Key result
Endovascular repair for ruptured abdominal aortic aneurysms was associated with a non-significant reduction in 30-day mortality compared to open surgery (adjusted OR 0.67; 95% CI 0.31-1.44).
Why the study?
Does endovascular repair reduce 30-day mortality compared to open surgery in patients with a ruptured abdominal aortic aneurysm?
Systematic Review (n=478)
Does endovascular repair reduce 30-day mortality compared to open surgery in patients with a ruptured abdominal aortic aneurysm?
Odds Ratio: 0.67 (95% CI 0.31–1.44)
Absolute Event Rate: 22% vs 38%
In patients with ruptured abdominal aortic aneurysms, endovascular repair showed a non-statistically significant trend toward lower 30-day mortality compared to open surgery after adjusting for hemodynamic presentation.
No takes yet. Share an insight, caveat, or question.
No significant mortality benefit shown with endovascular repair; leaves open need for randomized trials in ruptured abdominal aortic aneurysms.
Visser et al. (2007) conducted a systematic review in ruptured abdominal aortic aneurysm (AAA) (n=478). Endovascular repair vs. Open surgery was evaluated on 30-day mortality (adjusted OR 0.67, 95% CI 0.31, 1.44). Endovascular repair for ruptured abdominal aortic aneurysms was associated with a non-significant reduction in 30-day mortality compared to open surgery (adjusted OR 0.67; 95% CI 0.31-1.44).
