Liver transplantation for acute hepatic failure.

ABSTRACT

INTRODUCTION: The mortality rate of acute hepatic failure (AHF) with conservative treatment is 40% to 90%, depending on the etiology. Hepatitis B infection is the major cause of AHF in Asia. In this study, we examined the role of liver transplantation for adult patients with AHF. METHODS: Sixteen patients with AHF received liver transplants in the past 6 years. Eight patients received cadaveric donor and another 8 living-related donor grafts. Fifteen patients suffered from hepatitis B-related disease and 1 had drug-induced AHF. Extracorporeal charcoal hemoperfusion was used as a bridge to liver transplantation in the first 2 patients and plasma exchange was used in the following patients. RESULTS: One patient died 1 month after the operation due to primary nonfunction. The other 15 patients are alive with good graft function at 2 months to 6 years follow-up. The success rate is 94%. Postoperative complications included infection in 10 patients (62.5%), acute rejection in 4 patients (25%), and biliary complication in 2 patients (12.5%). No neurological complications were noted. CONCLUSION: Liver transplantation is the most effective treatment for patients with AHF. Living donors may be considered due to the organ shortage and the critical patient disease.
