Validation of Numerical Simulation to Predict Proximal Deployment of Standard Stents

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.
