Introduction: The use of radial artery in CABG has been controversial. This study contributes in the reassessment of RA usufulness. Material and Methods: The study comprises 143 patients, aged from 41 to 80 years, who underwent arterial revascularization of myocardium using radial artery, between 1997 and 2007. Only the patients with proximal anastomosis of radial artery to the aorta were included to the study group whereas performance of composite graft: radial artery – internal thoracic artery, was the exclusion criterion. In each case of expected disproportion between thickness of the aortic wall and the radial artery wall, the idea of direct anastomosis to the aorta was given up. Results: The in-hospital mortality was 3 patients (2,09%) and the perioperative myocardial infarction occurred in 4 patients (2,79%). In one patient, postoperative angiography showed a vasospasm of proximal portion of radial artery which yielded after the administration of intravenous nitroglycerine. As the rule, the anastomoses (single or sequential) were performed to the amputated or critically stenosed coronary vessels supplying significant regions of myocardium with expected good blood outflow. Conclusions: On the basis of their own experience, the authors believe that proximal anastomosis of the radial artery to the aorta is a safe procedure provided the commonly accepted rules of using radial artery as an aorto-coronary graft are obeyed.
