What this trial studies

This clinical trial evaluates the feasibility and safety of using the AneuFix device to fill the sac of asymptomatic abdominal aortic aneurysms (AAA) during endovascular aneurysm repair (EVAR) procedures. The AneuFix polymer is designed to block backflowing blood vessels, thereby preventing endoleaks by filling the voids and feeding arteries associated with the aneurysm. The study aims to determine how effectively this intervention can mitigate the risk of developing type II endoleaks in high-risk patients.

Who should consider this trial

Good fit: Ideal candidates are asymptomatic patients with infrarenal AAA who have a high risk of developing type II endoleaks and meet specific anatomical criteria.

Not a fit: Patients undergoing emergency procedures or those with ruptured or symptomatic AAA will not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce the incidence of endoleaks in patients undergoing EVAR for AAA.

How similar studies have performed: While the use of similar prophylactic techniques has been explored, the specific application of AneuFix in this context is novel and has not been extensively tested in prior studies.

Eligibility criteria
