WebBackground: Hepatic portal venous gas (HPVG) is a pathological condition characterized by gas in the portal venous system and its branches. The clinical manifestations of HPVG range from benign to life-threatening conditions. Here, we present a rare case of HPVG accompanied by free air in a healthy young patient without any suspicious etiology. Webcatheter does not occlude the hepatic vein, the free pressure (FHVP) is obtained. Measurement of Portal Venous Pressure. Portal venous pressure was measured by either percutaneous puncture under ultrasonographic and radiological guidance (n 5 25) or by a transjugular approach during the placement of a transjugular intrahepatic portosystemic
