Biofluid-Structural Interaction in Abdominal Aortic Aneurysm for Predicting Timeline to Rupture: The Effect of Hypertension and Aorta Wall Material Properties
Published in 2014
An abdominal aortic aneurysm (AAA) is a bulge formed in the large blood vessels that supply blood to the abdomen, pelvis, and legs. A fluid structure interaction model was developed in a 3D aortic aneurysm model, which was constructed from abdominal CT scan images. Combining medical imaging and computational fluid dynamics (CFD) in a time dependent study allowed the determination of wall stress, deformation, and fluid flow dynamic over a period of time. The model estimated the time to rupture based on the effects of hypertensive blood pressure and degradation of the diseased aortic wall mechanical properties.
