Spectrum of CT findings in pediatric patients after partial liver transplantation

Liver transplantation is an accepted therapy for patients with severe liver diseases. In pediatric liver transplantation, the application of reduced-s ize and split-liver transplantation has expanded the donor pool. The develo pment of living related donor partial liver transplantation has further inc reased the availability of donors. Complications in patients after living r elated transplantation include hepatic arterial thrombosis, portal venous s tenosis and thrombosis, hepatic venous stenosis, biliary stenosis or leak, biloma formation, fatty liver, extrahepatic fluid collection, posttransplan tation lymphoproliferative disorder, and organ rejection. Ultrasonography i s the primary imaging modality for evaluation of the vascular system of pat ients after liver transplantation, and computed tomography is useful to hel p diagnose hepatic parenchymal abnormalities including infarction, congesti on, and fatty change; intrahepatic biliary damage; and extrahepatic disorde rs, including abnormal fluid collections, varicose veins, and lymphadenopat hy.
