In rare cases of stroke in children and youths, a likely cause is the idiopathic disease moyamoya, characterized by the slow and progressive stenosis and occlusion of the internal carotid artery and the arteries of the circle of Willis. A result of these stenoses is the formation of collaterals that are typically small and fragile, and liable to rupture. While there is no cure for moyamoya, a variety of surgical procedures can be performed to reestablish and maintain adequate blood supply to the affected brain areas. The procedures described here include various revascularization techniques and recommended bypasses. Key Features: With contributions from the world's most renowned bypass surgeons Perioperative management and considerations An overall practical approach to this painstaking high-end surgery Detailed criteria for analyzing the situation and choosing the appropriate procedure General principles of bypass surgery, direct and indirect revascularization, and combined revascularization techniques Step-by-step descriptions of these procedures Rescue strategies when repeat surgery is necessary Surgical Techniques in Moyamoya Vasculopathy is an indispensable guide for the experienced neurovascular surgeon.
