title: Transcatheter embolization of congenital hepatic arteriovenous malformation using ethylene-vinyl alcohol copolymer (Onyx).
abstract: A male infant with high-output heart failure who had been found to have a     hepatic arteriovenous malformation by ultrasound imaging was referred to our     center (Department of Diagnostic and Interventional Radiology, Imam Khomeini     Hospital, Tehran University of Medical Sciences, Islamic Republic of Iran) for     further evaluation. Computed tomography angiography revealed a large hepatic     arteriovenous malformation with feeders originating from enlarged hepatic     arteries and draining to enlarged hepatic veins. We performed a transcatheter     embolization of the anomaly using ethylene vinyl alcohol copolymer (Onyx) during     a single session. The cardiac function of the infant rapidly improved after the     procedure. Over the 19 months of follow-up, his cardiac output remained stable     and within the normal limits, and no complications were detected.
