Brief 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.

Design outcomes
Primary
| Measure | Time frame | Description |
|---|---|---|
| Measurement of length between anatomical points evolution | 6 months before intervention | Measurement of the length between anatomical points evolution of the aneurysm in mm on the CT scans available. |
| Collection of the different events and complications of the aneurysm post EVAR | Month 1 | Collection of the different events and complication occurred after the EVAR (post-operative (up to one month), 3, 6 and 12 months). The collection will be use to correlate with the measurement of the morphological indicators collected at the different time frame of the study |
| Measurement of aneurysm sac volume evolution | Month 1 | Measurement of the aneurysm sac volume in cc on the CT scans available |
| Measurement of morphological neck characteristics | Month 6 before intervention | Measurement of the morphological neck characteristics in mm on the CT scans available |
| Measurement of graft migration | 6 months before intervention | Measurement of the graft migration if existing on the CT scans available |
Secondary
| Measure | Time frame | Description |
|---|---|---|
| Repeatability between one senior and one junior surgeon (inter observer variability) for the Semi-automatic segmentation | Month | Descriptive analysis of the semi-automatic segmentation for the junior and senior surgeon by overlaps metric analysis |
| Repeatability between measures (intra observer variability) | 6 months before intervention | Descriptive analysis of the different measurements by overlaps metric analysis |
| Average time for segmentation (sec) | 6 months before intervention | The time for segmentation by junior/senior surgeon and software is recorded |
| Average time for segmentation in comparison with semi-automated segmentation | 6 months before intervention | Description of the average time between the different techniques. |
| Total Volume measurement of AAA | 6 months before intervention | Description of the volume measurement of the AAA with the following items: * Volume circulating * Intraluminal thrombus volume * Calcification volume |
