1) The attendees will know the various types of percutaneous portal procedures performed. 2) The attendees will understand the hemodynamic definitions & concepts of inflow and outflow. 3) The attendees will understand that increasing antegrade portal venous does not necessarily increase the functional inline portal venous flow to the liver hepatocytes. 4) The attendees will understand what procedures are categorized as procedures that would increase or decrease inline portal venous inflow. 5) The attendees will understand the correlations between nominal portal pressures, pressure gradients and portal flow (velocity, volume and direction).

Abstract: Portal interventions include: Transjugular Intra hepatic PortoSystemic Shunts (TIPS), portal vein angioplasty / Stenting, Balloon-occluded retrograde Transvenous obliteration (BRTO), hepatic venous interventions for Budd-Chiari, para umbilical vein occlusion and extrahepatic PortoSystemic shunt occlusion. The lecture will discuss the effects of these procedures on nominal portal pressures, pressure gradients and portal flow (velocity, volume and direction) and inline portal blood flow to the functional liver (hepatocytes).
