From 2000 to 2011, a total of 52 patients with combined atherosclerotic lesions of the coronary and brachiocephalic arteries were subjected to a single-stage operation. Depending on the type of operative intervention, all patients were subdivided into two groups: Group One comprising 13 patients who underwent coronary artery bypass grafting (CABG) in a combination with simultaneous stenting of the internal carotid artery, and Group Two consisting of 39 patients subjected to CABG with simultaneous carotid endarterectomy. Assessing the intraoperative parameters revealed that in Group One patients the average duration of operations was significantly lower (179.6±6.4 minutes versus 273.2±5.6 minutes in Group Two, p<0.001) and the time of assisted circulation was less than in Group Two, averaging 75.9±4.5 versus 115.2±3.8 minutes, respectively (p<0.001). The duration of pulmonary artificial ventilation in Group One patients was less than in Group Two patients (9.7±2.6 hours versus 25±4.8 hours, respectively, p<0.01). Also the duration of staying in the critical care unit was shorter in Group One patients than in Group Two patients (21.5±3.3 versus 82.1±8.0 hours, respectively, p<0.001). The overall hospital mortality rate amounted to 12.8% (5 patients), with all deaths having occurred in Group Two. The lethal outcomes were caused by acute myocardial infarction in three cases, one patient died of progressing multiple-organ failure on the background of acute impairment of cerebral circulation and one death was caused by thrombosis of the mesenteric artery with the development of intestinal gangrene and peritonitis. In the structure of hospital complications cardiac insufficiency was prevalent (23.1% and 59.0% for Groups One and Group Two patients, respectively, p<0.05). Analysing the incidence and structure of other postoperative complications revealed no statistically significant differences between the groups. Our study demonstrated that using surgical methods of treatment of patients with haemodynamically significant stenoses of the coronary and brachiocephalic arteries makes it possible to increase the overall survival rate in patients suffering this disease and to decrease the incidence rate of ischaemic impairments of the coronary and cerebral circulation. The hybrid method of treatment on arteries of various vascular basins may be an alternative to carotid endarterectomy and CABG, especially in patients running high surgical risk.
