Vascular anomalies associated with hepatic shunting

Table 2 Park’s classification of congenital intrahepatic portosystemic shunts

Park’s classification of congenital intrahepatic portosystemic shunts[5]
Large connection of constant diameter from the right portal vein to the intrahepatic IVC
Localized peripheral shunt from multiple or single communications between the peripheral branches of the portal and hepatic veins within one hepatic segment
An aneurism between connecting peripheral portal and hepatic veins
Multiple communications between peripheral and hepatic veins peripherally throughout the liver
Patent ductus venosus

IVC: Inferior vena cava.
