Encephalogaleosynangiosis – refers to a revascularization technique used to treat Moyamoya Disease or cerebral ischemia. Technique is to expose the cortical surface fo the brain after dissecting a portion of galea free from its overlying scalp. The freed galea is then laid down over the cortical surface to remain in contact with it after closure fo the surgical incision. Over time vascular branching from the galea into the ischemic cortical surface results in revascularization.
