Document Summary
An abnormal and direct connection between the afferent and efferent sides of the hepatic circulation. Arteriovenous- from hepatic artery to portal or hepatic vein. Increase in pressure within the portal circulation of the liver, leading to increased resistance to hepatopetal portal flow. Increased pressure on the portal inflow, before entering the liver. Increased pressure because the liver itself is abnormally stiff or pressurized. Increased pressure on the hepatic outflow, after exiting the liver. Blood clot within the lumen of the portal vasculature, either partially or completely obstructing hepatopetal flow. Stasis secondary to cirrhosis and portal hypertension. An interventionally created direct pathway between the portal and hepatic circulation. Stent connecting the portal vein to the hepatic vein. Typically right portal vein connected to right hepatic vein. Blood rerouted away from the liver, out through the stent, into the hepatic vein, and back to the heart. Direction of flow should be documented in:
