Management of vein of Galen malformations. A review based on five neurosurgically treated cases and literature reports.

The high morbidity and mortality associated with the management of vein of Galen aneurysmal malformations (VGAM) continues to pose a tremendous challenge to the neurosurgeon as well as to the attending interventional radiologist. Since 1985, five patients with VGAM have been referred to the neurosurgical unit of the University of Cologne, two neonates, one infant and two adults. Four patients underwent direct operation and two patients received a shunt. The treatment was performed without mortality. A review of the literature reflects no substantial difference between neurosurgical treatment during the last 15 years (mortality 10%) and endovascular treatment (best series mortality 6%).
