EUS-guided portal venous pressure versus portal pressure gradient for detecting esophageal varices in a single-center observational cohort
EUS-guided portal hemodynamic assessment has focused on the portal pressure gradient (PPG). In an endoscopic setting, the downstream hepatic component used to compute the gradient may introduce additional variability in the measurement. To compare EUS-measured absolute portal venous pressure (PVP) and PPG for clini...
