Thoracic aneurysms are less common than an abdominal aortic aneurysm. Whenever rupture of thoracic aneurysm takes place, patients usually deal with excruciating … Managing Incidental Findings on Thoracic CT: Mediastinal and Cardiovascular Findings. Most commonly occur in 50 to 60-year-old age group and incidence is estimated at ~7.5 per 100,000 patient-years 8. The aorta . Rouchaud A, Brandt MD, Rydberg AM et-al. Transesophageal echocardiography can visualize much of the descending aorta, but due to its invasive nature is not routinely used. 9. Both CTA and MRA are the modalities of choice to image this condition. Acquisitions capable of being reformatted in three dimensions are essential to allow for accurate luminal measurement 2. Thanks for your vote! Aortic Aneurysm, Abdominal: An abnormal balloon- or sac-like dilatation in the wall of the ABDOMINAL AORTA which gives rise to the visceral, the parietal, and the terminal (iliac) branches below the aortic hiatus at the diaphragm.

Aortic Aneurysm, Thoracic An abnormal balloon- or sac-like dilatation in the wall of the THORACIC AORTA. Mild to moderate aneurysmal dilatation can usually be treated conservatively and monitored. Aneurysms that occur in the part of the aorta within the abdomen are called abdominal aortic aneurysms. Traumatic thoracic aortic aneurysm: treatment with endovascular stent-grafts. Radiographics. MRI has the advantage of not requiring ionizing radiation or large volumes of iodinated contrast 2. The main predictors of rupture are the size and speed of growth 3. 2012;109 (13): 227-33. They are most commonly located in the abdominal aorta, but can also be located in the thoracic aorta. Thoracic aortic aneurysm A thoracic aortic aneurysm is a weakened area in the upper part of the aorta - the major blood vessel that feeds blood to the body. Thoracic aortic aneurysms are relatively uncommon compared to abdominal aortic aneurysms. Radiology. Distension can be: Saccular (ampullar) when an excavation appears; Diffuse, when there is an equal expansion of the vessel distension at its certain length ; Aortic aneurysm causes. This leaflet explains about thoracic aortic aneurysms. A thoracic aortic aneurysm is a blood-filled bulge or ballooning in a part of the aorta that runs through the chest. Specifically, the thoracic aorta is that part of the aorta that starts after the arch of the aorta and runs down to the diaphragm, the great muscle that separates the chest from the abdomen.
