Clinical Trial Summary

The objective of this registry is to find and validate a correlation between morphological indicators such as volume sac evolution, graft migration or length between anatomical landmarks with aneurysm rupture risk or complications such as endoleaks requiring re-intervention… Secondary objectives are the validation of the reproducibility and accuracy of a dedicated fully automated software enabling Abdominal Aortic Aneurysm (AAA) segmentation to measure AAA diameter, volume evolution and growth over time, proximal and distal sealing zones analyze as well as device migration and integrity after EVAR on computed tomography angiography (CTA). This validation is in comparison with semi-automated analyse controlled by physician.
