Studies on Cerebral Circulation and Metabolism in Hypertensive Diseases

IV. Cerebral Circulation and Metabolism in Hypertensive Postapoplectic Patients

Abstract

On 27 hypertensive postapoplet'c patients, 24 of which were complicated with hemiplegia and 3 of which were complicated with bilateral hemiplegia, cerebral circulation and metabolism were measured by N₂O method.
1. The disturbances in cerebral circulation and metabolism were exaggerated in those patients compared with hypertensive patients without apoplectic attack or normotensive persons.
2. No significant difference in cerebral circulation and metabolism could be detected between cerebral softning group and cerebral bleeding group. In patients with bilateral hemiplegia, which had cerebral attacks repeatedly, the most apparent disturbances could be found in cerebral circulation and metabolism.
3. A correlation to some extent could be detected between cerebral circulation and metabolism on the one hand and retinal findings or cardiac findings on the other, but it was not remarkable compared with that in hypertensive, non-apoplectic patients. No parallelism could be found between age and the cerebral circulation and metablism. Differences between 2 groups, with and without severe motor disturbances were not significant.
4. The cause of disturbances in cerebral. circulation and metabolism in postapoplectic patients was discussed, the correlation between those changes in them and clinical findings being closely examined.
