Brief Summary:
Little is known about how general anesthesia-induced decrease in cerebral blood flow in pediatric moyamoya pateints. We investigated this question in patients undergoing moyamoya surgery, hypothesizing that cardiorespiratory changes during this procedure would reduce cerebral perfusion.

Condition or disease Intervention/treatment
