You can help prepare for a visit to the Moyamoya Program by gathering your child’s images, medical records, and a written medical history before your child’s visit.
In moyamoya, the walls of the internal carotid arteries — the vessels that supply blood to important areas of the brain — become thickened and narrowed. This causes the flow of oxygen-rich blood to the child's brain to gradually slow down, making patients more prone to strokes or other ischemic symptoms. MRIs and diagnostic angiograms are typically ordered for patients to confirm diagnosis and plan for surgery.
