BACKGROUND: Coronary artery bypass grafting (CABG) for hemodialysis patients is high risk compared with other patient groups. The aim of this study was to analyze the potential benefits of off-pump CABG for hemodialysis patients. METHODS: From April 1994 through December 2000, 26 hemodialysis patients underwent CABG. The off-pump group consisted of 15 patients operated on without a pump and the on-pump group consisted of 11 patients operated on with a pump. RESULTS: There was no difference between the two groups with regard to mean age, mean number of diseased vessels and mean number of anastomoses per patient. No patient died in either group during hospitalization. The postoperative complication rate was low in both groups. The postoperative ventilation time was shorter in the off-pump group (8.5 vs 26.1 hours, p < 0.001, respectively off-pump group vs on-pump group). The length of ICU stay was shorter in the off-pump group (1.7 vs 3.5 days, p = 0.01, respectively off-pump group vs on-pump group). The medial cost was lower in the off-pump group (26,200.80 dollars versus 44,024.10 dollars p = 0.0001 respectively off-pump group vs on-pump group). CONCLUSIONS: Off-pump CABG provided excellent less-invasive cardiac surgical results for dialysis patients.
