It is estimated that approximately 2% of the entire population harbors an intracranial aneurysm; most of these patients, however, will never become symptomatic. The incidence of aneurysmal rupture as a cause of subarachnoid hemorrhage is 10 per 100,000 per year. The primary purpose of treatment for ruptured aneurysms is to prevent the often fatal rebleeding.
据估计，整个人口中约2%的人患有颅内动脉瘤；然而，这些患者中的大多数永远不会出现症状。作为蛛网膜下腔出血原因的动脉瘤破裂发生率为每年每10万人中有10例。破裂动脉瘤治疗的主要目的是预防常常致命的再出血。
