  Figure 2.. Eventual repair rates for abdominal aortic aneurysms in the surveillance cohorts of the UKSAT 23, ADAM 24, CAESAR 25, and PIVOTAL 26 trials. The reasons for the eventual repairs included rupture, the onset of back pain or local tenderness, rapid growth on consecutive ultrasound scans or enlargement to a size exceeding the trial protocol, and patient preference.

  Figure 3.. Hazard ratios for endovascular aortic aneurysm repair versus open repair in a meta-analysis of pooled individual patient data from the EVAR-1, DREAM, OVER, and ACE trials 45. EVAR had a survival advantage at 6 months because of a lower 30-day mortality rate, followed by a gradually higher incidence of aneurysm-related deaths or re-interventions.
