Individual values for portal pressure gradient (PPG) in patients with moderate and severe transjugular intrahepatic portosystemic shunt (TIPS) dysfunction. The number of patients with a decreasing PPG to below 12 mm Hg was significantly greater among those with moderate dysfunction than in those with severe TIPS dysfunction (8/10 v 1/8; p=0.015). This was due to the lower baseline PPG of patients with moderate dysfunction as the absolute fall in PPG was similar in both groups.
