Why the study?
Does endovascular repair improve survival and prevent late rupture compared to open repair in the Medicare population with abdominal aortic aneurysm?
Does endovascular repair improve survival and prevent late rupture compared to open repair in the Medicare population with abdominal aortic aneurysm?
Endovascular repair of abdominal aortic aneurysm offers an early survival advantage over open repair that wanes over time, alongside a higher risk of late rupture.
May inform shared decisions on AAA repair type; leaves open optimal long-term surveillance in randomized data.
Endovascular repair, as compared with open repair, of abdominal aortic aneurysm was associated with a substantial early survival advantage that gradually decreased over time. The rate of late rupture was significantly higher after endovascular repair than after open repair. The outcomes of endovascular repair have been improving over time.
