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.
