Is this trial a fit for you?

Likely a good fit

Adults (over 18) who received a Castor or Cratos single-branch endograft incorporating the left subclavian artery in a thoracic aortic pathology.

Probably not a fit

Patients not receiving a Castor or Cratos graft, or those with infections, pregnancy, or other exclusion criteria, may not benefit from the registry data.

What this trial studies

The CEDAR registry is an observational, multi-center study that combines retrospective and prospective data. It aims to track safety and performance of Castor and Cratos branched stent grafts used in endovascular treatment of thoracic aortic pathologies in the descending aorta. The study plans to enroll about 100 patients across European hospitals and follows them over short, medium, and long-term periods. Data collection includes real-world outcomes, device performance, and any complications related to the implants. It is sponsored by Shanghai MicroPort Endovascular MedTech Group, with participating sites in Hamburg, Münster, and Sion.

Why it matters

Potential benefit: If successful, the registry could clarify real-world durability and safety of Castor and Cratos grafts in diverse patient populations.

How similar studies have gone: Previous post-market registries and observational studies in endovascular aortic repair have provided actionable safety and performance data for similar devices.
