Abstract OBJECTIVE AND IMPORTANCE A variant type of the primitive trigeminal artery (PTA) is a rare anomalous vessel that originates from the internal carotid artery and directly supplies the territory of the anteroinferior cerebellar artery and/or the superior cerebellar artery. We report a case of trigeminal neuralgia associated with this PTA variant, and we discuss the characteristics of this vessel. CLINICAL PRESENTATION A 51-year-old woman presented with a 10-year history of left paroxysmal facial pain. Magnetic resonance angiography and cerebral angiography demonstrated that an aberrant vessel originating from the left internal carotid artery directly supplied the cerebellum, without a basilar artery anastomosis. INTERVENTION Surgical exploration was performed via a left retrosigmoid approach. A loop of the aberrant vessel, which entered the posterior fossa through the isolated dural foramen, was compressing the trigeminal nerve. This aberrant vessel was displaced medially from the nerve with a prosthesis, with care to avoid kinking and avulsion of the perforating arteries. The patient's neuralgia resolved postoperatively. CONCLUSION Although the PTA variant is frequently associated with intracranial aneurysms, it is extremely rare for the variant to lead to trigeminal neuralgia. During microvascular decompression surgery, surgeons should be careful to prevent injury of the perforating arteries arising from the PTA variant.

Carotid arteriograms on three patients with unilateral pulsatile tinnitus demonstrated an ipsilateral atypical trigeminal artery extending from the cavernous portion of the internal carotid artery to form the posterior inferior cerebellar artery. Illustrations and a dissection of a human fetus with a similar finding show this artery crossing the cochlear nerve near its insertion in the pons. Evidence is presented suggesting that neurovascular compression of the eighth nerve is the source of pulsatile tinnitus in these patients.

Abstract OBJECTIVE Persistent trigeminal arteries are rare and represent a remnant of the fetal carotid-basilar circulation. They typically extend from the internal carotid artery to the basilar artery. An unusual case of a patient with a trigeminal artery originating from the internal carotid artery and terminating as the dominant hemispheric branch of the posterior inferior cerebellar artery is presented. CLINICAL PRESENTATION A 66-year-old woman presented to the emergency department with pulsatile tinnitus, increasing left eye pain, proptosis, conjunctival injection, diplopia, and decreased visual acuity. Conventional contrast-enhanced computed tomographic and magnetic resonance imaging demonstrated findings consistent with a left carotid-cavernous fistula. The patient underwent an emergency diagnostic cerebral angiogram. Besides an indirect carotid-cavernous fistula on the left side, a right-sided persistent trigeminal artery terminating as the dominant hemispheric trunk of the posteroinferior cerebellar artery was incidentally noted. The vermian branch of the right posteroinferior cerebellar artery arose from the ipsilateral vertebral artery, whereas duplicate superior cerebellar arteries supplied the left posteroinferior cerebellar artery region. INTERVENTION The patient was treated for the indirect carotid-cavernous fistula with detachable platinum coils and N-butyl cyanoacrylate, resulting in the resolution of her symptoms. CONCLUSION We report a case of a persistent trigeminal artery supplying only the cerebellar hemisphere. The clinical significance of this anomaly relates to its role in endovascular therapeutic and surgical complications and the paradoxical lesions in the cerebellum that occur as a result of carotid disease. We also discuss the Saltzman classification of persistent trigeminal arteries and their variants.

✓ A case of coexisting proatlantal intersegmental artery and primitive trigeminal artery is described. These anomalies were incidental findings in a patient with hemiparesis due to occlusion of the middle cerebral artery. The primitive trigeminal artery had an asymptomatic aneurysm at its origin from the internal carotid artery.

Background: The prevalence of persistent primitive trigeminal artery (PPTA) has been reported to be 0.1–0.6%. We report the successful recanalization of internal carotid artery (ICA) without embolization to new vascular territory (ENT) using a combined technique in a case of ICA occlusion with PPTA. Case Description: A 65-year-old female presented with sudden consciousness disorder. The Glasgow Coma Scale score was 7 (E1, V1, M5) and National Institutes of Health Stroke Scale score was 28. Magnetic resonance diffusion-weighted imaging showed areas of high signal intensity in the left frontal lobe, parietal lobe, insular cortex, and corona radiata. Magnetic resonance angiography showed occlusion of the left ICA distal to a PPTA. We performed mechanical thrombectomy (MT) using a combined technique with a balloon guide catheter (BGC), aspiration catheter, and stent retriever and achieved complete recanalization without ENT. The patient experienced a good postoperative recovery course. At 6 months, her Modified Rankin Scale score was 2. Conclusion: MT using a combined technique with BGC would be useful to prevent embolization to the posterior circulation through the PPTA in cases of ICA occlusion with PPTA.
