Thoracic Aortic Aneurysms

key information

source: Merck Manual

year: 2014

authors: John W. Hallett

summary/abstract:

A thoracic aortic diameter ≥ 50% larger than normal is considered an aneurysm (normal diameter varies by location). Most thoracic aortic aneurysms do not cause symptoms, although some patients have chest or back pain; other symptoms and signs are usually the result of complications (eg, dissection, compression of adjacent structures, thromboembolism, rupture). Risk of rupture is proportional to the size of the aneurysm. Diagnosis is made by ultrasonography or CT angiography. Treatment is endovascular stent grafting or surgery.
