Cerebrovascular diseases (CVD) have remained an urgent medical and social problem of modern society over the past decades. One of the main pathogenetic subtype of ischemic stroke is cardioembolic stroke (CES), which accounts for 22-39% of all stroke subtypes. CES is characterized by the rapid development of neurological symptoms (80% of cases) with its maximum severity in the first 5 minutes (47-74%) and large and medium-sized ischemic infarcts, which in 85% of cases are located in the carotid artery system, more often in the left middle cerebral artery (MCA). The aim of the study: In this study, pathomorphological and clinical features of cardioembolic stroke, such as neurological signs, cerebral and myocardial infarcts in each sectional case, macroscopic and microscopic examinations were conducted and analyzed. Materials and methods: This study is based on the analysis of the results of a comprehensive clinical and pathomorphological examination. The patients were selected for 1 year. Clinical observations were carried out at the first clinic of the Tashkent Medical Academy in the Department of Intensive Neurology. The selection criteria were: 1) patients with ischemic stroke (IS) in combination with acute myocardial infarction and atrial fibrillation (main group); 2) persons with ischemic stroke (IS) without cardiac etiology (control group). Exclusion criteria: oncological and hematological diseases, severe renal and hepatic insufficiency. The analysis of 138 sectional cases with ischemic stroke and myocardial infarctions with atherostenosis of cerebral and coronary arteries were carried out. Autopsies of all deceased patients were performed in the laboratory of the Republican Center of Pathological Anatomy. Macroscopic examination of the brain in all 138 cases determined the type, magnitude, localization, degree of organization of each cerebral infarction and the number of cerebral infarctions in each sectional case. In each case, microscopic examination of the brain and cerebral arteries with atherosclerotic changes were also performed. For microscopic examination, preparations were cut from the area of cerebral infarction, as well as from the borderline zone with infarction. Areas of the brain were poured into paraffin wax, preparations with 5-7 microns thick were prepared into the blocks, which were stained with hematoxylin and eosin, cresyl violet according to the modified Nissl method, according to the methods of Wangizon, Weigert, as well as laxol blue durable. Results: Patients with IS and cardiac pathology – 120 people (group I) – 65 men and 55 women aged 48 to 77 years (62.6±5.8 years). Patients with IS without cardiac pathology – 160 people (group II). Of these, 83 men and 77 women aged 56 to 81 years (68.4±5.4 years). Among the deceased were 93 men and 45 women aged 45 to 93 years (average age 69 ± 11 years). The average age of men was 60 years, of women - 69 years. In 113 cases (82%), an autopsy revealed a combination of atherosclerosis with arterial hypertension, in 9 (6.5%) - atherosclerosis with diabetes mellitus. The cause of death in 64 patients (47%) was pronounced edema of the brain with dislocation and insertion of brain stem and parts of the cerebellum into the large occipital foramen due to infarction of the brain. All cases are divided into 3 groups: Group 1 includes cases with infarcts localized in the carotid system (68 cases), group 2 - cases with infarcts localized in the vertebrobasilar system (36 cases), group 3 - cases with infarcts localized in the arteries of both systems (34 cases). Conclusion: Brain infarctions in AS are characterized by great diversity regarding their localization; degree of organization, quantity; type; as well as: the main factors of their occurrence. The most numerous were medium infarcts and small deep infarcts, extensive, large infarcts and small superficial infarcts were less common. In our study, multiple atherosclerotic plaques, narrowing the lumen of the arteries by 30-80%, were found in 46% of cases. Moreover, in 28% of cases, plaques were located in different parts of the ICA - in the cerebral arteries of the MCA.
