Zusammenfassung

Die Lebervenenverschlussdruckmessung stellt ein indirektes Verfahren zur Bestimmung des Druckes in der V. portae dar. Sie basiert auf der Prämisse, dass der Lebervenenverschlussdruck (LVVD oder „wedged hepatic venous pressure“, WHVP) dem pfortaderdruck entspricht bzw. eng mit diesem korreliert. Der Messung liegt das Prinzip der kommunizierenden Röhren zugrunde. Wird ein Katheter so tief in einen Lebervenenast eingeführt, dass die Katheterspitze die Vene verschließt („Wedgeposition“, Lebervenenverschluss), entspricht der über den Katheter gemessene Druck demjenigen am nächsten Punkt der freien Kommunikation mit der hepatischen Zirkulation. Damit ist der Lebervenenverschlussdruck letztlich ein Maß für den Druck in dem dem Katheter „vorgeschalteten“ sinusoidalen und postsinusoidalen Gefäßbett.
