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