ABSTRACT
O rthotopic liver transplantation (OLT) is a widely accepted treatment for end-stage chronic liver disease and severe liver failure. Despite improvement in survival due to advances in surgical technique, organ preservation technology and immunosuppressive strate gies, there are significant complications after liver transplantation. They include vascular, arterial and venous and biliary complications, infections, liver abscesses, fluid collections, haematomas, recurrent tumors, lymphoproliferative disorders. Vascular complications, such as arterial stenosis and venous trombosis are associated with a higher risk of graft disfunction and biliary complica tions remain a significant cause of morbidity and mortality after OLT. Early detection of these complications and adequate treatment is crucial in order to prevent loss of graft and improves graft and patient survival.
