Tears in the wall of the aorta (dissection) and rupture of the aorta are the main complications of thoracic aortic aneurysm. A ruptured aortic aneurysm can lead to life-threatening internal bleeding. In general, the larger the aneurysm, the greater the risk of rupture.

Signs and symptoms that your thoracic aortic aneurysm has burst include:

  • Sudden, intense and persistent chest or back pain
  • Pain that radiates to your back
  • Trouble breathing
  • Low blood pressure
  • Loss of consciousness
  • Shortness of breath
  • Weakness or paralysis of one side of the body, difficulty speaking, or other signs of stroke

Blood clot risk

Another complication of aortic aneurysms is the risk of blood clots. Small blood clots can develop in the area of the aortic aneurysm. If a blood clot breaks loose from the inside wall of an aneurysm, it can block a blood vessel elsewhere in your body, possibly causing serious complications.
