Italian registry of open and semi-conversion surgery after EVAR

Italian Multicenter Prospective Database for Open Conversions and SemiConversions After Endovascular Aneurysm Repair

Observational Azienda Ospedaliero-Universitaria di Parma · NCT04299984

This project collects information to see how open or semi-conversion surgery works for people who have late complications after endovascular abdominal aortic aneurysm repair (EVAR).

What this trial studies

This is a prospective, multicenter database collecting technical details and outcomes for patients who undergo late open conversion (partial or total graft explantation) or semi-conversion (open or laparoscopic repair with graft preservation) after EVAR. Participating vascular surgery centers enter procedural details, early postoperative results, and long-term follow-up data. The registry excludes purely endovascular reinterventions and extra-anatomical bypasses not involving direct aortic/graft surgery. The goal is to compare real-world early and long-term outcomes of the two surgical approaches to inform future practice.

Who should consider this trial

Good fit: Ideal candidates are people who previously had EVAR and now need open or laparoscopic surgery for EVAR complications, whether or not the endograft is removed.

Not a fit: People whose complications can be managed with repeat endovascular procedures or who require only extra-anatomical bypass without direct aortic/graft surgery will not be included and are unlikely to benefit from this registry.

Why it matters

Potential benefit: If successful, the database could clarify which surgical approach leads to better short- and long-term outcomes and help surgeons choose the right procedure for patients with failed EVAR.

How similar studies have performed: Several single-center series have reported outcomes after open conversion or semi-conversion, but prospective multicenter registries like this are relatively limited, so this effort builds on prior reports while expanding scale and generalizability.
