Takayasu's arteritis

Overview

Takayasu's arteritis (tah-kah-YAH-sooz ahr-tuh-RIE-tis) is a rare type of vasculitis, a group of disorders that causes blood vessel inflammation. In Takayasu's arteritis, the inflammation damages the large artery that carries blood from your heart to the rest of your body (aorta) and its main branches.

The disease can lead to narrowed or blocked arteries, or to weakened artery walls that may bulge (aneurysm) and tear. It can also lead to arm or chest pain, high blood pressure, and eventually heart failure or stroke.

If you don't have symptoms, you may not need treatment. But most people with the disease need medications to control inflammation in the arteries and to prevent complications. Even with treatment, relapses are common, and your symptoms may come and go.
