“…The Arbitrary Lagrangian-Eulerian (ALE) formulation is used, which is a widely used approach for vascular blood flow applications Formaggia et al 2001;Gerbeau et al 2005;Fernández et al 2008). Alternatively, one can apply the space-time methodology Torii et al 2008Torii et al , 2009, which leads to better time accuracy, yet somewhat higher computational expense per time step.…”

A computational vascular fluid-structure interaction framework for the simulation of patient-specific cerebral aneurysm configurations is presented. A new approach for the computation of the blood vessel tissue prestress is also described. Simulations of four patient-specific models are carried out, and quantities of hemodynamic interest such as wall shear stress and wall tension are studied to examine the relevance of fluid-structure interaction modeling when compared to the rigid arterial wall assumption. We demonstrate that flexible wall modeling plays an important role in accurate prediction of patient-specific hemodynamics. Discussion of the clinical relevance of our methods and results is provided.

Abstract. We propose a model for a medical device, called a stent, designed for the treatment of cerebral aneurysms. The stent consists of a grid, immersed in the blood flow and located at the inlet of the aneurysm. It aims at promoting a clot within the aneurysm. The blood flow is modelled by the incompressible Navier-Stokes equations and the stent by a dissipative surface term. We propose a stabilized finite element method for this model and we analyse its convergence in the case of the Stokes equations. We present numerical results for academical test cases, and on a realistic aneurysm obtained from medical imaging.Mathematics Subject Classification. 65M60, 74K25, 76D05, 76Z05.

“…In this context, numerical simulation using a combination of computational methods and medical imaging techniques for determining vascular geometry appears to be a relevant strategy. CFD starts to be a mature technique for arterial flows [23,24,25,26], but its application to heart haemodynamics faces additional challenges:…”
