A Comparative Study Based on Patient-SpecificFluid-Structure Interaction Modeling of CerebralAneurysms

[摘要] The Team for Advanced Flow Simulation and Modeling (T*AFSM) at Rice Universityhas been developing techniques to address the computational challenges involvedin fluid-structure interaction (FSI) modeling. The Stabilized Space-Time FSI(SSTFSI) core technologies, in conjunction with an array of special techniques, is usedin a comparative study of patient-specific cerebral aneurysms. Ten cases, from threedifferent locations, are studied, half of which were ruptured. The study compares thewall shear stress, oscillatory shear index, and the arterial-wall stress and stretch, withthe original motivation of finding significant differences between ruptured and unrupturedaneurysms. Simpler approaches to computer modeling of cerebral aneurysmsare also compared to FSI modeling.
