Computer Aided Surgery: Application to Aortic Dissection

In cardiovascular disease, aortic dissection is relatively unknown and difficult to treat. Endovascular treatment seeks to obliterate the entrances to the false lumen with a stent. The currently available surgical tools for endovascular procedures are selected only from information based on medical imaging techniques. The images are carried out before the intervention and therefore do not consider the deformation of the vascular structure by the implementation of the prosthesis. While many biomechanical studies have been done on the endovascular treatment of aneurysms of the abdominal aorta, there are, however, very few such studies on aortic dissections. This paper aims to present a numerical tool, from the open-source software FOAM-Extend®, allowing for Multiphysics numerical simulations performing the fluid-structure coupling between the hemodynamics and the arterial deformation to assist in the planning process. And, in addition using Abaqus software we realize the placement of the surgical tools in a ‘biomecano-faithful’ model.
