The Efficacy of Continuous Hemodiafiltration (CHDF) in the Management of Two Cases or Chronic Renal Failure in the Early Postoperative Period Following Cardiovascular Surgery / 日本心臓血管外科学会雑誌

ABSTRACT

The early postoperative use of continuous hemodiafiltration (CHDF) was effective in the postoperative management of two patients with chronic renal failure (CRF) undergoing cardiovascular operation. The first case was a 74-year-old man with a ruptured abdominal aortic aneurysm who underwent emergency Y-shaped artificial graft replacement. The second case was a 55-year-old man with aortic valve stenosis and regurgitation who underwent aortic valve replacement with a mechanical cardiac valve. Both patients had had chronic renal failure for several years before the operation, and the second patient had been on intermittent hemodialysis. Although a large amount of blood transfusion was needed postoperatively in both cases, CHDF enabled us to maintain the electrolytes in the normal range and control the water balance. The influence on the hemodynamics was minimized by adjusting the filtration rate. In conclusion, CHDF is useful for the management of CRF in the early postoperative period following cardiovascular surgery.
