Abstract

Non-occlusive hepatic artery hypoperfusion syndrome (NHAHS), in other words, splenic steal, is a rare disorder that can arise following liver transplantation. After liver transplantation, its frequency has been defined as between 0.6 and 10.1%. The diversion of flow from hepatic to splenic arteries results in low perfused hepatic artery which causes elevated liver enzymes, hyperbilirubinemia, and graft dysfunction. This may result from a high resistance in the hepatic arteries, enlarged splenic arteries, a limited hepatic arterial flow due to high portal flow, or a discordance of the graft size and hepatic arterial flow. There may be a need for some prophylactic and/or posttransplant treatment procedures. We aimed to describe pre and post-treatment imaging findings of NHAHS.

Keywords: Liver transplantation; Nonocclusive hepatic artery hypoperfusion syndrome; Splenic steal.
