Abstract Endovascular repair has emerged as an alternative, less-invasive surgical technique for the treatment of patients diagnosed with abdominal aortic aneurysms (AAAs). The anatomical pathway of blood flow in the abdominal aorta is restored by the implantation of an endovascular graft (EVG), depressurizing the aneurysm and initiating a remodeling process of the diseased aortic tissue. The short-term results of endovascular grafting are promising, but its long-term success has been compromised by the occurrence of graft migration or detachment, which induce endoleaks or incomplete occlusion of the aneurysm from the bl
