目前通过采用各种治疗措施,颅内动脉瘤破裂患者的治疗效果获得稳步提高。但是,许多西方国家老年人比例不断增加,使老年动脉瘤患者手术治疗受到重视。作者分析了老年动脉瘤手术治疗的效果及其在临床社会经济方面的作用。研究分两部分,第一部分为98例老年动脉瘤病人的手术治疗效果;第二部分为80～90岁老年人SAH患者的发病率和自然病程。 Currently through the use of various treatment measures, the treatment of patients with intracranial aneurysm rupture has been steadily improved. However, the increasing proportion of the elderly in many Western countries places emphasis on the surgical treatment of elderly patients with aneurysms. The authors analyzed the effect of surgically treated elderly aneurysms and their role in clinical socio-economic aspects. The study is divided into two parts, the first part is the surgical treatment of 98 elderly patients with aneurysm; the second part is the incidence and natural history of SAH in 80 ~ 90 years old.
