CT
Sagittal C+ arterial phase
When is the risk of rupture significantly elevated in thoracic aortic aneurysms?
When the diameter reaches 5 - 6 cm.
What are the treatment options for thoracic aortic aneurysms?
Treatment options include open repair surgery and interventional endovascular repair. In general, when possible, endovascular repair is the treatment of choice, with reduced morbidity and mortality.
The para-sagittal multi-planar reconstruction from the CT-angiography nicely shows the ascending aortic aneurysm with normal width of the rest of the thoracic aorta.
