Rupture of an abdominal aortic aneurysm is an important cause of death, particularly for men over 60 years of age. The aim of elective surgery for abdominal aortic aneurysms is to prevent future death from rupture of the aneurysm. The present study examines the influence of elective surgery upon the rate of rupture, comparing 1980 when little elective surgery was done and 1989 when considerably more elective surgery was performed in a well defined population. The rate of rupture and death from such a cause was not affected by the increased number of elective operations. It is concluded that the number of operations generally performed is too small to significantly affect the mortality from rupture. In order to decrease this mortality patients with a high risk of rupture should be found and offered elective surgery.
腹主动脉瘤破裂是一个重要的死亡原因，尤其对于60岁以上的男性。腹主动脉瘤择期手术的目的是预防未来因动脉瘤破裂而死亡。本研究在一个明确界定的人群中，比较了1980年（当时择期手术很少）和1989年（当时进行了更多择期手术），考察择期手术对破裂率的影响。这种原因导致的破裂率和死亡率并未受到择期手术数量增加的影响。得出的结论是，一般进行的手术数量太少，不足以显著影响破裂导致的死亡率。为了降低这种死亡率，应该找出有高破裂风险的患者并为其提供择期手术。
