ABSTRACT
ObjectiveTo investigate the diagnosis and treatment of hepatic venous outflow obstruction(HVOO) after pediatric liver transplantation.MethodsFrom Jan.2000 to Dec.2009,48 children received liver transplantation in the Department of Liver Transplantation,First Central Hospital,Tianjin.There were 3 patients who developed HVOO (2 received liver transplantation in our center,while the third from another centre).The HVOO was diagnosed by color Doppler ultrasound (CDUS),computed tomography (CT),and angiography of inferior vena cava (IVC).The patients received balloon dilation and/or stent placement and followed-up with regular monitoring.ResultsIn our center,the incidence rate of HVOO was 4.17% (2/48).The time of onset was 2 months to 1 year postoperatively.The pressure gradient between the hepatic vein and the right atrium was from 6 to 30mmHg.After treatment,the venous pressure gradient decreased from 4 to 10mmHg.Resolution of clinical symptoms was achieved in these patients.HVOO relapsed in two patients who received balloon angioplasty only.The clinical symptoms were relieved after repeated balloon dilation in one and stent placement in the other.There were no further complications after these procedures.All patients were alive at a follow-up from 2 months to 9 years.ConclusionThe incidence of HVOO after pediatric liver transplantation was not high,but HVOO led to serious consequences.Balloon dilation and/or stent implantation were safe and efficacious treatments for HVOO after pediatric liver transplantation.
