Late Hepatic Venous Outflow Obstruction Following Inferior Vena Cava Stenting in Patient with Deceased Donor Liver Transplantation Using Modified Piggyback Technique / 대한이식학회지

ABSTRACT

Following liver transplantation, a few reports have documented hepatic venous outflow obstruction (HVOO) after inferior vena cava (IVC) stenting for the treatment of IVC stenosis. However, HVOO occurred early after IVC stenting and was mostly associated with living donor liver transplantation. Here, we report a case of HVOO that occurred 31 months after IVC stenting in a man who received deceased donor liver transplantation (DDLT) using a modified piggyback (PB) technique. The cause of HVOO was unclear, but one possible explanation is that the balloon-expandable IVC stent might have compressed the IVC chamber on the donor liver side, which would have changed the outflow hemodynamics, resulting in intimal hyperplasia. Therefore, simultaneous hepatic venous stenting with IVC stent placement could help prevent HVOO in patients receiving DDLT with the modified PB technique.
