1 - What is an abdominal aortic aneurysm?

  • The aorta is the main blood vessel that supplies blood to the body.
  • Sometimes the wall of the aorta in the abdomen can become weak and stretch to form an aneurysm. When this happens, there is a risk that the aorta may split or tear (rupture).
  • A ruptured AAA can lead to serious blood loss that will need immediate emergency treatment.
  • Not every AAA will rupture, but if it does the chances of getting to hospital and surviving surgery are very poor.
