Vein of Galen malformation
This is a typical example of a vein of Galen malformation.
The patient was treated by endovascular occlusion of the larger feeding vessels. An intraprocedural arterial bleed was rapidly controlled. In the immediate postprocedural period the cardiovascular status improved. Ongoing high-output state will necessitate further procedures on a staged basis.
