Treatment for arteritis, Takayasu, typically involves medications to reduce inflammation and suppress the immune system. These medications may include corticosteroids, such as prednisone, and immunosuppressants, such as methotrexate or azathioprine. Other treatments may include angioplasty, stenting, or bypass surgery to improve blood flow. In some cases, medications may be used to lower blood pressure or cholesterol levels. In severe cases, a procedure called an aortic arch reconstruction may be necessary.
