Figure 2: Power injection in anteroposterior (left) and lateral (right) projections within the inferior vena cava limb of the Fontan pathway. Note the dextrocardia and mid-line liver. (a) The normally connecting hepatic veins (*) backfill early after contrast injection into the inferior vena cava. (b) A complex meshwork of interlobar hepatic collaterals (#) connects the inferior vena cava-hepatics to an anomalous hepatic that drains directly into the atrium (†). No contrast is seen within the inferior vena cava stent since all inferior vena cava flow is directed right-to-left into the atrium via the hepatic venous connections. Also seen is the vascular plug device in a previously occluded anomalous atrial-draining hepatic vein
