It is important to detect predictive factors for in-hospital and delayed mortality of patients with subarachnoid hemorrhage (SAH) due to ruptured aneurysm. Forty-eight patients with initial bleeding of aneurysmal SAH were referred to our hospital from January 1982 to December 1985. In-hospital mortality was 16.7% (8 to 48), and 15% (6) of forty patients died later during the follow-up period. Using the Kaplan-Meier method we were able to conclude that, cumulatively, there was 70.8% probability that much patients would survive for 10 years. We analysed predictive factors of in-hospital and delayed mortality retrospectively. The most significant predictive factor for in-hospital mortality was SAH grading on admission, and for delayed mortality (29.2%) age on admission was the best predictive factor. In fact, two patients died with cardiac event during the follow-up period. This result suggests that, although the SAH grading on admission was the second most significant factor for delayed mortality, patients who survived in the acute phase had a survival probability similar to those in a normal control group.
检测因动脉瘤破裂导致蛛网膜下腔出血（SAH）患者的院内及延迟死亡率的预测因素很重要。1982年1月至1985年12月期间，48例动脉瘤性SAH初次出血患者被转诊至我院。院内死亡率为16.7%（8/48），40例患者中有15%（6例）在随访期间死亡。使用Kaplan-Meier方法，我们能够得出结论，累积来看，大部分患者存活10年的概率为70.8%。我们回顾性分析了院内及延迟死亡率的预测因素。院内死亡率最显著的预测因素是入院时的SAH分级，而对于延迟死亡率（29.2%），入院时的年龄是最佳预测因素。事实上，2例患者在随访期间死于心脏事件。该结果表明，尽管入院时的SAH分级是延迟死亡率的第二大显著因素，但急性期存活的患者的生存概率与正常对照组相似。
