Duke is a leading regional referral center for moyamoya disease, a rare condition in which large arteries thicken and reduce the brain's blood supply. Our specialists surgically bypass affected arteries to restore blood flow.

Experts in moyamoya disease

Moyamoya is a potentially devastating condition that occurs when the walls of the brain's large arteries thicken, and and gradually shut down blood flow. As the large arteries thicken, the brain recruits smaller vessels to distribute blood, which can increase your risk for stroke.  As a result, blood leaks into the brain from the smaller vessels.  The small vessels are often described during imaging procedures as  a puff of smoke, which is why the disease is called moyamoya. Moyamoya is the Japanese term for “puff of smoke.”
