Abstract:
Objective To evaluate the efficacy of liver transplantation for acute liver failure (ALF) in children. Methods Clinical data of 15 children with ALF who underwent liver transplantation were collected and retrospectively analyzed. The proportion of ALF among children undergoing liver transplantation during the same period was calculated. The characteristics, postoperative complications and clinical prognosis of ALF children receiving liver transplantation were analyzed. Results In the same period, the proportion of ALF was 2.0% (15/743) among pediatric recipients undergoing liver transplantation. All 15 children had acute onset of ALF, and most of them were accompanied by fever, diarrhea and progressive yellowing of skin and sclera. Thirteen children were complicated with hepatic encephalopathy before operation (6 cases of stage Ⅳ hepatic encephalopathy), and two children were complicated with myelosuppression and granulocytopenia before liver transplantation. Ten children underwent living donor liver transplantation with relative donor liver, 4 received liver transplantation from donation after cardiac death (DCD), and 1 underwent Domino donor-auxiliary liver transplantation. Of 15 children, 12 recipients had the same blood type with their donors, 1 recipient had compatible blood type with the donor and 2 cases had different blood type with their donors. Among 15 children, 10 cases developed postoperative complications. Postoperative cerebral edema occurred in 5 cases, of whom 4 cases died of diffuse cerebral edema, and the remaining case was in a persistent vegetative state (eyes-open coma). Postoperative cytomegalovirus (CMV) infection was seen in 5 cases. Two children presented with aplastic anemia and survived after bone marrow transplantation, 1 case died of CMV hepatitis and viral encephalitis, and 2 cases died of diffuse brain edema. One child developed graft-versus-host disease (GVHD) after liver transplantation, and died of septic shock after bone marrow transplantation. Nine children survived and obtained favorable liver function during postoperative follow-up. Conclusions Liver transplantation is an efficacious treatment for ALF in children, which may enhance the survival rate. Brain edema is the main cause of death in ALF children following liver transplantation, and treatment such as lowering intracranial pressure, improving brain metabolism and blood purification should be actively performed. Liver transplantation should be promptly performed prior to the incidence of irreversible neurological damage in ALF children, which might prolong the survival and enhance long-term prognosis.
