Congenital intrahepatic arterioportal fistula presenting as severe undernutrition and chronic watery diarrhea in a 2-year-old girl

Intrahepatic arterioportal fistula (IAPF) is a rare cause of portal hypertension in young children. We report the case of a 2-year-old girl with severe undernutrition, chronic watery diarrhea, and gastrointestinal bleeding because of a congenital intrahepatic arterioportal fistula. Radiographic embolization and surgical ligation of the left hepatic artery were attempted, with no resolution of the symptoms. So, a left lobectomy was performed, with excellent results and prompt disappearance of the diarrhea. Hepatectomy should be considered as a definitive and reliable. therapy for congenital IAPF.
