What is Takayasu's arteritis?
A person with Takayasu's arteritis has a rare illness that causes inflammation of the aorta, as well as inflammation of the arteries that branch off the aorta. The aorta is the largest artery in the body. Blood passes from the heart and through the aorta, before it is delivered to the rest of the body. Arteries that branch off the aorta supply blood to the heart, brain, arms, legs, liver, spleen, intestine and kidneys. Takayasu's arteritis results from an abnormal immune system, which normally fights infection. The immune system mistakenly attacks normal arteries, causing inflammation and narrowing of the arteries. The cause of the abnormal immune system in Takayasu's arteritis is unknown.

What are the symptoms of Takayasu's arteritis?
Symptoms of Takayasu's arteritis may include chest pain, abdominal pain, dizziness, fatigue, fainting, blurry vision, vomiting, muscle weakness, and leg pain that worsen with physical activity.

How does the doctor treat Takayasu's arteritis?
Treatment for Takayasu's arteritis may include oral corticosteroid medications, medications that suppress the immune system, nonsteroidal anti-inflammatory medications for pain, and surgery.
