Abstract
The hepatic venous pressure gradient (HVPG), which is the difference between the wedged (WHVP) and free hepatic vein pressures (FHVP), is the gold standard to evaluate portal hypertension in patients with cirrhosis 1 Bosch J Abraldes JG Berzigotti A et al. The clinical use of HVPG measurements in chronic liver disease. Nat Rev Gastroenterol Hepatol. 2009; 6: 573-582 Crossref PubMed Scopus (436) Google Scholar . Unfortunately, there currently exists a gap in the evaluation of patients with pre-sinusoidal portal hypertension, where HVPG is known to underestimate portal pressure. Endoscopic ultrasound-guided portal pressure gradient measurement (EUS-PPG) has recently brought back the possibility of safely obtaining direct portal vein pressure (PVP) and represents a long-awaited less-invasive diagnostic tool for patients with suspected pre-sinusoidal portal hypertension.
