Results: After a mean of 4.9 years of follow up, death from any cause in the two groups was not significantly different. Trends in survival did not immediately favor any of the prespecified subgroups defined by age or diameter of aneurysm of entry. These findings were obtained despite a low total surgical mortality of 2.7%. Eleven patients, 0.6% a year, in the conservatively treated group had rupture of aneurysms resulting in seven deaths.
Conclusion: Survival is not improved by elective repair of abdominal aneurysms smaller than 5.5 cm, even when operative mortality is low.
2. The UK Small Aneurysm Trial Participants
Study question: Which therapy is best, immediate repair or surveillance of small abdominal aneurysms?

Methods: In this study 1090 patients from age 60 to 76 with small aneurysms of 4–5.5 cm were randomly assigned to undergo elective surgery or to undergo surveillance by ultrasonography.
Results: The mean duration of survival was not signi¬ficantly different: 6.5 years in the surveillance group versus 6.7 years in the surgical group. The 30-day surgical mor¬tality was 5.5%.
Conclusions: Among patients with small abdominal aneurysms (< 5.5 cm), there appears to be no long-term difference in mean survival between early surgery and surveillance groups.
