门脉压力通常于禁食一晚后次晨静息条件下测定,其所得参数对肝硬化及门脉高压患者的血液动力学评估具有重要价值。但目前还不清楚该参数24 h内是否稳定不变以及基线静息时所测能否代表其他状态的门脉压力。本文就这一问题对酒精性肝硬化患者作了观察。 对象和方法:10例有食管静脉曲张的肝硬化患者(其中1例女性,6例有腹水史)作为血液动力学观察对象,门脉压力由肝静脉梯度压(HVPG)估算,肝静脉楔压(WHVP)和肝静
Portal pressure is usually measured overnight after a fasting overnight, and the resulting parameters are of great value for hemodynamic assessment in patients with cirrhosis and portal hypertension. However, it is unclear whether this parameter is stable within 24 h and whether the measured baseline pressure at rest represents portal pressure in other states. This article on this issue for patients with alcoholic cirrhosis was observed. PARTICIPANTS AND METHODS: Ten patients with cirrhosis of esophageal varices (one female and six with history of ascites) were included in the hemodynamic study. Portal pressure was estimated by hepatic venous gradient pressure (HVPG) and hepatic venous wedge pressure (WHVP) and hepatic static
