Portale Hypertension

Chapter

Zusammenfassung

Der normale Druck in der Pfortader liegt zwischen 3 und 6 mm Hg. Die portale Hypertension ist als dauerhafte Erhöhung des Pfortaderdrucks auf Werte ≥ 7 mm Hg und/oder des transhepatischen Druckgradienten zwischen geblocktem Lebervenenverschlussdruck und dem Druck im zentralen Venensystem des systemischen Kreislaufs auf Werte ≥ 5 mm Hg definiert. Die Erhöhung des portalvenösen Gradienten auf Werte < 10 – 12 mm Hg, Varizen, Varizenblutung und/oder Aszites zeigen die klinisch signifikante portale Hypertension an.
