Hello, I am Dr Manish Mehta and this is a Society for Vascular Surgery briefing about Risks and Benefits of Endovascular Abdominal Aortic Aneurysm Repair. An aneurysm is a progressive weakening and ballooning of blood vessels in the body. The abdominal aorta is one of the largest arteries in the body that supplies blood to all of the abdominal organs, and just below the naval it divides into iliac arteries that supply the pelvis and the legs. An abdominal aortic aneurysm is weakening and dilatation of the abdominal aorta that if undiagnosed and untreated, can lead to aneurysm rupture resulting in catastrophic internal bleeding and death.
