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.
目的： 经颈静脉或经股动脉途径被用作当前实践中肝静脉压力梯度（HVPG）测量的常用方法。该研究旨在证实经前臂静脉途径测量HVPG的安全性和有效性。 方法： 针对2020年9月至2020年12月前瞻性地从中国和日本的6所医院招募了经前臂静脉进行HVPG检测肝硬化患者，并收集患者的临床基线资料以及HVPG检测数据。入组患者均选择经右侧肘正中静脉或贵要静脉入路，采用HVPG标准化流程进行测压。研究数据采用SPSS 22.0统计学软件进行分析。定量资料采用中位数（四分位数间距）表示，定性资料采用频数和率表示。两组数据之间的相关性分析采用Pearson相关性分析。 结果： 研究共入组43例患者，其中41例（95.3%）患者成功接受了经前臂静脉途径HVPG检测。无患者出现任何严重并发症。经前臂静脉途径HVPG检测中位操作时间为18.0min（12.3～38.8min）。研究证实HVPG与Child-Pugh评分（r = 0.47，P = 0.002）、白蛋白-胆红素评分（r = 0.37，P = 0.001）、Lok指数（r = 0.36，P = 0.02)、肝脏硬度(r = 0.58，P = 0.01)、脾硬度(r = 0.77, P = 0.01)呈正相关，且与白蛋白呈负相关(r = -0.42, P = 0.006)。 结论： 多中心回顾性研究结果提示经前臂静脉途径HVPG测量是安全可行的。.
