Outcomes of Open Repair, Fenestrated Stent Grafting, and Chimney Grafting in Juxtarenal Abdominal Aortic Aneurysm: Is It Time for a Randomized Trial?

Background: The well-established, gold standard treatment for juxtarenal abdominal aortic aneurysms (JAAAs) is open repair (OR). However, endovascular treatment with fenestrated or chimney grafts has been increasingly performed in the past decade. This study compared the outcomes of OR with 2 endovascular methods in JAAA.
