Living donor liver transplantation (LDLT) is a treatment for end-stage liver failure, and was developed to overcome the distinct insufficiency of cadaveric donors. Case 1 is a 56-year-old man who had undergone maintenance hemodialysis therapy for 4 years. An LDLT was performed for the treatment of advanced liver cirrhosis and hepatocellular carcinoma. Continuous hemodiafiltration (CHDF) was performed from the 2nd to 5th days after the operation. Case 2 is a 55-year-old man with primary amyloidosis and chronic renal failure. An LDLT was performed for the treatment of severe abdominal distention caused by a large liver volume. Although CHDF was started at the 3rd day after the operation, it was discontinued within 24 hours because of an increased urinary volume. CHDF was required again from the 6th-8th days, after which the blood purification mode was switched to regular intermittent hemodialysis. Meanwhile, no major problems occurred in either case. In conclusion, CHDF was required for about 5 days from the 2nd day after the operation. The application of careful and aggressive blood purification therapy during the perioperative period is a key to successful LDLT in dialysis patients.
