Vein of Galen malformation is the most common form of symptomatic cerebrovascular malformation in neonates and infants. This anomaly may be diagnosed prenatally by several imaging modalities. High-riks neonates with vein of Galen malformations presenting with cardiac failure have high morbidity and mortality; however, endovascular therapy with modern neuroanesthetic and neurointensive care can provide good outcomes even in these neonates. We report here a female full-term newborn with a vein of Galen malformation who presented with cardiac failure within 24 hours post-partum and was treated with transumbilical embolization.
