Spleen-ARFI-assisted-Portal-Hypertension-Evaluation-Study (SAPHES)
Study Details
Study Description
Brief Summary
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.

Detailed Description
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.

---|---|
Other: cirrhosis patients ARFI-elastography and portal vein flow measurement: Liver and spleen of patients with a scheduled HVPG-investigation will be examined by an ARFI-elastography-investigation. Additionally the portal vein flow will be assessed. This examination will be done at d0 before the start of beta-blocker-administration and repeated as monitoring for portal hypertension treated by beta-blocker after 6 and 12 weeks, respectively. HVPG-measurement: HVPG-values will be assessed at d0, after 6 and after 12 Weeks, respectively. |
