Complications
By Mayo Clinic staff
Tears in the wall of the aorta (dissection) are the main complications of abdominal 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 or back pain
- Pain that radiates to your back or legs
- Sweatiness
- Clamminess
- Dizziness
- Nausea
- Vomiting
- Low blood pressure
- Fast pulse
- Loss of consciousness
- Shortness of breath
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 legs, toes, kidneys or abdominal organs.
