Aortic stent grafting (EVAR)

Most of you will be familiar with insertion of stents after coronary angioplasty. A similar procedure for disease of the aorta is known as aortic stent grafting. It is different from simple stenting for obstruction of aorta which can occur as a birth defect. The stent graft is a metallic stent covered with fabric so that it can be used to prevent leakage of blood from the stented region. Stent grafts are used for treatment of localized enlargements of the aorta known as aortic aneurysms. Aorta is the largest blood vessel carrying oxygenated blood to the whole body.
