In the present study it was examined whether myocardial revascularization with multiple arterial grafts improves the prognosis of dialysis patients. The 20 subjects underwent coronary artery bypass grafting over 2 vessels (extra-corporeal circulation in 11 patients, off-pump bypass in 9 patients) and were divided into 2 groups according the number of arterial grafts. Group A consisted of 9 patients in whom more than 2 arterial grafts were used and Group B, 11 patients requiring 1 internal thoracic artery and additional saphenous vein grafts. The surgical procedure was examined, as well as the short-term and long-term results of both groups. There were no differences in the profiles of the 2 groups. The mean arterial graft number in group A was 2.2+/-0.6 and 1.0+/-0.0 in group B. There was neither mediastinitis nor brain complication in either group. There were no operative deaths in group A and 1 in group B. The 55-month actuarial survival rate including all deaths, and estimated by cardiac deaths, was, respectively, 0.53+/-0.21 and 0.80+/-0.18 in group A and 0.42+/-0.21 and 0.53+/-0.23 in group B. The survival rate estimated by cardiac death in group A was better, but there was not a significant difference. Myocardial revascularization with multiple arterial grafts for dialysis patients had good short-term results without increased operative risk and may improve the long-term results related to cardiac death. However, there was no significant difference in survival including all deaths because of the numerous non-cardiac deaths.
