Abstract
Vein of Galen malformations are congenital high-flow vascular malformations that often present with heart failure, hydrocephalus, developmental delay, and intracranial hemorrhage. Because open surgical treatment is associated with high morbidity and mortality, endovascular embolization is increasingly becoming the preferred method of intervention. However, embolization of these lesions can be difficult because of their high-flow nature. The use of adenosine-induced cardiac standstill for treatment of vein of Galen malformations has not been previously described in neonates. The authors describe 3 treatments in 2 patients that demonstrate that the use of adenosine is well tolerated and allows safe transarterial embolization of high-flow vein of Galen malformations in the pediatric population.
