Surgical coronary revascularization on-pump versus off-pump in patients with stenosis of the main tree of the left coronary artery and carotid stenosis

Abstract

OBJECTIVE: The aim of this study was to show perioperative complications of CABG procedure with and without cardiopulmonary bypass (CPB) in patients with combined coronary and carotid disease. PATIENTS AND METHODS: This retrospective survey included patients with left main stenosis greater than 50% and carotid stenosis over 50%, who had undergone CABG without carotid endarterectomy at the BH Heart Centre, from May 2009 to May 2014. The patients were divided into two groups according to the surgical method used. Group A consisted of 50 patients who underwent surgery without CPB and the second group of 50 patients with CPB, conformed according to gender, ejection fraction values, EuroSCORE and the number of bypass grafts performed. RESULTS: Analysis of the basic results indicates significant differences between the groups in the time spent on a respirator or time in the ICU, the amount of postoperative bleeding or compensated blood, as well as subsequent complications. The overall incidence of neurological complications showed a difference in the observed groups. CONCLUSION: With ever easier technical performance, complete planned revascularization and the quality of performed grafts, the conditions have been created for a comparative analysis. According to the results we can say that CABG without CPB has a number of advantages over the other method, in patients with the combined disease.
