The only proven, long-term treatment for Moyamoya disease is surgery. The goal of surgery is to create a healthy, new supply of blood for the part of the brain affected by this disease.
There are two kinds of surgery for Moyamoya disease:
The surgeon connects a blood vessel from outside the skull (usually the artery by the temple) to a blood vessel inside the skull (middle cerebral artery). This creates an immediate new pathway for the blood to flow.
This type of surgery involves laying an artery, muscle or other tissue on the surface of the brain. Over time, new blood vessels form and branch off from the new artery, leading to improved blood flow to the brain.
