Developmental outcomes for neonatal dural arteriovenous fistulas.

Large dural arteriovenous malformations (DAVMs) accompanied by cardiac failure usually carry a poor prognosis with a high risk of morbidity and death. The authors report on the case of a male neonate with a massive DAVM who presented at birth with macrocephaly and high-output cardiac failure. The child initially underwent treatment with surgical clipping of the large main feeding artery. Hydrocephalus, thought to be due to venous hypertension, developed when the boy was 8 months old. The condition resolved after interventional embolization treatment. The patient did not require placement of a ventriculoperitoneal shunt. At 21 months of age, the child had near normal development without any focal neurological deficits.
