Complications
By Mayo Clinic staff
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 aortic aneurysm has burst include:
- Sudden, intense and persistent abdominal, chest or back pain
- Pain that radiates to your back or legs
- Sweatiness
- Clamminess
- Dizziness
- Low blood pressure
- Fast pulse
- 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 and blocks a blood vessel elsewhere in your body, it can cause pain or block the blood flow to the brain, legs, toes or abdominal organs.
