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.
