Patient Specific Biomechanical Modeling of Abdominal Aortic Aneurysm to Improve Aortic Endovascular Repair

This project is aiming at the integration of a biomechanical computer program with a guidance code to simulate the endovascular repair (EVAR) procedure of abdominal aortic aneurysm (AAA). The computational time associated with finite element simulation generally renders its usage impractical for real-time application. Based on data collected during clinical interventions and a priori knowledge of AAA and endovascular device mechanical modeling, the investigators are proposing a deformable registration between preoperative CT-scans and per-operative fluoroscopy that will take into account prior simulations of participant specific EVAR procedures. To avoid the computational cost of a full finite element simulation, the investigators propose a simplified and real-time compliant repetitive mechanical behaviour based on participant specific parameters.

The results of this research will provide the Canadian industry with the first realistic deformable vascular geometry tool for live endovascular intervention guidance. The proposed biomechanical modeling can be translated to other vascular intervention procedure by adjusting the biomechanical parameters.
