Relationship between directly measured portal pressure gradient and variceal hemorrhage.
It is commonly believed that variceal hemorrhage in patients with cirrhosis and portal hypertension does not occur below a portal pressure gradient (PPG) of 12 mm Hg. The aim of this study was to assess the relationship between directly measured portal pressure gradient and variceal hemorrhage. ⋯ The results of this study do not support the concept of a discrete bleeding threshold.
