Moyamoya disease is a cerebrovascular disease named after its angiographic image diagnosis, the etiology of which is not known and which is characterized by the chronic progressive stenosis of the main internal cerebral arteries that make up the Willis polygon. Ischemic symptoms are at the forefront in this disease which is more frequently observed in children. The definitive treatment of this disease is surgery and cerebral ischemia is a complication that can develop frequently during surgery. That is why, care during the perioperative period is very important. Perioperative anesthetic goal is to ensure the balance between the delivery of oxygen to the brain and the consumption of oxygen. The objective of this presentation is to discuss the anesthesia application in a child case who underwent encephalo-dura-arterio-cynangiozis (EDAS) surgery because of a 15 month moyamoya disease.
