title: Portal Vein Thrombosis and Arterioportal Shunting Due To Chronic Cholangitis: A Rare Complication of Living-Donor Liver Transplant.
abstract: OBJECTIVE
  We present a patient with portal vein thrombosis due to chronic cholangitis after undergoing a living-donor liver transplant.
  
  
  METHODS
  A 52-year-old woman with a history of hepatitis B virus-related liver cirrhosis underwent a living-donor liver transplant. After the surgery, the patient had recurrent episodes of cholangitis because of common and intrahepatic bile duct stricture. Biliary stricture because of cholangitis eventually resulted in acute portal vein thrombosis. A stent was inserted by percutaneous transluminal portography. Blood flow through the portal vein progressively improved from the third through the 10th day after stent placement. The anticoagulation regimen was change to acetylsalicylic acid and clopidogrel hydrogen sulfate (Plavix). On poststenting day 10, a follow-up computed tomographic scan showed good patency of the main portal vein and no evidence of arterioportal shunting.
  
  
  CONCLUSIONS
  Cholangitis after living-donor liver transplant is a rare cause of portal vein thrombosis. Regular follow-up examinations with color Doppler ultrasound are required to monitor portal vein flow in patients with biliary complications after living-donor liver transplant.
