Bilateral persistent trigeminal arteries with unilateral trigeminal artery to cavernous sinus fistula. A case report

Interv Neuroradiol. 2013 Sep;19(3):339-43. doi: 10.1177/159101991301900311. Epub 2013 Sep 26.


A 59-year-old man who denied a history of trauma presented with left pulsatile tinnitus and left orbital swelling for six months. Digital subtraction angiography showed a left persistent trigeminal artery (PTA) with a trigeminal artery to cavernous sinus (trigeminal-cavernous sinus) fistula and a right PTA. Transarterial detachable coil embolization of the left trigeminal-cavernous sinus fistula was performed, and the symptoms subsided. There has been no report of bilateral PTAs with a spontaneous fistula connected from one PTA to the ipsilateral cavernous sinus. This paper reports such a rare circumstance.
