Intracranial dural arteriovenous fistula classification

For spinal see Spinal vascular malformation classification.

There are numerous intracranial dural arteriovenous fistula classifications. Borden 1) and Cognard 2) 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.)

Cognard classification

Cognard classification: Probably the most widely used classification system for dural arteriovenous malformations.

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 3).
