Adult Living Donor Liver Re-Transplant Following Late Pediatric Liver Transplant Failure: A Case Report

Patient: Male, 14 Final Diagnosis: Primary sclerosing cholangitis Symptoms: Abdominal and/or epigastric pain • jaundice Medication: — Clinical Procedure: Liver transplantation twice • splenic artery embolization Specialty: Transplantology OBJECTIVE: Unusual clinical course BACKGROUND: Re-transplant of a late failing living donor liver graft using another graft from another living donor is a rare occurrence and is associated with high mortality due to the complexity of the procedure. There are only a few such case series reported in the literature, mainly from South Asia and Japan, where living donor liver transplant is commonly performed, and there are no such reports from Western countries. CASE REPORT: This is a case of living donor liver re-transplant for a 28-year-old recipient whose graft failed 14 years after his primary living donor transplant for primary sclerosing cholangitis. The second transplant was a right-lobe graft obtained from a living donor. The presence of portal vein thrombosis in the setting of high Model for End-Stage Liver Disease (MELD) score added to the complexity of the case. The procedure was concluded successfully with an uneventful post-operative course. The patient was discharged 3 weeks after the procedure. One-year follow-up showed a normally functioning graft. CONCLUSIONS: Successfully re-transplanting a patient with a failing living donor liver graft from a living donor is possible if sufficient surgical expertise is available and the risk and benefit are carefully considered. This is especially important in countries where a cadaveric graft is difficult to obtain due to organ scarcity.
