Posttraumatic Trigeminal-Cavernous Fistula

Posttraumatic Trigeminal-Cavernous Fistula

Chang Wei Zhang et al. World Neurosurg. .


Introduction: Persistent trigeminal artery is the most frequent embryonic communication between the vertebrobasilar and carotid systems. To the best of our knowledge, posttraumatic trigeminal-cavernous fistula is rarely reported in the literature.

Case presentation: We present a 47-year-old man with posttraumatic trigeminal-cavernous fistula, which we treated using Onyx embolization.

Conclusion: Even though preservation of the parent artery is generally considered a desirable goal in fistula treatment, in special cases such as Salzmann type 2 anatomy plus a unique fistulous orifice accompanied by external carotid-cavernous fistula, it is required to embolize the persistent trigeminal artery and cavernous sinus.
