美国大约有5％的成年人颅内隐藏着一个或一个以上的囊性动脉瘤。按11/10万的蛛网膜下腔出血发病率计,估计美国和加拿大每年约有26,000人罹患本病。在过去十年中动脉瘤破裂所致的蛛网膜下腔出血的总发病率,并不象其它类型的脑血管病和心血管病那样呈下降趋势,而仍在继续威胁着具有工作能力和看来身体健康的青壮年,但也可发生于老年和偶见于少年。不管在诊断和治疗方面所取得的研究成果如何,本病的总发病率和病死率仍然较高,且约有60％的病人为妇女。据 Adams 的新近报告,接受动脉瘤研究机构合作治疗的249例蛛网膜下腔出血病人在3天内死亡者达36％,约有18％的病人在出血90天后仍有严重的神经系统后遗症。如要降低本病的病死率和病残率,就必须早期诊断和提高疗效,并对尚未破 About 5% of adults in the United States have one or more cystic aneurysms hidden in the skull. According to the incidence of subarachnoid hemorrhage of 11 / 100,000, it is estimated that about 26,000 people in the United States and Canada suffer from this disease every year. The overall incidence of subarachnoid hemorrhage due to ruptured aneurysms over the past decade does not show the same downward trend as other types of cerebrovascular disease and cardiovascular disease but continues to threaten the ability to work and look To healthy young adults, but can also occur in old age and occasionally in juvenile. Regardless of the research findings in diagnosis and treatment, the overall morbidity and mortality of this disease are still high, and about 60% of the patients are women. According to a recent report by Adams, 249 patients with subarachnoid hemorrhage co-treated with aneurysm research have a 36% mortality within 3 days and about 18% have severe neurological sequelae 90 days after bleeding. If you want to reduce the mortality and morbidity of this disease, we must early diagnosis and improve the efficacy, and not yet broken
