Сравнительный анализ асимметричности мозгового кровообращения по данным перфузионной компьютерной томографии при инфарктах больших полушарий головного мозга и дисциркуляторной энцефалопатии

Abstract

Currently a problem of timely diagnostics and treatment of disorders of cerebral circulation is one of the most important for medicine, as strokes and chronic brain ischemia occupy a significant place among the diseases leading to mortality and disability of population. Computed tomography is one of the leading diagnostics of cerebro-vascular disorders. Today, the diagnostic capabilities of perfusion computed tomography, especially in the field of subtle changes in perfusion in infected and in the contralateral hemispheres of the brain are poorly understood and aren’t used in full. The relevance and scientific novelty of this research is not in doubt. Based on the data of 87 patients with ischemic infarction of the cerebral hemispheres of the brain and vascular encephalopathy, a comparative analysis of blood flow in the affected and contralateral hemispheres, was carried out. The degree of asymmetry of blood flow depending on the phase of development of ischemic stroke and chronic brain ischemia was evaluated. The studies have shown that the relative indicator of inter-hemispheric asymmetry is reduced in the course of development of cerebral infarction, reaching minimum values of dyscirculatory encephalopathy. The author substantiates the practical use of the proposed indicator of inter-hemispheric asymmetry in the evaluation of the degree of chronic ischemic disturbances of cerebral blood flow.
