Extract

While a vast literature refers to anomalies in various arteries of the brain, there are only a few reports concerning anatomical changes of vessels following altered circulatory conditions. Critchley mentions in his study of the anterior cerebral artery and its syndromes, an observation in which an arterio-sclerotic anterior cerebral artery of one side was so small as to be incapable of maintaining an adequate circulation, so that by way of an abnormally large anterior communicating artery the opposite anterior cerebral supplied both hemispheres. Critchley adds to that case several similar observations from the literature. The application of arteriography to circulatory disturbances has directed attention to analogous cases. Thus Moniz reported several observations in which a closure of the carotid artery of one side led to a distension of the anterior communicating in order to establish collateral circulation. The same mechanism appeared to be effective in the following two cases which we met in the course of our studies on brain vessels.
