Living related liver transplantation for acute liver failure in children.
The mortality rate among children with acute liver failure (ALF) on the waiting list for liver transplantation is high. We present our experience with living related donor liver transplantation (LRD-LT) in children who required urgent transplantation for ALF. Between December 1995 and July 1997, 6 children underwent LRD-LT for ALF. Cause of liver failure, recipient and donor demographics, clinical and laboratory data, surgical details, complications, and 6-month and 2-year graft and patient survival were recorded. Five boys and 1 girl received left lateral segment grafts from their parents. The mean age was 4 +/- 2.8 years (range, 1 to 9 years). ALF was caused by Wilson's disease in 1 patient and sickle cell intrahepatic cholestasis syndrome in 1 patient; in 4 patients, the cause was unknown. All patients had mental status changes; 2 were on life support. Mean pretransplantation liver function test values were: alanine aminotransferase, 972 +/- 565 U/L (normal, 1 to 53 U/L), total bilirubin, 31.3 +/- 12.4 mg/dL (normal, 0.1 to 1.2 mg/dL), prothrombin time, 34.3 +/- 12.4 seconds (normal, 10.8 to 13.3 seconds), international normalized ratio, 8.46 +/- 5.4 (normal < 2), and fibrinogen, 109 +/- 23.9 mg/dL (normal, 175 to 400 mg/dL). The donors were 5 mothers and 1 father. The mean donor age was 32.5 +/- 7.6 years (range, 19 to 40 years). No donor required blood transfusion, and no donor had any early or late postoperative complications. The donors' mean hospital length of stay was 5 days. In five cases, grafts were blood group-compatible; 1 child received a blood group-incompatible graft. All grafts functioned immediately. No patient had hepatic artery or portal vein thrombosis or biliary complications. The child who received a mismatched graft died of infection of the brain caused by Aspergillus spp at 22 days posttransplantation with a functioning graft. The child with ALF caused by sickle cell intrahepatic cholestasis syndrome developed outflow obstruction 3 months posttransplantation and required retransplantation; he eventually died of vascular complications related to his primary disease. Four children are alive at a mean follow-up of 27 months (range, 14 to 36 months). LRD-LT for children with ALF facilitates timely transplantation without drawing on cadaveric donor resources. The established safety record of LRD-LT made this option appealing to both physicians and parental donors.
