Abdominal CT following liver transplantation

Computed tomography (CT) is one of several imaging modalities employed in the evaluation of complications following orthotopic liver transplantation. Abdominal CT scans were performed in 92 (48%) of the first 190 liver transplant patients at our institution. These studies were retrospectively reviewed to determine the indications for CT in this population and to determine the incidences of the various CT findings. The major indication (70%) was detection of bile leakage, hemorrhage, or abscess. The role of CT was primarily to discover such abnormal fluid collections and guide their percutaneous drainage. This article describes a wide spectrum of common and uncommon findings following liver transplantation and illustrates their CT features.
