Off-pump coronary artery bypass surgery in patients with chronic renal failure

Abstract

Objective: Patients with dialysis-dependent renal disease frequently present with coronary artery disease. These patients are considered to be at high risk for coronary artery bypass grafting. Therefore, off-pump coronary artery surgery may become a good option for these patients. Off-pump coronary artery bypass surgery in patients with dialysis-dependent renal failure was retrospectively reviewed in this study. Methods: From March 2001 through May 2005, we performed off-pump coronary bypass grafting in 10 patients with dialysis-dependent renal failure. Coronary artery bypass grafting was performed on beating heart in all of the patients. The patients were evaluated for perioperative variables and postoperative outcomes. Results: Mean age was 58.7±8.9 years with a range between 45 to 76 years. Eight of the patients were male and two were female. No perioperative and postoperative deaths or ischemic cardiac events were observed. Anginal symptoms of the patients were relieved during the postoperative period. Functional status of the patients was improved postoperatively. None of the patients needed revision due to hemorrhage. Mean distal anastomosis number was 1.8±0.6. Mean intensive care unit stay was 1.8±0.8 days and hospital stay was 5.3±0.9 days. Conclusion: Off-pump coronary artery bypass grafting can be performed with good clinical results. We believe that off-pump coronary revascularization is a good option in patients with dialysis-dependent renal failure.
