title: Percutaneous mechanical fragmentation and stent placement for the treatment of early posttransplantation portal vein thrombosis.
abstract: BACKGROUND
  Early portal vein thrombosis is a rare but severe complication of liver transplantation requiring retransplantation or at least surgical thrombectomy, both hampered by high morbidity and mortality.
  
  
  METHODS
  We describe of a case of successful long-term recanalization of early posttransplantation portal vein thrombosis by a minimally invasive percutaneous transhepatic angiographic approach using both mechanical fragmentation and pharmacological lysis of the thrombus followed by stent placement.
  
  
  RESULTS
  Mechanical fragmentation and contemporaneous local urokinase administration resulted in complete removal of the clot; the use of a vascular stent after balloon dilatation allowed restoration of normal blood flow to the liver after 9 months of follow-up.
  
  
  CONCLUSIONS
  This case report confirms the possibility of successful recanalization of the portal vein after early posttransplantation thrombosis by a minimally invasive angiographic approach. Balloon dilatation and placement of a vascular stent could help to decrease the risk of recurrent thrombosis.
