An endovascular stent graft is nothing but a small metal scaffold inside your aorta. The stent-graft generally supports the weak areas of your aorta. An endovascular stent graft is a non-invasive surgical procedure used to treat abdominal aortic aneurysm.
An aneurysm is generally considered as an increase in the original size of your blood vessels. The vessels are enlarged more than 50 % of their original size. The larger the aneurysm, the greater is the risk of rupture that can lead to complications.
