Abstract

Purpose: This study was designed to quantify and characterize the variations of hemodynamic parameters for those large cerebral aneurysms with outflow vessel in the plane of main vortex. Materials and Methods: A total of 19 consecutive patients with large cerebral aneurysms were constructed with the data of digital subtraction angiography. Those large cerebral aneurysms with outflow vessel in the plane of main vortex were included. Blood flow was hypothesized to be laminar and incompressible and blood Newtonian fluid. Computational fluid dynamics ICEM and Fluent software were used to simulate the computational hemodynamics of large cerebral aneurysms. Results: Hemodynamics parameters result of computational fluid dynamics showed that the velocity in the aneurysm neck, impact fields and the origin area of outflow vessels was obvious higher than that in the aneurysm sac and aneurysm dome. Wall shear stress was obvious higher in aneurysm neck, impact fields and the origin area of outflow vessels than that in the aneurysm sac and aneurysm dome. Conclusions: The location of outflow vessel played an impact on the level of blood flow within aneurysm sac for those large cerebral aneurysms with outflow vessel in the plane of main vortex.
