Fistulous-type vein of Galen malformation phantom model for endovascular training and research.
2016
IntroductionVein of Galen malformation (VGM), a high-flow intracranial arteriovenous shunt, is among the most severe neurovascular diseases in childhood. In many cases untreated children die or survive only severely disabled. Endovascular embolization is the preferred treatment.ObjectiveTo develop a simple fistulous-type VGM phantom model for teaching and training of different endovascular treatment methods and to investigate new treatment options and devices.MethodsAn experimental in vitro pulsatile phantom model was developed imitating a high-flow fistulous-type VGM, which is typical, especially in the neonatal phase. Pressure measurements at different arterial sites were performed before…
Delayed and incomplete treatment may result in dural fistula development in children with Vein of Galen malformation
2017
The association of dural arteriovenous fistulas (DAVF) in children with Vein of Galen malformation (VGM) has recently been reported for the first time. In a larger series of cases treated with transarterial NBCA embolization, 30% had DAVF. We wanted to analyze the development of DAVF in our cohort of children with VGM and to evaluate whether their occurrence depends on different treatment timing and embolic materials. We analyzed 43 VGM cases treated with a combined transarterial and transvenous approach between 2003 and 2016. In our early series until 2011, we used coils solely in 21 children. Since 2012, 22 children were treated with the combination of coils and Onyx. In the early series…
