Abdominal aortic aneurysm (AAA) is a pathological, localized and permanent dilatation of abdominal aorta that leads to vascular wall weakening due to the loss of mechanical properties caused by collagen and elastin degradation. If vessel’s diameter dilatation is larger than 3 centimeters the patient is subjected to a surveillance protocol and if needed he has to be treated to prevent aneurysm rupture and patient’s death. AAA can be treated by two techniques: open surgical repair (OSR), performed by an incision in the patient abdominal area, and endovascular repair (EVAR), performed by two incision in the groin area. The aim of the techniques is to exclude the aneurysm from the blood flow.
