Computational Study of Stented Aortic Arch Aneurysms

This computational study is motivated by the fact that there is still incomplete knowledge to date about hemodynamics of stented aortic arch aneurysms harboring a bleb. The hemodynamics in the stented and nonstented models of aortic aneurysms were analyzed and compared using the method of computational fluid dynamics. Flow activities inside the stented aneurysm model were significantly diminished, specifically the pressure and wall shear stress in the bleb were decreased, thus promoting intra-aneurysmal thrombus development and attenuating aneurysm rupture risk. The present study indicated that it is effective to treat aortic arch aneurysms with endovascular stents
