An abdominal aortic aneurysm occurs when the wall of your aorta develops a bulge or aneurysm.
The aorta is your body’s largest artery, carrying blood to the abdomen, pelvis and legs. AAAs develop in the abdominal aorta, the portion of the aorta that passes through your belly. Aortic aneurysms disrupt the natural flow of blood to the abdomen, and EVAR prevents serious and even life-threatening consequences.
A similar procedure to EVAR, called thoracic endovascular aortic repair, is also available for people with thoracic aneurysms, which develop in the section of the aorta that travels through the chest.
