  • Title: Hepatic venous pressure gradient supplements liver biopsy in the diagnosis of cirrhosis.
    Author: Wolf AT, Maurer R, Glickman J, Grace ND.
    Journal: J Clin Gastroenterol; 2008 Feb; 42(2):199-203. PubMed ID: 18209592.
    Abstract:
    BACKGROUND: Liver biopsy is the gold standard for establishing cirrhosis, but may provide inadequate tissue for interpretation in some patients. GOALS: The aim of this study was to determine whether the hepatic venous pressure gradient predicts the presence of cirrhosis. STUDY: Patients with liver disease who had undergone hepatic venous pressure gradient measurements were identified. Clinical, laboratory, and hepatic venous pressure gradient data were collected and biopsies were staged for fibrosis. Univariable logistic regression was used to identify potential predictors of cirrhosis. Multivariable logistic regression was applied to determine adjusted odds ratios. RESULTS: Thirty-two patients were included. The hepatic venous pressure gradient was an independent predictor of cirrhosis. On multivariable analysis, the hepatic venous pressure gradient predicted cirrhosis, with an odds ratio of 1.46 (95% confidence interval 1.05-2.02, P=0.023). Using a cutoff of >or=6.5 mm Hg, the hepatic venous pressure gradient was 86% sensitive and 80% specific for diagnosing cirrhosis. CONCLUSIONS: The hepatic venous pressure gradient measurement predicts the presence of cirrhosis in patients with liver disease. Therefore, when the diagnosis of cirrhosis is in question, an elevated hepatic venous pressure gradient can support the diagnosis.
