EVAR's early mortality benefit warrants selective use in frail patients; confirms late aneurysm-related mortality excess versus open repair.
Does elective endovascular aneurysm repair (EVAR) reduce mortality compared to open repair in patients with abdominal aortic aneurysm?
EVAR offers an early survival advantage over open repair for abdominal aortic aneurysms, but this benefit is lost over time due to late aneurysm-related mortality.
