Barrow Classification (Carotid-Cavernous Fistula)
The Barrow classification of carotid-cavernous fistula (CCF), by the arterial supply and flow, types A/B/C/D.

Example
- Barrow type
- A - direct ICA-to-cavernous-sinus shunt (high-flow)
Result: Barrow type A: direct high-flow shunt between the internal carotid artery and the cavernous sinus.
The tool opens with these values already filled in. Replace them with your own.
What the result means
- Type A
- Direct high-flow ICA-to-cavernous-sinus shunt (often traumatic).
- Type B
- Dural shunt from ICA meningeal branches.
- Type C
- Dural shunt from ECA meningeal branches.
- Type D
- Dural shunt from both ICA and ECA meningeal branches.
What you enter
- Barrow type
