3D Hemodynamic Numerical Simulation of an Intracranial Aneurysm Model before and after Embolism Treatment

Intracranial aneurysms are pathological dilatations of the arterial wall. Hemodynamic factors like the wall shear stress play an important role in the formation, growth and rupture of intracranial aneurysms; however, their natural growing history is not well understood. In this paper, we created 3-D models of intracranial aneurysms based on patient-specific 3DRA images and performed hemodynamic numerical simulation of the models before and after embolism treatment. We found the difference in these hemodymodynamic parameters before and after embolism. The study can provide useful information for the rupture mechanism analysis and clinical diagnosis of intracranial aneurysms.
