RESUMO
We narrate the case of a term baby who presented at 30 h of age in congestive cardiac failure due to vein of Galen aneurysmal malformation. A successful interventional radiology embolisation of the feeding vessels to the aneurysm was performed on day 5. Twenty hours following the procedure, the baby developed significant intraventricular haemorrhage with extension into the brain parenchyma; care was reoriented on day 7 of life after discussion with the parents. Vein of Galen aneurysmal malformation is a rare congenital vascular malformation. It usually manifests in the newborn period with high-output cardiac failure. The death rate is higher in those who present early in the neonatal period. The management of this condition requires a multidisciplinary approach.
