see Dural arteriovenous fistula.
The dural arteriovenous malformation has been replaced by dural arteriovenous fistula (DAVF), which represents the true angioarchitectural designation. Correct nomenclature can profoundly impact treatment; when we hear about a sexagenarian with a vein of Galen malformation we know the diagnosis is most likely a vein of Galen region DAVF, with completely different ramifications. Other times we adopt new terms simply because they more accurately define the state, even though the older term is widely used and perhaps not quite inaccurate.
