Transient elastography accurately predicts presence of significant portal hypertension in patients with chronic liver disease.

Abstract : BACKGROUND: Hepatic venous pressure gradient (HVPG) is a prognostic marker in patients with cirrhosis. Transient elastography measures liver stiffness (LS). AIM: To assess the correlation between LS and HVPG and to investigate the performance of transient elastography for the diagnosis of significant portal hypertension (PHT). METHODS: Liver stiffness was measured by Fibroscan in 150 consecutive patients who underwent a liver biopsy with haemodynamic measurements. Usual clinical and biological data were collected. Significant PHT was defined as a HVPG > or = 10 mmHg. RESULTS: Hepatic venous pressure gradient was found to be > or = 10 mmHg in 76 patients. Cirrhosis was diagnosed in 89 patients. HVPG was found to be correlated with: LS (rho = 0.858; P < 0.001) and inversely correlated with prothrombin index (rho = -0.718; P < 0.001). Regarding significant PHT, AUROC for LS and prothrombin index were 0.945 [0.904-0.987] and 0.892 [0.837-0.947] respectively. The cut-off value of 21 kPa accurately predicted significant PHT in 92% of the 144 patients for whom LS was successful. CONCLUSION: Liver stiffness measurement is correlated with HVPG and transient elastography identifies patients with significant PHT.
