Clinical Information

  • AAA, or abdominal aortic aneurysm, is a bulged or swollen aorta in the abdomen. If it grows in size and ruptures, it can cause life-threatening bleeding. 
  • Usually, patients don’t exhibit any symptoms, but as it worsens, they may feel a constant pain or pulse in their belly or back. 
  • Some common causes of AAA are high blood pressure, infection in the aorta, trauma, and atherosclerosis. People more likely to develop AAA are old, use tobacco, and have a family history of abdominal aortic aneurysms. 
  • A patient will undergo tests such as an ultrasound, CT scan, and MRI to diagnose AAA. 
  • Treatment includes monitoring and checkups. However, surgery may be required if it’s hugely swollen or has a high chance of rupturing. 

Synonyms Include:

  • Injury of the abdominal aorta
  • Leaking abdominal aortic aneurysm
  • Ruptured abdominal aortic aneurysm
  • Perforation of abdominal aorta
  • Abdominal aortic aneurysm without
