Saccular aneurysms on straight and curved vessels are subject to different hemodynamics: Implications of intravascular stenting
journal contribution
posted on 2019-10-29, 14:17 authored by H Meng, Z Wang, Minsuok KimMinsuok Kim, R Ecker, L HopkinsOur aim was to examine hemodynamic implications of intravascular stenting in the canine venous pouch (sidewall or straight-vessel) and rabbit elastase (curved-vessel) aneurysm models. Flow dynamics in stented (Wallstent) and nonstented versions were studied by using computational fluid dynamics simulations and in vitro flow visualization, with a focus on stent placement effects on aneurysmal flow stagnancy and flow impingement. Results show that sidewall and curved aneurysm models have fundamentally different hemodynamics (shear-driven versus inertia-driven) and thus stent placement outcomes.
