This study evaluates correlation in changes of HVPG-pressure values and stiffness values (ARFI) for spleen and liver and flow-volume values in Portal vein in patients with liver cirrhosis/Portal Hypertension, respectively, after new-admission of beta-blocker therapy.
Portal Hypertension is the most important risk factor for development of liver cirrhosis-linked complications (e.g. ascites, variceal bleeding, hepatocellular carcinoma, etc.). The invasive HVPG-technique is the standard-of-care Investigation for Evaluation of Portal Hypertension. Administration of Beta-Blocker-therapy results in dropping of the elevated Portal vein pressure values so Overall-survival rate and incidence of liver-cirrhosis-linked complications can be ameliorated. Ultrasound-based Investigation of liver and Spleen-stiffness and of portal-vein-flow-volume, respectively, are the non-invasive methods for Evaluation of Portal Hypertension. But the cut-off values for detection of significant Portal Hypertension by the ultrasound investigation strongly vary depending on the study performed. This study evaluates the changes in ARFI-assisted elastography measurements of liver and spleen and in portal vein flow values, respectively, compared with the recorded Delta in invasive hepatic vein pressure gradient (HVPG)-values for patients with portal hypertension and new administered beta-blocker-therapy. The aim of this study is to evaluate value drop in liver- and Spleen-stiffness and portal-vein-flow required in corelation to a significant drop in HVPG-pressure after new-administered beta-blocker therapy.
