CT Scan Study of Aortic Arch Structure in People With and Without Aneurysms

What this Trial Is About

Researchers are investigating the anatomical features of the aortic arch, focusing on a common variant called the common origin of the innominate and left carotid artery CILCA, which has been linked to thoracic aortic disease TAD. The study aims to compare these anatomical characteristics in people with and without aneurysms, collecting data from five major European cardiovascular centers. This observational study involves analyzing CT scans of the aortic arch from two groups individuals without aneurysms requiring treatment and those with aneurysms that do require treatment. No interventions or treatments are administered instead, the study focuses on imaging data to understand differences in aortic arch anatomy. Participants undergo aortic arch CT scans at participating centers, and researchers measure changes and differences in aortic arch anomalies from baseline within 30 days. The study tracks these anatomical features to better understand their relationship to aortic aneurysms and potential risks. The total study period extends until December 2026.
