A 64-year-old patient with chronic renal failure underwent coronary artery bypass grafting (CABG) because of the frequent severe angina during hemodialysis. Intraoperative hemodialysis and extra-corporeal ultrafiltration method (ECUM) was used during cardiopulmonary bypass. Postoperative management was successfully performed by continuous ambulatory peritoneal dialysis (CAPD), which made hemodynamics stable and prevented postoperative bleeding, providing with adequate fluid removal and satisfactory control of serum chemistry.
