We describe a case of intra-arterial treatment (IAT) of acute posterior circulation occlusion in a patient with a persistent primitive trigeminal artery (PPTA). The patient presented with an acute left sided hemiparesis and loss of consciousness (Glasgow coma score of 5). Computed tomography angiography showed an acute occlusion of the right internal carotid artery (ICA), the PPTA, distal basilar artery (BA), right posterior cerebral artery (PCA), and right superior cerebellar artery (SCA). Stent-retriever assisted thrombectomy was not considered possible through the hypoplastic proximal BA. After passage of the proximal ICA occlusion, the right PCA and SCA were recanalized through the PPTA, with a single thrombectomy procedure. Ten days after intervention patient was discharged scoring optimal EMV with only a mild facial and left hand paresis remaining. PPTA is a persistent embryological carotid–basilar connection. Knowledge of existing (embryonic) variants in neurovascular anatomy is essential when planning and performing acute neurointerventional procedures.

Here we describe the case of a patient with a wide-necked unruptured aneurysm arising at origin of a persistent primitive trigeminal artery (PTA) variant from the right internal carotid artery (ICA), supplying the territory of the right superior cerebellar artery and the anterior inferior cerebellar artery. To preserve the ICA and the PTA variant, coil embolization of the aneurysm was performed using a double-balloon remodeling technique (HyperForm™ and Hyper-Glide™ Occlusion Balloon Systems; ev3 Endovascular Inc., Irvine, CA, USA). The association of a PTA variant with an aneurysm is very rare. To our knowledge, this is the first description of the use of coil embolization using double-balloon remodeling to treat a PTA variant aneurysm. This technique permits complete embolization and reduces the risk of cerebral and cerebellar ischemia.

✓ Two cases of moyamoya disease associated with persistent primitive trigeminal artery (PTA) are reported. The first patient was a 44-year-old man who experienced a sudden severe headache brought about by an intracerebral hematoma in the left temporoparietal lobe. Four-vessel study showed a right-sided PTA and moyamoya disease. The second patient was a 56-year-old woman with similar symptoms and a hematoma in the right temporoparietal lobe. Four-vessel study showed a left-sided PTA and moyamoya disease. Among the 212 PTA cases reported in the literature, none has been associated with moyamoya disease. Moreover, there are no cases of moyamoya disease among the 119 cases of persistent primitive hypoglossal artery (PHA), which is thought to be a vascular anomaly fundamentally similar to PTA. None of the 907 cases of moyamoya disease reported in Japan has been associated with either PTA or PHA. Nonetheless, the embryonic stage when PTA or PHA normally disappears partially overlaps that period when moyamoya-like vascular anomalies have been thought to arise. The possible developmental relationship beween these two varieties of vascular abnormality is discussed.

✓ Primitive trigeminal artery (PTA) is an extremely rare cause of tic douloureux. None of the reports on PTA variant, which is an anomalous cerebellar artery arising from the internal carotid artery without anastomosis to the basilar artery, has suggested the possibility of this vessel causing tic douloureux. Eight cases of tic douloureux are reported in which a PTA or PTA variant was found during microvascular decompression (MVD). These cases were derived from a series of 1257 patients treated with MVD for tic douloureux. In one patient, the neuralgia was caused by a combination of vessels: a PTA, the superior cerebellar artery, and the anterior inferior cerebellar artery. In the other seven cases, a PTA variant was compressing the root entry zone of the trigeminal nerve. All eight patients gained excellent pain relief after MVD of the root entry zone. The significance of PTA's and PTA variants as the cause of tic douloureux and the effectiveness of MVD in the management of such cases are discussed.
