【摘要】 目的探讨蛛网膜下腔出血(sah)对保险公司的直接请求权，从而缓解了患者在请求赔偿方面的特点及
法医学鉴定要点。 方法 通过对华西医科大学法医鉴定中心1983—2001年尸检检出的127例各种原因所致的sah案
例进行回顾性分析。 结果各类sah案例，男性明显多于女性，男女性别比为3：1，高峰年龄为21～40岁。按sah 常见
特征可分为外伤性、脑血管畸形、动脉瘤、脑血管粥样硬化、中毒、伴发于心脏疾患、其他等八类。其中，外伤性与脑血管畸
形最为多见。外伤性sah与脑血管畸形出血可见于任何年龄，多见于l1～50岁，脑血管粥样硬化出血仅见于50岁以上
者，动脉瘤破裂出血者并不多见，见于l1～50岁。以sah为死亡原因者，32例，占25％ ，多见于脑血管畸形与动脉瘤破裂，
出血部位多见于脑底及小脑天幕以下。大多数sah，出血部位多见于大脑表面，较为局限，出血量较少，非死亡的主要原
因。 结论多数sah并非导致死亡的主要原因，sah死亡者，其死亡性质多属自然死亡。
