The cerebral aneurysm is a dilatation of an arterial wall and its rupture is a devastating event associated with high rates of morbidity and mortality. It's of crucial importance to investigate the alteration of mechanical properties and blood flow in the artery associated with the formation of the aneurysm. Endovascular coiling, due to its minimally invasive nature, is increasingly being used to treat brain aneurysm. Like any surgical procedure, intraprocedural complications may occur . Doctors could use Fluid-Structure Interaction (FSI) simulation, a powerful tool for studying and quantifying hemodynamic outcomes in a brain aneurysm model and the effects of endovascular treatment.
