(HealthDay News) -- Aneurysm is the medical term for a bulging area of an artery that's stretched out like a balloon. It occurs when the artery wall becomes weak or damaged.

The U.S. National Heart, Lung, and Blood Institute lists these possible causes of an aneurysm:

  • Being older.
  • Having plaque buildup inside an artery (atherosclerosis).
  • Having high blood pressure.
  • Being a smoker.
  • Having an infection or illness that leads to inflammation of the blood vessels.
  • Having a family history of aneurysm.
  • Having a genetic condition that weakens blood vessels.
  • Sustaining an injury or trauma, such as being in a car accident.
