Concurrent Inferior Vena Cava and Hepatic Vein Stenoses After Orthotopic Liver Transplantation: A Case Report

Abstract

Outflow obstruction or stenosis of a hepatic graft is a rare but serious complication after liver transplantation, with a reported incidence of 1% to 6%. It can cause signs of portal hypertension, renal dysfunction, or lower-extremity edema depending on the level of obstruction, which may lead to patient mortality. Most reported cases show a stenosis at either the inferior vena cava (IVC) or one of the hepatic veins. Herein we have reported our experience of concurrent suprahepatic IVC and hepatic vein stenoses after orthotopic liver transplantation with related imaging findings and a successful treatment outcome. Due to the complexity of stenoses, two self-expandable metallic stents were placed simultaneously using different venous accesses.
