Early and late outcomes of combined and staged surgeries in patients with concomitant atherosclerotic lesions of the coronary and brachiocephalic arteries

Objective. To study the early and late outcomes of surgical treatment of patients with concomitant atherosclerotic lesions of coronary and brachiocephalic arteries while choosing a treatment strategy based on the developed diff erentiated approach algorithm.Material and Methods. The study comprised 243 patients with combined atherosclerotic lesions of the coronary and carotid arteries examined during the period from 01.07.2014 to 01.01.2021. Patients underwent revascularization surgeries based on the algorithm for choosing the volume and stages of surgical intervention, which was previously developed in the Federal Center for Cardiovascular Surgery named after S.G. Sukhanov. A single-stage combined surgery of coronary artery bypass grafting (CABG) and carotid endarterectomy (CEE) was performed in 104 patients (42.8%); 139 patients (57.2%) received staged revascularization including 102 patients (73.4%) who received CABG as the fi rst step and 37 patients (26.6%) who received CEE as the fi rst step of surgery. The endpoints for both early and late results were death from all causes, stroke, transient ischemic attack (TIA), acute myocardial infarction (AMI), and combined endpoint that included all of the above. Average follow-up time was 41.1 ± 21.8 months.Results. No fatal outcomes were in any group during the early postoperative period. At the hospital stage, there were 5 cases (2.1%) of stroke, 1 case (0.4%) of TIA, and 3 cases (1.2%) of acute MI. Long-term results were evaluated in 225 patients (92.3%). The overall survival rate was 93.8%. There were 5 cases (2.4%) of MI, 11 cases (4.9%) of stroke, and 1 case (1.0%) of TIA. No signifi cant diff erences were observed in immediate and long-term endpoints between the groups of staged and combined interventions as compared to immediate (AMI: p = 0.680; TIA: p = 0.500; acute cerebrovascular events: p = 0.567; combined: p = 0.940) and long-term results (deaths: 0.860; AMI: p = 0.906; TIA: p = 0.528; acute cerebrovascular events: p = 0.378; combined: p = 0.669).Conclusion. Based on successful experience with treating the concomitant atherosclerotic lesions of the coronary and brachiocephalic arteries, the proposed algorithm allowed to perform safe procedures in both arterial basins and to achieve satisfactory results in in-hospital and long-term periods in the Federal Center for Cardiovascular Surgery named after S.G. Sukhanov (Perm).
