The influence of hemodynamic factor is investigated using computational fluid dynamic (CFD) method on the virtual AAA model and the results show the forming of vortices is seen at the aneurysm bulge then destroyed rapidly by flow recirculation.

Inclusion of calcifications in finite element analysis of AAAs resulted in a marked alteration of the stress distributions and should be included in rupture risk assessment, and the results suggest that the location and shape of the calcified regions--not only the relative amount--are considerations that influence the effect on AAA wall stress.

The presence of ILT alters the wall stress distribution and reduces the peak wall stress in AAA, and should be included in all patient-specific models of AAA for evaluation of AAA wall stresses.

The results provide further support to previous findings that the presence of ILT may significantly impair oxygen transfer from blood to the aortic wall, and demonstrate that adventitial oxygen concentration has a profound effect on oxygen concentration in the wall.

The results suggest that ILT is an inhom*ogeneous and possibly isotropic material and the constitutive model derived here for ILT can be easily incorporated into finite element models for simulation of wall stress distribution in AAA.

Flow dynamics in model aneurysms under physiologically realistic pulsatile flow condition via computational modeling techniques found that flow in larger models become increasingly unstable compared to smaller models, contributing significantly to wall shear stress magnitude and subsequently contributing to higher rupture risks.
