title: Percutaneous Transhepatic Angioplasty for Portal Vein Cavernous Transformation after Choledochal Cyst Surgery.
abstract: BACKGROUND
  Cavernous transformation of the portal vein rarely occurs after a choledochal cyst surgery.
  
  
  METHODS
  A 7-year-old boy with a history of a choledochal cyst surgery was admitted with recurrent oral and nasal bleeding over next two years. After excluding coagulopathies and hematopathies, we treated him with percutaneous transhepatic angioplasty.
  
  
  RESULTS
  The flow of the portal vein recovered immediately after balloon dilation. The patient's symptoms were relieved, and no recurrence or complications occurred.
  
  
  CONCLUSIONS
  Stenosis and cavernous transformation of portal vein can be successfully managed by percutaneous transhepatic angioplasty.
