Abstract. Abdominal aortic aneurysm (AAA) is an irreversible dilation of abdominal aorta, which may rupture if not surgically treated. To date, most aorta stent-graft used in clinical practice are batch manufactured devices with a uniform diameter. Custom abdominal aortic stent-grafts are able to overcome standard stents limitations. In this study, a customized aortic stent-graft (NiTi -Dacron) for the treatment of AAA has been proposed. Fluid dynamics analyses were performed to deepen the hemodynamic of aneurysm vessel and the proposed patient-specific graft. By means this study, the authors have shown the real benefits of the device for the patient and the possibility to apply this new stent-graft in the near future.
