Key result
Open AAA repair yields similar long-term all-cause mortality to endovascular repair.
Why the study?
To evaluate long-term all-cause mortality, aneurysm-related mortality, and re-intervention after open versus endovascular repair for abdominal aortic aneurysm.
Does open repair compared to endovascular repair improve long-term mortality and re-intervention rates in patients with abdominal aortic aneurysm?
Meta-Analysis (n=88,818)
Does open repair compared to endovascular repair improve long-term mortality and re-intervention rates in patients with abdominal aortic aneurysm?
Odds Ratio: 1.16 (95% CI 0.89–1.51)
While open and endovascular repair for abdominal aortic aneurysm have similar long-term survival, endovascular repair carries a significantly higher risk of reintervention.

May support equivalent long-term survival after open or endovascular AAA repair; leaves open need for randomized confirmation.
Chen et al. (2019) conducted a meta-analysis in abdominal aortic aneurysm (n=88,818). Open repair vs. Endovascular repair was evaluated on all-cause mortality (OR 1.16, 95% CI 0.89-1.51). Open repair for abdominal aortic aneurysm had similar all-cause mortality to endovascular repair over 5 years (OR 1.16; 95% CI 0.89-1.51) and at least 10 years of follow-up.
