Impact of poroelasticity of intraluminal thrombus on wall stress of abdominal aortic aneurysms
Background The predictions of stress fields in Abdominal Aortic Aneurysm (AAA) depend on
constitutive descriptions of the aneurysm wall and the Intra-luminal Thrombus (ILT). ILT is a
porous diluted structure (biphasic solid–fluid material) and its impact on AAA biomechanics
is controversially discussed in the literature. Specifically, pressure measurements showed
that the ILT cannot protect the wall from the arterial pressure, while other (numerical and
experimental) studies showed that at the same time it reduces the stress in the wall. Method …
