Overview
Hypertension and cigarette smoking are the most important risk factors, though the importance of genetic factors in the development of thoracic aortic aneurysm (such as familial thoracic aortic aneurysm; familial aortic dissection) has been increasingly recognized. Approximately 10% of patients may have other family members who have aortic aneurysms. It is also important to note that individuals with a history of aneurysms in other parts of the body have a higher chance of developing a thoracic aortic aneurysm.[1]
Risk Factors
Thoracic aortic aneurysm risk factors include:[2][3]
- Smoking or chewing tobacco
- High blood pressure
- Bicuspid aortic valves
- Atherosclerosis (buildup of plaque in the arteries that can damage the lining)
- Gender: Aortic aneurysms are three times more prevalent in males versus females.
- Race: Aortic aneurysms are more frequent in Caucasian individuals versus other races.
- Individuals who have a family history of aortic aneurysms have a much higher risk of rupture and tend to develop aneurysms at a younger age.
- Chronic obstructive pulmonary disease
- Previous repair of a thoracic aorta aneurysm
- Turners syndrome
