Synopsis

Thoracic aortic aneurysm is an enlargement, dilatation, or ballooning of a segment of the thoracic aorta. Usually asymptomatic, complications can cause chest pain, hemoptysis, dyspnea, cough, dysphagia, wheezing, hoarseness, and elevated blood pressure. Heart failure can occur. Presence of aneurysm may be observed during chest x-ray, CT, or MRI. Acute aortic dissection and rupture are complications that are medical emergencies leading to almost instant death. Aortic rupture is characterized by intense pain, hypotension, and shock.

Risk factors are aneurysm-osteoarthritis syndrome, atherosclerosis, congenital heart defects (eg, bicuspid aortic valve), family history of aneurysmal disease, or genetic syndromes including Ehlers-Danlos, Loeys-Dietz, Marfan, and Turner syndromes.

Management depends on the location, shape, and size of aneurysm, as well as symptoms and concomitant cardiovascular disease. In asymptomatic patients, management may consist of blood pressure control with beta blockers, surveillance, and patient education to watch for early signs and symptoms of complications. Following complete evaluation and risk assessment, surgical repair or replacement may be undertaken.

For more information on the familial form, see OMIM.
