Background: Vein of Galen malformations (VGM) are rare congenital arteriovenous fistulas that usually present with heart failure in the neonate. Endovascular treatment options in the past have utilized coils, balloons, and acrylics. Case report: We present, for the first time in the literature, a case of an infant with VGM treated initially with staged coil embolizations followed 1 year later by the transarterial and transvenous catheter based injection of Onyx-18 (ethylenevinylalcohol copolymer) in a single treatment session. The fistula was eliminated, and the infant's cardiopulmonary symptoms were improved.
