Compare the computational fluid dynamics (CFD) results of ruptured abdominal aortic aneurysm (RAAA) and asymptomatic intact abdominal aortic aneurysm (IAAA) for groups. Compared with the diameter-matched asymptomatic IAAA group, the RAAA showed significantly larger peak wall stress (PWS), maximum deformation (MD), relative residence time (RRT), endothelial cell activation potential (ECAP), and peak wall rupture index (PWRI), smaller wall shear stress (WSS). OSI = Oscillatory shear index.
