[Percutaneous thrombus aspiration and thrombolysis for the treatment of acute portal vein thrombosis in a 5-year-old child].

Early portal vein thrombosis is a frequent and severe complication following pediatric liver transplantation. The clinical presentation is characterized by signs and symptoms of portal hypertension such as ascites and digestive hemorrhage. Primary treatment consists of heparin therapy. In the case of persistent or progressive thrombosis or symptoms, surgical thrombectomy or retransplantation should be considered. However, surgical intervention is associated with significant morbidity and mortality. We report on successful minimally invasive percutaneous thrombus aspiration and thrombolysis for the treatment of acute portal vein thrombosis in a 5-year-old child post liver transplantation.
