Giant cell arteritis can cause the following complications:

  • Blindness. Diminished blood flow to your eyes can cause sudden, painless vision loss in one or, rarely, both eyes. Loss of vision is usually permanent.
  • Aortic aneurysm. An aneurysm is a bulge that forms in a weakened blood vessel, usually in the aorta, the large artery that runs down the center of your chest and abdomen. An aortic aneurysm may burst, causing life-threatening internal bleeding. Because this complication may occur even years after the initial diagnosis of giant cell arteritis, your doctor may monitor the health of your aorta with annual chest X-rays or other imaging tests, such as ultrasound and CT.
  • Stroke. This is an uncommon complication of giant cell arteritis.
