Follow-up and Study Endpoints
All patients were followed for at
least three years. The remodeling process was confirmed by the latest
CTA scan. The definition of the aortic remodeling process included the
stable, resolution and worsening of the hematoma. The primary outcome
was aortic-related mortality (confirmed by autopsy or CTA examination),
and the secondary outcomes were all-cause mortality and aortic
remodeling.
