case_images: Computed tomography (CT) abdominal scan showed thrombi in the middle and right intrahepatic veins and in the IVC involving bilateral renal and external iliac veins (Figure 1).
case_images: Axial post-contrast CT at the level of the liver demonstrating calcification
  around a narrowed non-enhancing intrahepatic IVC (black arrow) and
  ascites.

case_images: Moderate volume ascites was also present (Figure 2).
case_images: Coronal post-contrast CT abdominal scan post-stenting of the inferior vena

case_images: A Viatorr  (Gore, Flagstaff, AZ, USA) polytetrafluoroethylene (PTFE)-covered stent was deployed between the right portal vein and within the IVC stent with achievement of good flows through the TIPS stent into the right atrium and reduction in portosystemic gradient to 9 mmHg (Figure 4).
