Description	The role of the Intra-luminal Thrombus (ILT) in Abdominal Aortic Aneurysm (AAA) rupture is controversial and it is still not clear if an ILT increases or decreases AAA rupture risk. Specifically, signs of bleeding in the ILT are thought to increase AAA rupture risk. In order to further investigate this hypothesis, intact AAAs (n=4) with clear signs of ILT rupture in Computer Tomography Angiography (CT-A) images were investigated. To this end two cases were investigated: an ILT failure extracted directly from the CT-A data and a hypothetical ILT fissure connecting the lumen with the underlying aneurysm wall. Wall stress distributions were predicted based on the detailed Finite Element (FE) models. The study showed that the ILT rupture, as extracted from the CT-A data, can increase the mechanical stress in the underlying wall by up to 30%. The largest impact on the wall stress was observed if the ILT failure reaches the aneurysm wall or if it involves large parts of the ILT. In contrast, a concentric f The role of the Intra-luminal Thrombus (ILT) in Abdominal Aortic Aneurysm (AAA) rupture is controversial and it is still not clear if an ILT increases or decreases AAA rupture risk.
