title: Some observations in progressive arterial occlusions in children and young adolescents: (Moyamoya disease).
abstract: In "primary arterial occlusions of children", an unusual collateral circulation has been described first by Japanese, and later by others worldwide. As experience was gained some workers started to realize that the "typical angiographic appearance" could be found in several disease entities. It thus became evident that angiographic differentiation is important. In this communication we wish to discuss this entity and outline its significance as well as emphasize the pitfalls.
