We report the case of a 10-month-old boy with an enlarged head circumference and severe motor developmental delay. MRI showed a vein of Galen malformation (VGAM) with a heavily dilated median prosencephalic vein. Digital subtraction angiography confirmed a mural type VGAM with three feeding arteries arising from the posterior cerebral arteries. Due to the short length of the feeding arteries and the high flow, occlusion of the feeding vessels with detachable coils was not possible because of repeated coil dislocation into the dilated vein. Embolization of the three feeding vessels was then performed with a Woven EndoBridge single layer device (WEB SL17). In two arteries complete occlusion was accomplished with the WEB alone and in one artery additional deployment of two coils was necessary. Follow-up imaging at day 1 after treatment as well as 3 and 9 months after embolization showed persistent occlusion.
