Fig. 3. Percutaneous transhepatic hepatic venous stenting. (A) A right inferior hepatic venography obtained via the percutaneous transhepatic approach, showing total occlusion at the anastomosis between the right inferior hepatic vein (RIHV) and the inferior vena cava (IVC) (arrow). (B) A right inferior hepatic venography after stent placement showing restorationof RIHV flow. The pressure gradient between the RIHV and the right atrium (RA) was 2 mmHg. (C) A right hepatic venogram obtained via the percutaneous transhepatic approach showing occlusion at the anastomosis between the right hepatic vein (RHV) and the IVC (arrow). The RHV was drained to the RIHV via the capsular vein of the liver (arrowheads). (D) RHV stent placement was performed, and pressure gradient between the RHV and the RA was 6 mmHg. Thus, additional balloon dilatation was performed for stent expansion. The final right hepatic venography after stent placement and balloon dilatation, showing good flow to the IVC. The final pressure gradient between the RHV and the RA was 2 mmHg.
