Abstract:

influence of abdominal aortic aneurysms asymmetry on the hemodynamics within the aneurysmatic sac is analyzed and its influence on the rupture potential is discussed. a numerical study by using four idealized geometric models, with different asymmetry degrees, is carried out. blood is modelled as a newtonian, homogeneous, incompressible and laminar flow with properties as typically used in the literature. the results showed that the flow inside of the aneurysmatic sac is highly disturbed with intense vortex structures travelling from proximal to distal ends, strongly influencing on the wall shear stress distribution. it have also been established that, despite that the aneurysm are asymmetric, this factor has low weight on aneurysm rupture.
