Brief Summary

In patients with liver cirrhosis elevated levels of von Willebrand factor antigen (vWF-Ag) are found frequently but the clinical significance is unclear. vWF-Ag plays an important role in primary haemostasis and development of thrombotic vascular obliteration is discussed as a possible mechanism leading to portal hypertension. Invasive measurement of hepatic venous pressure gradient (HVPG) is the current gold standard for the diagnosis of portal hypertension. The investigators hypothesize that vWF-Ag levels in plasma may correlate with portal pressure and predict clinically significant portal hypertension (CSPH, HVPG \>=10mmHg) and its complications.

Outcome Measures

Primary Outcomes (1)

  • von Willebrand Factor Ag Level

    von Willebrand Factor Antigen Levels are measured via ELISA and compared /corrlated to Hepatic Venous Pressure Gradient (HVPG). von Willebrand Factor Antigen levels are drawn and analyzed at the day of HVPG measurement. No follow up measurements will be performed, survival will be measured as secondary outcome parameter

    at first visit (HVPG Measurement) (day 1)

Secondary Outcomes (1)

  • Overall Mortality

    3 Months

Eligibility Criteria

Study Population

Patients with liver cirrhosis of all etioloiges, routinely scheduled for routine HVPG measurement will systematically be included during the study period

You may qualify if:
