Intracranial Hemorrhage in Infants Associated With Congenital Biliary Dilatation : A Case Report

Abstract

Vitamin K deficiency bleeding in late neonates and infants is roughly classified into two groups whether in association with being human milk-fed or not, and results in intracranial hemorrhage with considerable frequency. Intracranial hemorrhage in biliary atresia resulting from vitamin K malabsorption and liver dysfunction has been reported by many authors. A 2-month-old boy presenting with congenital biliary dilatation developed bradypnea and unconsciousness. Brain CT scan showed high density areas in the right lateral lobe. He was diagnosed with acute intracranial hemorrhage due to vitamin K deficiency by a coagulation study and operated on for intracranial hemorrhage because of a deteriorating general condition. We performed a definitive operation on him for congenital biliary dilatation because of persisting liver dysfunction. Congenital biliary dilatation in late neonates and infants should be considered with risk of vitamin K deficiency bleeding.
