Chun, Ha, Choi, Kwon, Kim, Hwang, Ryeom, and Han: Late Hepatic Venous Outflow Obstruction Following Inferior Vena Cava Stenting in Patient with Deceased Donor Liver Transplantation Using Modified Piggyback Technique

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.

(A) The cranial end of the transjugular intrahepatic portosystemic shunt (TIPS) stent was located just below the right atrium, across the suprahepatic vena cava (arrow). (B) The caudal end of TIPS stent was placed at the junction of the inferior mesenteric and splenic veins (arrow).

This contrast-enhanced abdominal computed tomography (CT) scan shows a collapsed inferior vena cava (IVC) chamber on the donor side, a large amount of ascites fluid and liver graft congestion. (A) In comparison with the previous CT scan, the donor side IVC chamber had collapsed from extrinsic compression of the Palmaz stent (arrow). (B) A mottled pattern of contrast enhancement was observed in the portal venous phase.
