Endovascular aneurysm repair (EVAR) techniques have been widely used for the treatment of abdominal aortic aneurysm (AAA). EVAR is associated with lower postoperative morbidity and mortality compared with traditional and more invasive surgical procedure to treat AAA [1]. However, during the patient's follow-up, postoperative complications may occur and require secondary interventions, such as intimal hyperplasia and restenosis of the stent-grafts [2].
Stent-grafts implantation is a complex and strongly coupled biomechanical design between the stent and the AAA wall. During the implantation procedure, the injury to the arterial wall and stretching caused by the stent are thought to be the main causes of the proliferation of smooth muscle cells and inflammation from stent struts, which leads to the restenosis [3]. Stretching of the wall and the injury to the arterial wall are closely related to the stent structure, therefore, stent structure is an important factor...
