This publication is devoted to the problem of occurrence of acute cerebral circulatory disorder (STROKE) in operated patients as the most severe type of cerebral dysfunction that increases mortality and leads to patients’ disability, aggravating results of cardiosurgery treatment. The aim of our work was to determine the frequency, types, predictors of the risk of STROKE after coronary artery bypass grafting. The study included 844 patients who were operated in the National Amosov Institute of Cardiovascular Surgery of NAMS of Ukraine, Kyiv. Findings and conclusions. The incidence of acute disorders of cerebral circulation in the early postoperative period was 1.4 % (n = 12). In the structure of all strokes the STROKE of ischemic type were recorded at 83.3 % (n = 10) and that was the most frequent type of acute cerebral circulatory disorder (ACCD) in the early postoperative period. The most important risk factors for STROKE in the early postoperative period are: radionecrosis of the carotid arteries > 50 %, aortic atherosclerosis, atrial fibrillation in postoperative period, performing operations under extracorporeal circulation. All patients at high risk of the emergence of ACCD require careful assessment of the state of the aorta and carotid vessels before operation, improvement of surgical technique and the postoperative period according to the corresponding risk factors identified.
