What this trial studies

This study investigates the use of coil embolization in the aneurysm sac during endovascular aortic aneurysm repair (EVAR) to prevent type II endoleaks (T2EL), which can lead to complications such as aneurysm growth or rupture. Patients with infrarenal abdominal aortic aneurysms (AAA) that meet specific criteria will be enrolled to assess the efficacy of this intervention. The study aims to determine if deploying metal coils can effectively reduce the risk of T2EL in high-risk patients. By identifying risk factors for T2EL, the study seeks to improve outcomes for patients undergoing EVAR.

Who should consider this trial

Good fit: Ideal candidates are adults aged 18 and older with infrarenal AAA of 50 mm or greater and specific high-risk criteria identified through CT imaging.

Not a fit: Patients with ruptured AAA, those requiring fenestrated or branched EVAR, or individuals unable to comply with follow-up protocols may not benefit from this study.

Why it matters

Potential benefit: If successful, this approach could significantly reduce the incidence of type II endoleaks and associated complications in patients undergoing EVAR.

How similar studies have performed: While the approach of coil embolization is being explored, the specific application in preventing T2EL during EVAR is relatively novel and has not been extensively tested in prior studies.
