Blocking of the hepatic vein outflow by neointima covering a wallstent across a membranous stenosis of the inferior vena cava.
A 31-year-old man presented with idiopathic membranous obstruction of the suprahepatic inferior vena cava (IVC) and was treated by balloon dilation and placement of a Wallstent. The patient improved markedly. However, he developed obstruction of the hepatic vein outflow secondary to neointima formation over the stent that covered the hepatic vein ostia. The patient died of liver failure and septicemia. We believe that this is the first report of such a serious complication.
