Mentions: The catheter should be advanced along the main RHV, which will be oriented along the axis of the ribs. If the RHV cannot be cannulated, the middle or left hepatic veins can be tried. A hepatic venogram is performed by injecting 5 - 10 ml of contrast [Figure 2]. The venogram is essential to confirm that the catheter is in the hepatic vein. Rarely, the right renal vein can be mistaken for the RHV.
