WebThe Normal Range of Wedge Pressure. The nor- mal range of wedge pressure reported in the literature is from 0 to 11.2 mm. Hg above the right atrium [1,3-5]. Our own results in a limited number of "normal" patients suggest that wedge pressure is probably seldom more than 5 to 6 mm. Hg higher than vena caval pressures. 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.
