[Coronary artery bypass grafting in patients with dialysis-dependent renal failure].
From January 1995 to May 2003, 36 patients with dialysis-dependent renal failure underwent coronary artery bypass grafting. We performed the operation with cardiopulmonary bypass (group On) in 17 cases and without cardiopulmonary bypass (group Off) in 19 patients [off-pump coronary artery bypass grafting (OPCAB) 15, minimally invasive direct coronary artery bypass (MIDCAB) 4]. There were no statistical differences regarding mean age, sex, duration of dialysis, preoperative hypertension, diabetes and peripheral and cerebral vascular diseases. Mean operation time and the number of bypass grafts were 315 +/- 53 minutes, 2.8 +/- 0.8 grafts in group On and 284 +/- 78 minutes, 2.4 +/- 1.1 grafts in group Off, respectively (not significant). Seventeen patients (100%) of group On and 12 patients (63%) needed blood transfusion. Hospital stay after operation was significantly longer in group On (40 days) of group Off than that in group Off (26 days). After the operation, continuous hemodiafiltration (CHDF) was used in 10 cases (59%) in group On and 3 cases (16%) in group Off. In coronary artery bypass grafting (CABG) on dialysis patient, it is very effective to have various operation techniques, such as off-pump bypass and on-pump beating bypass. Also control of water-electrolyte balance using early postoperative CHDF is useful. However, off-pump cases could be controlled by conventional hemodialysis.
