Overview
Brief Summary
Endoprosthesis treatment of aortic pathologies has become the reference in the vast majority of situations. The success of this treatment is conditioned by the choice of the endoprosthesis which must be as adapted as possible to the anatomy. This choice is currently based on manual geometric measurements performed on the preoperative scanner using conventional image processing software.
The morphological result of the implantation of the endoprosthesis in the aorta is obtained by a CT scan carried out postoperatively. This scanner makes it possible to define the positioning of the endoprosthesis, the apposition surfaces between the aorta and the endoprosthesis and to predict the long-term result.

Outcomes
Primary Outcomes
The accuracy of numerical simulation to predict the deployment at the level of the proximal neck of different types of standard stents used for the treatment of an aortoiliac aneurysm.
Time Frame: through study completion, an average of 1 year
Wwill be evaluated by measuring the diameter and the position of the center of the first 3 simulated proximal stents will be compared to those of the real stents, analyzed on the post-operative scanner
