Between 1988 and 2000, conventional repair of intact abdominal aortic aneurysms in the US became safer with lower mortality and shorter hospital stays, providing benchmark data for comparison with endovascular repair.
Wainess et al. (2004) conducted an observational in Abdominal aortic aneurysm (n=104,023). Conventional AAA repair vs. Trends over time (1988 vs 2000) was evaluated on Operative mortality for intact AAA repair (p=<.001). Operative mortality for intact conventional abdominal aortic aneurysm repair decreased significantly from 6.5% in 1988 to 4.3% in 2000 (p < .001), alongside shorter hospital stays.
