Wedged hepatic venous pressure reflects portal venous pressure during vasoactive drug administration in nonalcoholic cirrhosis.
Hepatic venous catheterization is widely used to assess portal pressure. However, it remains unclear whether wedged hepatic venous pressure is a close indicator of portal venous pressure during vasoactive drug administration in nonalcoholic cirrhosis. To address this issue, we analyzed the data from our previous published studies. Forty patients with nonalcoholic cirrhosis (HBV infection in five, HCV infection in 28, and cryptogenic in seven) were available in this analysis. A vasoconstrictor (N = 14), vasodilator (N = 10), or combination (N = 16) was administered. The agreement of the changes between portal and wedged hepatic venous pressures during pharmacological manipulation was assessed by an intraclass correlation coefficient. The intraclass correlation coefficient in each subgroup was more than 0.60 (0.62 in vasoconstrictor group, 0.87 in vasodilator group, and 0.73 in combination group). When the analysis was performed according to the cause of liver disease, the values were 0.67 in HBV infection, 0.73 in HCV infection, and 0.74 in cryptogenic cirrhosis. These results suggest that wedged hepatic venous pressure reflects portal venous pressure during vasoactive drug administration in patients with nonalcoholic cirrhosis.
