Complications of vasculitis depend on the type and severity of your condition. Or they may be related to side effects of the prescription medications you use to treat it. Complications of vasculitis include:

  • Organ damage. Some types of vasculitis can be severe, causing damage to major organs.
  • Blood clots and aneurysms. A blood clot may form in a blood vessel, obstructing blood flow. Rarely, vasculitis will cause a blood vessel to weaken and bulge, forming an aneurysm (AN-yoo-riz-um). You may need surgery to remove an aneurysm.
  • Vision loss or blindness. This is a possible complication if giant cell arteritis is left untreated.
  • Infections. These include serious and life-threatening conditions, such as pneumonia and blood infection (sepsis).
