REGISTRY for the Use of a Software for Automatic Detection of the Evolution of Aneurysmal Volume and Graft Migration After EVAR (EndoVascular Aneurysm Repair)

Withdrawn
Conditions
Aneurysm Aortic
Interventions
Procedure: CT-Scan
Registration Number
NCT05964348
Lead Sponsor
University Hospital, Bordeaux
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.

Primary Outcome Measures
NameTimeMethod
Measurement of length between anatomical points evolutionMonth 12

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 EVARMonth 12

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 evolutionMonth 12

Measurement of the aneurysm sac volume in cc on the CT scans available

Measurement of graft migrationMonth 12

Measurement of the graft migration if existing on the CT scans available

Measurement of morphological neck characteristicsMonth 12

Measurement of the morphological neck characteristics in mm on the CT scans available

Secondary Outcome Measures
NameTimeMethod
Repeatability between measures (intra observer variability)Month 12

Descriptive analysis of the different measurements by overlaps metric analysis

Average time for segmentation (sec)Month 12

The time for segmentation by junior/senior surgeon and software is recorded

Repeatability between one senior and one junior surgeon (inter observer variability) for the Semi-automatic segmentationMonth 12

Descriptive analysis of the semi-automatic segmentation for the junior and senior surgeon by overlaps metric analysis

Average time for segmentation in comparison with semi-automated segmentationMonth 12

Description of the average time between the different techniques.

Total Volume measurement of AAAMonth 12

Description of the volume measurement of the AAA with the following items:

* Volume circulating

* Intraluminal thrombus volume

* Calcification volume
