Long-term follow-up of Intergard vascular grafts and patches

Post-Market Clinical Follow-up Registry to Evaluate the Safety and Performance of the Intervascular Vascular Grafts and Patches in Patients Undergoing Bypass, Replacement, or Repair of Aortic, Peripheral, or Carotid Arteries

Intervascular · NCT07322913

This registry will see how Intergard grafts and patches perform and stay safe over time in adults who had bypass, repair, or replacement of the aorta, carotid, or peripheral arteries.

What this trial studies

This observational registry collects long-term safety and performance data on four Intervascular devices (Intergard Standard, Hemashield, Intergard Silver, Intergard Synergy) used for aortic, peripheral, or carotid bypass, repair, or replacement. Participating adults who previously received one of these grafts or patches will have existing clinical records reviewed, with a minimum of three years of follow-up data required. The registry specifically records device longevity and gathers information on the usefulness of antimicrobial coatings. Data are collected at participating centers in the US, France, and Spain without assigning new treatments.

Who should consider this trial

Good fit: Adults (18+) who previously underwent bypass, replacement, or repair of the aorta, carotid, or peripheral arteries using an Intergard device and who can provide at least three years of follow-up records and informed consent are ideal candidates.

Not a fit: Patients who did not receive an Intergard device, those lacking the required medical records or consent, and patients who had an active infection at the device site at the time of implantation (for some devices) are unlikely to benefit from joining this registry.

Why it matters

Potential benefit: If successful, the registry could clarify expected device lifetime and whether antimicrobial coatings reduce complications, helping doctors choose the best graft for future patients.

How similar studies have performed: Intervascular grafts and patches are widely used and prior observational work supports their general safety, but long-term, comparative data on device lifetime and the added value of antimicrobial coatings remain limited.
