Transarterial detachable coil embolization combined with ipsilateral intermittent carotid oppression for traumatic carotid-cavernous fistula with small fistula

One case of traumatic carotid-cavernous fistula （TCCF） with small fistula treated by transarterial detachable coil embolization was reported. The intermittent ipsilateral carotid compression was used to identify the final blocking of the residual fistula. The follow-up digital subtraction angiography showed that the TCCF was cured finally. From this case, we conclude that this method may be an effective way to treat TCCF with small fistula.
