ReviewLiver transplantation: indications, pretransplant evaluation, surgery, and posttransplant complications.
Liver transplantation is the therapeutic option of choice for acute and chronic end-stage liver disease. The indications and contraindications to liver transplantation have become established, as has the operative and postoperative management. This article provides a practical clinical approach to the evaluation and management of patients with acute and chronic liver failure, with particular emphasis on liver transplant recipient selection, clinical management, and complications. The goal is to provide helpful guidelines to caregivers involved in the multidisciplinary care of these complex patients.

Acute liver failure (ALF) is a dramatic, highly unpredictable clinical syndrome defined by the sudden onset of coagulopathy and encephalopathy. Acetaminophen overdose, the leading cause of ALF in the United States, has a 66% chance of recovery with early N-acetylcysteine treatment and supportive care. Cerebral edema and infectious complications are difficult to detect and treat in these patients and may cause irreversible brain damage and multiorgan failure. One-year survival after emergency liver transplantation is 70%, but 20% of listed patients die, highlighting the importance of early referral of patients who have ALF with a poor prognosis to a transplant center.
