Takayasu arteritis is an inflammation of the aorta and its major branches. The aorta is the artery that carries blood from the heart to the rest of the body.
The cause of Takayasu arteritis is unknown. The disease occurs mainly in children and women younger than 40. It is more common in people from of Asian or African descent.
Takayasu arteritis appears to be an autoimmune condition, which means the body's immune system mistakenly attacks healthy tissue. The condition may also involve other organ systems.

- Computed tomography (CT)
- X-ray of the chest
Treatment of Takayasu arteritis is difficult. However, people who have the right treatment can see positive results. It is important to identify the condition early.
Most people are first treated with high doses of steroids. Immunosuppressive drugs, such as azathioprine, mycophenolate, methotrexate, or leflunomide are often added.
Biologic agents including TNF inhibitors such as infliximab are recommended for people who do not improve with the previous treatment.
In difficult cases, tocilizumab or rituximab may be helpful.
Surgery is reserved for complications caused by narrowed arteries.
Surgery to open up narrowed arteries may be needed to supply blood or open up the constriction
This disease can be fatal without treatment. However, a combined treatment approach using medicines and surgery has lowered death rates. Adults have a better chance at survival than children.
- Blood clot
- Heart attack
- Heart failure
