    Abstract:
    Plasma diafiltration (PDF) is a blood purification therapy in which simple plasma exchange (PE) is performed using a selective membrane plasma separator while the dialysate flows outside of the hollow fibers. A prospective, multicenter study was undertaken to evaluate the changes in biochemical examination of blood and the 28-day and 90-day survival rates of patients with postoperative liver failure (PLF). Eleven patients with PLF were studied with the therapy performed 98 times. The Model for End-Stage Liver Disease (MELD) score was categorized into three grades: 20-29, 30-39, and 40 or higher. The survival rate was assessed by the severity of MELD score. The 28-day survival rate was 45.5% and that at 90 days was 27.3%. The levels of total bilirubin, BUN, and creatinine decreased significantly after treatment. On the other hand, the levels of total protein increased after treatment and those of albumin did not change significantly. PDF may be the useful blood purification therapies for use in cases of PLF in terms of medical economics and the removal of water-soluble and albumin-bound toxins.
