The Moyamoya syndrome and the neurosurgeon.
Three cases (two children, one adult) presenting the angiographic features of the Moyamoya syndrome are reported, and the variety of the arterial collateral system is described. If there is a progressive neurological deterioration as a consequence of an inadequate collateral circulation, the creation of a new collateral vascular channel by way of anastomosis between the superficial temporal artery and a branch of the middle cerebral artery is proposed.
