Abstract

Arterial complications are some of the feared complications of hepatic transplantation. This stems from the fact that while hepatocytes derive most of their blood supply from the portal vasculature, bile ducts get their supply from the hepatic artery. Arterial insufficiency overtime causes biliary ischemia, necrosis, and often hepatic graft failure. Once suspected clinically, a prompt imaging work-up is usually performed. After confirmation of suspected hepatic arterial injury or insufficiency, quick intervention is usually required. Knowledge of the common hepatic artery complications, their imaging diagnosis, and different treatment modalities is critical for any provider who treats these patients. This review covers the imaging diagnosis and types of vascular injuries, and analyzes the different treatment options.
