The remote results of treatment of ischemic stroke conditioned by atherosclerotic affection of carotid arteries

Abstract

The ischemic stroke is a disease that leads to dysfunctions in life of any individual. The mortality rate of cerebral infarcts reaches up to 39%. Besides, the most acute period of an ischemic stroke, which lasts up to 5-7 days, is especially problematic and is characterized by the highest mortality. The first day of disease results in 21.74% of deaths (out of the total annual number of deaths). The article presents the results of the analysis of treatment of the patients with ischemic stroke caused by the atherosclerosis of brachiocephalic arteries. The role of endovascular technologies in the treatment of the acute cerebrovascular cases has not been fully revealed. The retrospective analysis of treatment of 171 patients with atherosclerotic subtype of ischemic stroke was carried out. The patients were distributed in two groups: in the first group (83 patients) the applied conservative therapy was supplemented by endovascular intervention during the acute period of ischemic insult; in the second group (88 patients) the conservative therapy alone was applied. Both groups were comparable in terms of gender, age and associated diseases. The risk factors of ischemic insult were analyzed such as IHD that requires surgery; hypertensive disease; hypercholesterolemia; ischemic insult in medical history; heart dysrhythmia; diabetes mellitus. All patients had more than one risk factor. There mortality, incapacitation, degree of neurological impairment, frequency of symptoms of hemorrhagic suffusion and of hemorrhagic transformation were analyzed. The remote results were analyzed in sampling of 54 patients: 32 patients from the first group, 22 patients from the second group. The quality of life was measured using technique of non-specific survey SF-36 when its 36 items were grouped into eight scales: physical functioning, role activity, body pain, general health, vitality, social functioning, emotional state, psychological health. The degree of incapacitation was measured with the modified Rankin scale, the quality of life was examined with the SF-36 survey, the survival rate was measured with the Kaplan-Meier estimator. The statistical analysis was carried out with the help of the Statistica 6.0 software.
