Summary

This registry is tracking how well two stent grafts, Castor and Cratos, work for treating aortic conditions like dissections and aneurysms. About 100 patients across European hospitals will be followed for up to 5 years. The goal is to see if these devices are safe and effective in real-world use.

What this could mean

Our plain-language read of the trial. This is informational only, not medical advice or a prediction.

Active substance: Castor and Cratos branched aortic stent grafts (medical devices)
What this could lead to: If successful, this registry could confirm that these stent grafts are safe and effective for treating serious aortic conditions in everyday practice.
What could go wrong: This is an observational registry, not a controlled trial, so results may be less definitive. Risks include device complications like leaks or migration, and the small size (100 patients) limits generalizability.
