Core Tip
Core tip: Per-rectal portal scintigraphy (PRPS) and liver angioscintigraphy (LAS) are reliable investigations of the liver hemodynamics in the Budd-Chiari syndrome (BCS). Diagnosis of the number, length and succession in time of hepatic vein obstructions allows identification of hemodynamic varieties and stages of the BCS. Our new PRPS parameters, liver transit time and right heart to liver time, are used to diagnose obstructed hepatic veins, areas missing venous outflow or portal inflow, open collaterals, reverse splenic vein flow and hemodynamic role of the caudate lobe. LAS is useful in the differential diagnosis with portal occlusions, highlighting arterial-venous shunts and reverse portal flow.
