Overview
Natural History
Complications
Dissection
Aortic dissection is one of the most feared complications of an aortic aneurysm. Patients who have a prior dissection as a cause of an aneurysm are at increased risk of rapid expansion and re-dissection of the aneurysm.
Prognosis
The principal causes of death due to thoracic aneurysmal disease are dissection and rupture. Once rupture occurs, the mortality rate is 50–80%, and most deaths in patients with the Marfan syndrome are the result of aortic disease. It is estimated that up to 47,000 people die each year from all types of aortic disease.
Factors associated with a worse prognosis are:
- Diastolic dysfunction
- Traumatic aneurysm
- Associated coronary artery disease
- Carotid artery disease
