Why the study?
Does endovascular repair improve long-term overall survival compared to open repair in patients with abdominal aortic aneurysm?
Does endovascular repair improve long-term overall survival compared to open repair in patients with abdominal aortic aneurysm?
Long-term overall survival is similar between endovascular and open repair for abdominal aortic aneurysms, contrasting with previous European trials.
Supports individualized AAA repair choice without survival penalty; challenges prior European trial findings.
Long-term overall survival was similar among patients who underwent endovascular repair and those who underwent open repair. A difference between groups was noted in the number of patients who underwent secondary therapeutic procedures. Our results were not consistent with the findings of worse performance of endovascular repair with respect to long-term survival that was seen in the two European trials.
