Congenital intrahepatic arterioportal fistula: an unusual cause of portal hypertension treated by coil embolization in an infant.

摘要

Hepatic arterioportal fistula is an unusual cause of portal hypertension (PH) and massive gastrointestinal bleeding in an infant. Arterioportal fistulas can be located in the liver or extrahepatically. They are commonly acquired and develop secondary to cirrhosis, hepatic neoplasms, blunt or penetrating trauma, percutaneous liver biopsy, transhepatic cholangiog-raphy, Kasai portoenterostomy, segmen-tal liver transplantation, Ehlers-Danlos syndrome, Rendu-Osler-Weber syndrome and hereditary hemorrhagic telan-giectasia [2,6,8].
