Vasculitis

Complications

Vasculitis complications 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 the condition. 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).
  • Vision loss or blindness. This is a possible complication of untreated giant cell arteritis.
  • Infections. Some of the medications used to treat vasculitis may weaken your immune system. This can make you more prone to infections.
