Thoracic aortic aneurysm risk factors include:

  • Age. Thoracic aortic aneurysms occur most often in people age 65 and older.
  • Tobacco use. Tobacco use is a strong risk factor for the development of an aortic aneurysm. The longer you've smoked or chewed tobacco, the greater your risk.
  • High blood pressure. Increased blood pressure damages the blood vessels in the body, raising your chances of developing an aneurysm.
  • Buildup of plaques in your arteries (atherosclerosis). The buildup of fat and other substances that can damage the lining of a blood vessel (atherosclerosis) increases your risk of an aneurysm.
  • Family history. People who have a family history of aortic aneurysm are at increased risk of having one. People who have a family history of aneurysms tend to develop aneurysms at a younger age and are at higher risk of rupture.
  • Connective tissue disorders. If you have a connective tissue disorder, such as Marfan syndrome or Ehlers-Danlos syndrome, you have a significantly higher risk of a thoracic aortic aneurysm.
