COMPARISON OF WEDGED HEPATIC VEIN PRESSURE WITH PORTAL VEIN PRESSURE IN HUMAN SUBJECTS WITH CIRRHOSIS 12

Abstract
Portal vein pressure (PVP) and the pressure measured from a catheter wedged into a peripheral hepatic venule (WHVP) were compared in 19 cirrhotic patients undergoing abdominal surgery. WHVP correlated reasonably well with PVP in all instances. In 10 simultaneous comparisons WHVP averaged 20% (range 9-28%) below PVP. In 5 patients WHVP averaged 15% (range 13-23%) lower at surgery than preoperatively. WHVP has proven to be a useful clinical measurement.
