ETIOLOGICAL ASPECTS OF ISCHEMIC BRAIN INFARCTION

Diseases of the cardiovascular system are the main cause of death in the world's population. Among cardiovascular diseases, ischemic brain infarction is the leading cause of death and ranks first in the disability of the population. Thus, according to the National Association for stroke control, only 10% of the population who have suffered a stroke can return to normal life without additional medical and social assistance. The purpose of this study is to study the etiological aspects of ischemic brain infarction based on clinical and morphological studies. Autopsy reports of men who died from ischemic brain infarction with an age range of 58 to 69 years were analyzed. It was found that the main causes of ischemic brain infarction were a combination of factors: arterial hypertension of the 3rd degree with a tendency to hypertensive crises, ischemic heart disease and atherosclerosis of the cerebral arteries, whose obliteration varied from 30% to 75%. Acute violation of cerebral circulation often occurred in the right hemisphere in the middle cerebral artery basin, which led to the appearance of a focus of necrosis in the parietal and temporal lobes. At the same time, the clinical manifestations were quite similar - these are sensitive, visual, speech, motor and sensory disorders that have a progressive character. The intensity, severity and prevalence of certain neurological disorders depends on the location and volume of the lesion. The volume of the necrosis focus was in the range of 1.5 to 12 centimeters and correlated with the degree of obliteration of the brain arteries.
