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. This elongation ...
A thoracic aortic aneurysm is an aortic aneurysm that presents primarily in the thorax. A thoracic aortic aneurysm is the "ballooning" of the upper aspect of the aorta, above the diaphragm. Untreated or unrecognized they can be fatal due to dissection or "popping" of the aneurysm leading to nearly instant death.
This sign should clue in a radiologist that there is an underlying injury. Some direct signs from a CT include having an intimal flap, irregularity of the shape of the aorta, filling defects secondary to a thrombus, or out pouching of the aorta. [2] However, non contrasted CT scans, chest X-rays, and transesophageal echos can also be used.
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. Specialty: Cardiology, Vascular surgery: Symptoms: abdominal pain and back pain: Complications: Hemorrhaging ...
The aortic wall dilatation at the commissural level causes the cusps to effectively shorten and prevent them from converging during systole, which results in aortic valve incompetence. The arch is typically spared from the aneurysmal process, though it may involve the entire ascending aorta. The ectatic aorta may experience dissections.
Aneurysm of the aortic sinus, also known as the sinus of Valsalva, is a rare abnormality of the aorta, the largest artery in the body. The aorta normally has three small pouches that sit directly above the aortic valve (the sinuses of Valsalva), and an aneurysm of one of these sinuses is a thin-walled swelling.
The aortic root is the portion of the aorta beginning at the aortic annulus and extending to the sinotubular junction. It is sometimes regarded as a part of the ascending aorta, [2] and sometimes regarded as a separate entity from the rest of the ascending aorta. [3]
The hemodynamics of the aorta is an ongoing field of research in which the goal is to identify what flow patterns and subsequent forces occur within the thoracic aorta. These patterns and forces are used to identify the presence and severity of cardiovascular diseases such as aortic aneurysm and atherosclerosis. [1]
