individuals of a young and middle age prevailed (78% of the patients were younger than 60 years). The role of separate etiological factors is different in different age groups in individuals under 40, subarachnoidal hemorrhages are mainly produced by a rupture of cerebral vascular aneurysms; in the age group of 40--59 years by arterial hypertension, while in the elderly by atherosclerosis in combination with arterial hypertension. The outcomes of subarachnoidal hemorrhages in general are more favourable in the older age groups. However, in hemorrhages of an aneurysmal etiology the lethality amounts to 21%, and is especially high in repeated strokes. In the group of patients with hemorrhages of an aneurysmal etiology the highest lethality was recorded in a localization of the aneurysm in the anterior communicating artery and anterior cerebral artery.
对过去5年在一些神经科诊所观察到的788例自发性蛛网膜下腔出血病例进行的一项研究，得以对有关这种中风形式的分布和预后的统计数据进行分析，这些数据取决于患者的年龄和病因。在观察到的人群中，中青年占多数（78%的患者年龄小于60岁）。不同年龄组中不同病因因素的作用各不相同：在40岁以下的个体中，蛛网膜下腔出血主要由脑血管动脉瘤破裂引起；在40 - 59岁年龄组中由动脉高血压引起，而在老年人中则由动脉粥样硬化合并动脉高血压引起。一般来说，蛛网膜下腔出血的预后在老年组中更有利。然而，动脉瘤性病因的出血致死率为21%，在复发性中风中尤其高。在动脉瘤性病因出血的患者组中，动脉瘤位于前交通动脉和大脑前动脉时致死率最高。
