Computational Models of Cerebral Aneurysms Using Intravascular Hemodynamic Measurements

The hemodynamic environment of intracranial aneurysms is considered an important promoter of aneurysmal formation, growth and rupture [1]. Flow-diverting stent technology [2] has been developed to reduce blood flow (and hence hemodynamic stress) inside the aneurysm, potentially lowering the rupture risk. Computational fluid dynamics (CFD) modeling of aneurysms and the surrounding cerebral vasculature allows investigators to calculate important hemodynamic characteristics such as wall shear stress (WSS), which have been implicated in aneurysm growth and rupture.
