What is an endovascular stent graft?

An endovascular stent graft is a tube composed of fabric supported by a metal mesh called a stent. It can be used for a variety of conditions involving the blood vessels, but most commonly is used to reinforce a weak spot in an artery called an aneurysm. Over time, blood pressure and other factors can cause this weak area to bulge like a balloon and it can eventually enlarge and rupture. The stent graft is designed to seal tightly with your artery above and below the aneurysm. The graft is stronger than the weakened artery and it allows your blood to pass through it without pushing on the bulge. Physicians typically use endovascular stent grafting to treat abdominal aortic aneurysms (AAAs), but they also use it to treat thoracic aortic aneurysms (TAAs) and less commonly, aneurysms in other locations.

Aneurysms often affect the aorta, your body?s largest artery. Your aorta carries blood away from the heart and it runs from your heart through your chest and abdomen. The normal diameter of the aorta in the abdomen is about 2 centimeters, which is a little less than 1 inch. An aneurysm is considered to have formed if the aorta grows to more than 1
