A Case of Hepatic Artery Thrombosis after Liver Transplantation

Introduction: Hepatic artery thrombosis (HAT) is the most serious vascular complication after liver transplantation. The most common presentation is elevation of liver function tests. When the diagnosis of hepatic arterial thrombosis is established, prompt intervention should be performed.
Case Presentation: In this case report, we present a 37-year-old male with Chronic Hepatitis B infection who underwent a successful liver transplantation, and later developed multiple complications. The most significant of which is hepatic artery thrombosis. He underwent revascularization, supported by heparin and prostaglandin infusion. Succeeding doppler ultrasound surveillance showed patency of right hepatic artery flow. 
Conclusion: Early identification of hepatic artery thrombosis should be paid attention after liver transplantation to prevent its complications. Once the diagnosis is established, prompt intervention such as retransplantation or revascularization should be performed.
