Artery of Percheron is a rare anatomical variant in which vast areas of the midbrain and thalamus have a single source of blood supply. This case report presents a 45-years old female patient with bilateral thalamic stroke due to Percheron artery occlusion, with a combination of hereditary thrombophilia and patent foramen ovale as the risk factors. Modern approaches to the diagnosis and secondary prevention of this pathology are also discussed herein.

Succinate is an endogenous substrate of the human organism that participates in various redox processes, reactions of the Krebs cycle, and the mitochondrial oxidation chain. This universal intracellular metabolite plays an important role in the regulation of physiological, metabolic, and energy-producing processes. The article discusses the issues of neuroplasticity, the importance of correction of energy deficiency, oxidative stress and other pathophysiological processes, and maintenance of adequate functional activity of neuronal structures after cerebral circulation disorders. The problems of neuroprotective therapy in ischemic stroke, which is pathogenetically justified in all stages of restorative treatment after cerebrovascular accident, are considered. Cytoflavin is one of the most studied original cytoprotectors, which demonstrated safety, efficacy, and good tolerability. Results of numerous clinical trials revealed significant positive clinical and morphological dynamics of cytoflavin administration in patients after ischemic stroke.

Post-stroke cognitive impairment (PSCI) is often characterized by a complex prognosis of neurorehabilitation, insufficient restoration of the functional status of patients, and a high risk of recurrent strokes and disability, which determines considerable health care costs. Objective: to carry out a comparative pharmacoeconomic analysis of the use of actovegin (Takeda Pharmaceuticals, Switzerland) in Russian patients with PSCI. Patients and methods. The investigation was conducted using a modeling method to determine the cost-effectiveness of competing treatment strategies: standard patient management; standard patient management and use of actovegin. Data from the ARTEMIDA clinical trial were used. Results and discussion. The use of actovegin was economically justified, which was expressed in more preferable cost-effectiveness indicators. Also, the use of actovegin in patients significantly reduced the risk of post-stroke dementia and, accordingly, the cost of treatment in future periods. Conclusion. The findings data indicate the clinical and economic feasibility of using actovegin in patients with PSCI.

Interleukin 6 (IL-6) plays an important role in the pathogenesis of ischemic stroke (IS), exerting a modulating effect on a number of processes that determine the outcome of this disease. Objective: to investigate the peripheral blood levels of IL-6 in patients in the acute period of different IS pathogenetic subtypes and its effect on recovery rates. Patients and methods. The study enrolled 155 patients (74 men and 81 women; mean age, 63.8 years). A control group consisted of 28 people without IS. Pathogenetic subtype II was established in accordance with the TOAST (Trial of Org 10172 in Acute Stroke Treatment) criteria on the basis of their clinical picture and the data of computed tomography or magnetic resonance imaging and ultrasonography of the main arteries of the head. The severity of a patient's condition and a focal neurological defect and the time course of clinical changes after stroke were determined using the National Institutes of Health Stroke Scale (NIHSS). An enzyme immunoassay (EIA) was used to measure IL-6 levels on days 1, 7, and 21 after onset of IS. An enzyme immunoassay (EIA) was used to measure IL-6 levels on days 1, 7, and 21 after onset of IS. Results. In the acute period of IS, there were significantly elevated levels of IL-6. The latter reached its highest values on day 7 in patients with the atherothrombotic pathogenetic subtype of IS. On day 7 of the study, the peak concentration of IL6 was typical for patients with all subtypes of IS, except for lacunar stroke. After its increase on day 1 of the study, the IL6 level in patients with lacunar stroke did not change significantly in all other periods. In acute IS, the concentration of IL-6 was significantly influenced by the following cardiovascular risk factors: hypercholesterolemia of days 1, 7 (p<0.01) and 21 (p<0.05), hypertension in day 1 (p<0.05), diabetes mellitus on days 1 and 7 (p<0.05), and coronary heart disease in all the study periods (p<0.01). The IL-6 concentration significantly correlated with the severity of neurological defect, but did not significantly affect the rate of recovery in the patient with acute IS. Conclusion. IL-6 was established to be of prognostic value for the outcome of acute IS on day 7. The rate of recovery can be used to identify targets for therapeutic intervention.

© 2018 Stolichnaya Izdatelskaya Kompaniya. The review focuses on the impairment of the carotid, coronary arteries and lower-extremity arterial disease. Systemic involvement of various vascular beds in atherogenesis is emphasized. Epidemiological characteristics of morbidity and mortality from the main clinical manifestations of atherosclerosis - ischemic stroke, ischemic heart disease and lower-extremity arterial disease are given. The current principles of drug therapy are considered from the point of view of improving the prognosis and eliminating ischemia. The basic positions of International and Russian clinical recommendations on the management of patients with the presence of certain clinical manifestations of atherosclerosis are discussed. Detailed administration schemes and the preferred doses of statins and antiplatelet agents depending on the localization of atherosclerotic lesion and the severity of stenosis are described. The target blood lipids levels in the treatment with statins are given. The advantages of statins as drugs that reduce the risk of cardiovascular complications are presented. Current data on the pattern of antiplatelet use, including acetylsalicylic acid, in individuals with clinical manifestations of atherosclerosis are given. The principal tactic of dual antiplatelet therapy and schemes of its use in patients undergoing percutaneous coronary intervention, coronary artery bypass surgery and in individuals with a history of acute coronary disorders are considered..

This paper presents a literature review considering the role and mechanism of apoptosis in the pathogenesis of ischemic stroke (IS). The authors introduce a new concept: the functional request of the patient as a set of external (the nature and intensity of rehabilitation measures, characteristics of everyday life, diet, etc.) and internal (genetic factors, internal picture of the disease, availability of rental and other psychological facilities and etc.) attributes. This concept allows a new angle in understanding the pathogenesis of IS and creates fundamental and clinical potential for more successful approaches to therapy and rehabilitation after IS.
