Thrombosis modeling in stented cerebral aneurysms with Lattice Boltzmann method

Research output: Chapter in Book/Report/Conference proceedingConference contributionAcademicpeer-review

Abstract

This contribution presents the results of numerical simulations of thrombosis in a patient specific cerebral aneurysm, deployed with stents of different porosity. The thrombosis models are based on low wall shear stress constraint and high residence time of fluid. Simulations have been performed with a massively parallel Lattice Boltzmann solver on 8192 cores of Intel Sandy Bridge processors. Our studies show that the treatment of a cerebral aneurysm with a flow diverter stent induces thrombosis in the aneurysm bulge, which is even more intense with a less porous stent, due to enhanced flow diversion.
