The aorta is the largest artery. It originates in the heart’s left ventricle and delivers oxygenated blood to all parts of the body, including the vital organs, legs and feet. As the artery crosses the diaphragm, it is more specifically called the abdominal aorta.
Aortic Aneurysms are caused by progressive weakening of the aortic wall, which causes the vessel to expand or balloon out in a localized area. Aneurysms occur most often in the aorta, the main artery of the chest and abdome, and they can expand quietly, without any symptoms.
Aortic Aneurysms are typically classified according to their anatomical location. Abdominal aortic aneurysms are by far the most common affecting up to 5% of men over 60 years of age. Thoracic aortic aneurysms (TAA) are located in the portion of the aorta that is in the chest. There are various scans that can detect the exact position of a Thoracic Aortic Aneurysm (TAA) such as computerized tomography (CT) and magnetic resonance imaging (MRI).
Treatment options for Thoracic Aortic Aneurysms include observation and risk management, open surgical repair, and endovascular repair.
Vascular grafts are used for surgical repair of the aorta affected by aneurysm. This type of procedure is the current "Gold Standard" for aortic repair.
