Aortic unfolding is an abnormality visible on a chest X-ray, that shows widening of the mediastinum which may mimic the appearance of a thoracic aortic aneurysm. [1]With aging, the ascending portion of the thoracic aorta increases in length by approximately 12% per decade, whereas the diameter increases by just 3% per decade.
Aortic aneurysm; Figure A shows a normal aorta. Figure B shows a thoracic aortic aneurysm (which is located behind the heart). Figure C shows an abdominal aortic aneurysm located below the arteries that supply blood to the kidneys.
The aorta must be clamped during the repair, denying blood to the abdominal organs and sections of the spinal cord; this can cause a range of complications. As it is essential to perform the critical part of the operation quickly, the incision is typically made large enough to facilitate the fastest repair.

The size cut off for aortic aneurysm is crucial to its treatment. A thoracic aorta greater than 4.5 cm is generally defined as aneurysmal, while a size greater than 5.5 cm is the distinction for treatment, which can be either endovascular or surgical, with the former reserved for pathology at the descending aorta.

The aorta (/ eɪ ˈ ɔːr t ə / ay-OR-tə; pl.: aortas or aortae) is the main and largest artery in the human body, originating from the left ventricle of the heart, branching upwards immediately after, and extending down to the abdomen, where it splits at the aortic bifurcation into two smaller arteries (the common iliac arteries).
In front of the thoracic aorta lies the root of the left lung, the pericardium, the esophagus, and the diaphragm. The esophagus, which is covered by a nerve plexus lies to the right of the descending thoracic aorta. Lower, the esophagus passes in front of the aorta, and ultimately is situated on the left.
