Zusammenfassung
Varizen im Ligamentum hepatoduodenale und in der Leberpforte sind normalerweise Folge
einer kavernösen Transformation einer verschlossenen Portalvene. Wir stellen den ungewöhnlichen
Fall einer asymptomatischen 86-jährigen Patientin mit Varizen des Ductus coledochus
vor, welche wegen Verdachts auf ein Cholangiokarzinom an unserer Klinik abgeklärt
wurde. Die Diagnose konnte schließlich mit transabdominalem Doppler-Ultraschall gestellt
werden. Dieser zeigte multiple erweiterte Gefäße in der Gallengangswand. Die meisten
Patienten mit Gallengangsvarizen sind asymptomatisch. Gelegentlich kann es aber zur
Dilatation der Gallenwege mit erhöhten Cholestaseparametern oder gar Ikterus kommen.
Abstract
Varicose veins in the hepatoduodenal ligament and hepatic portal are normally due
to cavernous transformation of the portal vein. We present an unusual case of varices
of the common bile duct in an asymptomatic 86-year-old woman who was referred to our
hospital for evaluation of a suspected cholangiocarcinoma. A cholangiocarcinoma could
be excluded, however, and the diagnosis of intramural varicosis of the common bile
duct was made with transabdominal colour Doppler sonography. Sonography showed multiple
dilated vessels in the wall of the common bile duct. Most patients with choledochal
varices are asymptomatic. Choledochal varices may, however, result in dilatation of
the biliary system, causing raised levels of serum alkaline phosphatase and even jaundice.
Key words
Hepatic vein thrombosis - portal hypertension - portal system varicose veins
