[Cerebral ischemia in young patients].

The clinical, angiographic and computed tomography (CT) examinations of 19 patients aged from 12 to 30 years with signs of ischaemic brain syndrome are presented. On the basis of these examinations and data obtained from literature it is supposed that in a majority of patients the disease is caused by basal arteriopathies + i.e. pathological changes in the wall of cerebral arteries, mainly of the circulus Willis. The features distinguishing this syndrome from ischaemic disease in adults are presented and discussed. These are first of all: sudden onset connected with physical effort, deep neurological deficit, narrowing or occlusion of basal cerebral arteries seen in angiography and signs of ischaemia within deep cerebral structures visible in CT. The methods of treatment are discussed, mainly STA-MCA anastomosis used in most cases. The results of treatment are discussed. Finally the problem of the cerebral ischaemic syndrome in young people is presented from the point of view of haemodynamics, principally in the aspect of haemodynamic reserve of cerebral blood flow.
