Intracranial and abdominal aortic aneurysms: similarities, differences, and need for a new class of computational models. (2008, methodology): “Raghavan & Vorp (128) performed 1D tests on 69 human AAA specimens oriented along either the circumferential or the axial Humphrey and Taylor Page 8”
Prediction of rupture risk in abdominal aortic aneurysm during observation: wall stress versus diameter. (2003, background): “Some of these issues are controversial, such as inclusion of thrombus, with studies suggesting it may increase stress or rupture risk, decrease wall stress, or have no effect.(29-32,37) Shear stress could be added to the model, but physiologic shear stress on the inner wall is a tiny percentage of t”
