Two-dimensional numerical analysis of local hemodynamics on flow-reduction mechanism by stent implantation in cerebral aneurysms is presented to understand these interesting hydrodynamic phenomena and improve this promising minimally invasive treatment. Recently in the cerebral aneurysm treatment, this new endovascular occlusion technique using a porous tubular shaped stent or coils sometimes replaces invasive open surgeries. It is thought that the flow reduction by the stent implantation prevents the aneurysm rupture, however its mechanism is not well understood. We reveal the fundamental flow reduction mechanism by the stent implantation in dependence of the aneurysm size using the lattice Boltzmann approach.
