Takayasu Arteritis

Takayasu arteritis (TAK) is a rare condition that involves inflammation of the lining of large blood vessels called arteries. It is sometimes called aortic arch syndrome.

This inflammation caused by Takayasu Arteritis can seriously damage important arteries including those that supply blood to the heart and lungs.

Takayasu Arteritis belongs to a family of arthritic diseases called vasculitis. The word vasculitis means inflammation of blood vessels.

Some people who get the disease go into remission after successful treatment and eventually no longer require medication. In others, the condition behaves more like a chronic (long-term) disease that must be controlled with medication on an ongoing basis.

Autoimmune Disease

Takayasu Arteritis is an autoimmune disease, which means it occurs when the body’s immune system attacks its own healthy cells and tissues. The reason why it does this is not well understood.

Importance of Treatment

It is very important to treat Takayasu arteritis quickly and aggressively to control inflammation that can damage the arteries.

Takayasu arteritis is considered a medical emergency. If left untreated it can lead to serious complications including loss of vision and stroke.

Who Gets Takayasu Arteritis

Takayasu arteritis mostly affects young people, primarily between the ages of 10 and 40 years. It is 8 times more common in young women than young men, and slightly more common in people of Asian or African descent.
