对挪威五个外科科室的434例腹主动脉瘤患者的生存模式和生存概率进行了研究。其中，择期手术200例(中位年龄63岁)，动脉瘤破裂173例(中位年龄69岁)，即将破裂61例(中位年龄67岁)(即急诊手术但未发现破裂)。住院死亡率分别为3.5%、59%和24.6%。将这些群体的总体生存概率与人口统计相似的人群(标准人口)的总体生存概率进行了比较。接受择期手术的患者的生存概率略低于标准人群，但显著低于标准人群，而接受紧急手术并在术后第一个月存活的患者与标准人群相比，死亡风险没有增加。对于择期手术组，年龄对生存有显著影响，而手术时间没有显著影响。在动脉瘤破裂组中，患者的年龄和手术时间对生存率有显著影响，而对于即将破裂的患者则没有发现这种影响。患者在手术中存活的概率总体较好，5年生存率较高。破裂动脉瘤患者的死亡率从I期(1976年前进行的手术)到II期(1976年或以后进行的手术)显著降低。高龄患者的生存概率相对较好，即使是紧急手术的患者也是如此。
Cases of 434 patients who underwent surgery for abdominal aortic aneurysms in five surgical departments in Norway have been studied with respect to survival patterns and survival probabilities. Of these, 200 patients (median age 63 years) had elective surgery, 173 patients (median age 69 years) had ruptured aneurysms, and 61 patients (median age 67 years) had impending rupture (i.e., emergency operations were performed, but no rupture was found). The hospital mortality rates in the groups were 3.5%, 59%, and 24.6%, respectively. The general probabilities of survival of these groups have been compared with those of a demographically similar population (standard population). Patients who had elective surgery had a slightly, but significantly, lower survival probabilities than did the standard population, whereas the patients who underwent emergency surgery and who survived the first postoperative month showed no increased risk of dying as compared with the standard population. For the elective surgery group, age had a significant effect on survival, whereas the period of operation did not. In the group with ruptured aneurysms both the age of the patient and the period of operation had significant effects on survival, whereas no such effects were found for patients with impending rupture. The survival probabilities for patients surviving the operation were generally good, with a high 5-year survival rate. The mortality rate for patients with ruptured aneurysms decreased significantly from period I (surgery performed before 1976) to period II (surgery performed in 1976 or later). The survival probabilities for patients of advanced age were relatively good, even for patients who had emergency surgery.
