In a patient-specific case peak aneurysm wall stress was reduced by 92%. Such a reduction in aneurysm wall stress may lead to shrinkage of the aneurysm over time. Hence, post-operative stress patterns...
Fluid structure interaction of patient specific abdominal aortic aneurysms: a comparison with solid stress models
Fluid structure interaction patient specific abdominal aortic aneurysms solid stress models

Abdominal aortic aneurysm (AAA) is a dilatation of the aortic wall, which can rupture, if left untreated. Previous work has shown that, maximum diameter is not a reliable determinant of AAA rupture. H...
Fluid-structure interaction in abdominal aortic aneurysms: effects of asymmetry and wall thickness
Fluid-structure interaction abdominal aortic aneurysms

Both wall thickness and geometry asymmetry affect the stress exhibited by a virtual AAA. Our results suggest that an asymmetric AAA with regional variations in wall thickness would be exposed to highe...
