Imaging in liver transplantation

Imaging in liver transplantation is aimed to evaluate donor and recipient for successful transplantation and its outcome.

Pre-transplant evaluation

Donor
  • volume of liver
  • parenchymal disease (diffuse or focal)
  • vascular anatomy
    • arterial variations 
    • venous variations
  • biliary anatomy
Recipient

Post-transplant evaluation

Normal findings in recipient
  • perihepatic hematoma
  • right-sided pleural effusion
  • minimal ascites
  • periportal edema
Complications 
  • rejection (can be diagnosed accurately with biopsy only)
  • related to vascular anastomosis
    • hepatic arterial thrombosis
      • may result in small abscesses in transplanted liver
    • arterial pseudoaneurysm
    • portal vein thrombosis / stenosis
    • hepatic vein thrombosis
    • IVC thrombosis
  • related to biliary anastomosis
    • bile leaks
    • biliary obstruction
      • anastomotic / non-anastomotic (infection, ischemia) strictures
      • calculus formation
      • cholangitis
  • sepsis
  • recurrent disease
  • posttransplantation lymphoproliferative disease
