EVAR's early survival edge does not persist; leaves open optimal repair choice and surveillance needs in intact AAA.
Does endovascular aneurysm repair (EVAR) improve long-term survival compared with open repair in patients aged 60 years or older with intact abdominal aortic aneurysms?
EVAR offers an early survival benefit over open repair for abdominal aortic aneurysms, but this is offset by inferior late survival driven by secondary aneurysm sac rupture, highlighting the need for lifelong surveillance.
