Objective The transjugular or transfemoral approach is used as a common method for hepatic venous pressure gradient(HVPG)measurement in current practice.This study aims to confirm the safety and effectiveness of measuring HVPG via the forearm venous approach.Methods Prospective recruitment was conducted for patients with cirrhosis who underwent HVPG measurement via the forearm venous approach at six hospitals in China and Japan from September 2020 to December 2020.Patients'clinical baseline information and HVPG measurement data were collected.The right median cubital vein or basilic vein approach for all enrolled patients was selected.The HVPG standard process was used to measure pressure.Research data were analyzed using SPSS 22.0 statistical software.Quantitative data were used to represent medians(interquartile ranges),while qualitative data were used to represent frequency and rates.The correlation between two sets of data was analyzed using Pearson correlation analysis.Results A total of 43 cases were enrolled in this study.Of these,41(95.3％)successfully underwent HVPG measurement via the forearm venous approach.None of the patients had any serious complications.The median operation time for HVPG detection via forearm vein was 18.0 minutes(12.3～38.8 minutes).This study confirmed that HVPG was positively closely related to Child-Pugh score(r=0.47,P=0.002),albumin-bilirubin score(r=0.37,P=0.001),Lok index(r=0.36,P=0.02),liver stiffness(r=0.58,P=0.01),and spleen stiffness(r=0.77,P=0.01),while negatively correlated with albumin(r=-0.42,P=0.006).Conclusion The results of this multi-centre retrospective study suggest that HVPG measurement via the forearm venous approach is safe and feasible.
