Evaluation of a 3D-Printed Stent-Graft for Aortic Aneurysms

Is this trial a fit for you?

A plain-English reading of the study's rules. Only the study team can confirm whether you qualify.

What this trial studies

This clinical trial compares the efficacy and safety of a physician-modified stent-graft created using 3D printing technology against standard custom-made devices for treating complex abdominal aortic aneurysms. It is a randomized, multicenter, open-label study involving approximately 100 patients, who will be assigned to either the innovative intervention or the standard procedure. The study includes a screening phase, intervention phase, and a 12-month safety follow-up to assess outcomes. Randomization will help minimize bias and ensure balanced characteristics among treatment groups.
