For spinal see [[Spinal vascular malformation classification]].

There are numerous [[intracranial dural arteriovenous fistula ]] classifications. [[Borden]] 
((Borden JA, Wu JK, Shucart WA. A proposed classification
for spinal and cranial dural arteriovenous
fistulous malformations and implications for treatment.
J Neurosurg. 1995; 82:166–179))
and [[Cognard]] 
((Cognard C, Gobin YP, Pierot L, et al. Cerebral dural
arteriovenous fistulas: clinical and angiographic
correlation with a revised classification of venous
drainage. Radiology. 1995; 194:671–680))
are amongst the more widely used grading schemes. Cortical venous drainage is the defining angiographic feature that distinguishes benign (low-grade) from aggressive (high-grade) fistulas. (Borden I, Cognard I, and Cognard IIa are low-grade, all others are high-grade.)

Cavernous sinus DAVFs are the most common site in the series of Signorelli et al. other locations in order of frequency are transverse-sigmoid sinus, tentorial, anterior cranial fossa, spinal and foramen magnum
