As part of the process of vascular disease, the wall of the aorta (the large blood vessel that carries blood away from the heart to the rest of the body) can become weak and dilate, and an aneurysm can form, either in the thoracic aorta in the chest or in the abdominal aorta in the belly. When these get large enough to threaten to rupture, a procedure is necessary to repair them, either a surgical procedure or a minimally invasive procedure in which the aorta is reconstructed from within using a device called a stent graft. We have been involved from the very beginning of this developing field. AAA web brochure Click here for more information.
