Persistent trigeminal artery as a rare cause of ischaemic lesion and migraine-like headache

Complaints of vertigo and dizziness are common problems referred to otolaryngologists for evaluation. Awareness of uncommon causes of dizziness increases the physician's ability to diagnose and treat these patients. We present the case of a middle-aged woman who presented with episodes of vertigo and symptoms suggestive of vertebrobasilar insufficiency. These symptoms were the result of a persistent trigeminal artery (PTA) and occlusive carotid artery disease. A PTA is a carotid-basilar anastomosis that has been reported to be demonstrated on 0.1% to 0.6% of all cerebral angiograms. Persistence of this vessel usually leads to hypoplasia or agenesis of the ipsilateral posterior communicating artery, and leaves the internal carotid artery as the main source of blood supply to the region of the upper brainstem. The appearance and clinical significance of this unusual condition will be discussed.

We describe a rare case of traumatic persistent trigeminal artery (PTA) - cavernous sinus fistula. Cerebral angiography showed direct communication between the right PTA and the cavernous sinus which was treated by transcathether arterial embolization. Although previous reports have indicated the use of more coils to treat this condition, we successfully treated the patient with only two coils placed near the orifice of the fistula after sufficient anatomical evaluation.

Magnetic Resonance Finding

The trigeminal artery (TA) is the most common embryonic carotid-vertebrobasilar anastomosis to persist into adulthood. It typically extends from the internal carotid artery to the basilar artery. Persistent primitive arteries are usually found incidentally, but are often associated with vascular malformation, cerebral aneurysm and, in case of TA, with trigeminal neuralgia. We present one patient with TA as a cause of trigeminal neuralgia and in other three as an incidental finding, on TC and MR angiograms.
