  "abstract": "Objectives: The aim of this study was to compare the effects of balloon-expandable and self-expanding stents on vessel wall mechanics and hemodynamics in a patient-specific saccular abdominal aortic aneurysm model.\n\nMethods: A patient-specific aneurysm model was constructed using computed tomography images, and balloon-expandable and self-expanding stent models were created. Aortic wall stress was evaluated by contact analysis. Fluid–structure interaction analyses were performed at 5 representative phases selected from the cardiac cycle. Mean intra-aneurysmal flow velocity, wall shear stress (WSS), pressure loss, and energy loss were compared.\n\nResults: The balloon-expandable stent produced greater localized aortic wall stress than the self-expanding stent, whereas wall stress was more uniformly distributed with the self-expanding stent. Both stents reduced the mean intra-aneurysmal flow velocity, WSS, pressure loss, and energy loss compared with the no-stent model. However, greater reductions in WSS, pressure loss, and energy loss were noted with the balloon-expandable stent than with the self-expanding stent.\n\nConclusions: Balloon-expandable and self-expanding stents exhibited different effects on vessel wall mechanics and hemodynamics. The findings indicate the importance of evaluating both hemodynamic and mechanical effects when assessing stent–vessel interactions.",
