Coronary artery bypass grafting in patients with dialysis-dependent renal failure.

The aim of this study was to define short- and long-term results of coronary artery bypass grafting (CABG) in dialysis patients. A retrospective review was carried out on 73 consecutive patients dependent on chronic dialysis who underwent CABG. In 63 isolated CABGs, 9 operations were performed under normal beating heart because of severe atherosclerotic changes in the ascending aorta or carotid arteries. The operative mortality (30 days' mortality) was 4.1%, and causes of death were closely related to cardiopulmonary bypass use. In the last 29 operations after introduction of the beating heart bypass, no hospital deaths occurred. The actual survival rates dropped to 45% at 70 months mainly for noncardiac late death. CABG for dialysis patients as undertaken with an acceptable operative risk. Extended application of beating heart bypass to these patients may produce further positive early results.
