A thoracic aortic aneurysm is an abnormal widening or ballooning of a portion of the aorta caused by weakness in the wall of the artery. Atherosclerosis is by far the most common cause, although it may be caused by a variety of conditions, including high blood pressure, congenital disorders (such as Marfan's syndrome) or trauma.


Most patients have no symptoms until the aneurysm begins to leak or expand. Most non-leaking thoracic aortic aneurysms are detected by tests, such as a chest X-ray or a chest computed tomography (CT) scan that are being run for other reasons. Chest or back pain may indicate acute expansion or leakage of the aneurysm.
