Stent showdown: which device fixes aortic aneurysms faster?
NCT ID NCT07424885
First seen Jun 27, 2026 · Last updated Jun 27, 2026
Summary
This study compares two different stent systems used to repair a weakened area in the main artery (aortic aneurysm). About 126 adults will be randomly assigned to receive either the BeFlared or the VBX stent during a minimally invasive procedure. The goal is to see which device takes less time to place and which one keeps the repaired blood vessels stable over the next five years.
