“…Additionally, Uchino et al have demonstrated two lateral type PTAs, but no medial type PTA, supplying the superior cerebellar artery (neural structures) on magnetic resonance angiography (MRA). 12) Suttner et al hypothesized that the lateral and medial type PTA may be of different carotid-vertebrobasilar anastomosis origin, and that the branches of the MHT may be the remnant of the medial type PTA. 19) Some authorities support this view as well, stating that the lateral artery of the clivus is the remnant of the trigeminal artery.…”

“…23) Based on analysis with a large number of MRA, the association of PTA/PTA variant with intracranial aneurysm, arteriovenous malformation, Moyamoya disease, Sturge-Weber syndrome, and mental retardation was not identified. 11,12) Rarely, PTA and its variant is associated with cranial nerve compression syndrome such as trigeminal neuralgia or oculomotor palsy. 24–27) Of note is the association of PTA with a much higher frequency (12–16%) than expected in children with PHACE syndrome (acronym indicating malformative abnormalities occurring with infantile hemangioma in the face: P = posterior fossa; H = hemangioma; A = arterial; C = cardiac; E = eye.…”

The primitive carotid-vertebrobasilar anastomoses are primitive embryonic cerebral vessels that temporarily provide arterial supply from the internal carotid artery to the longitudinal neural artery, the future vertebrobasilar artery in the hindbrain. Four types known are the trigeminal, otic, hypoglossal, and proatlantal intersegmental arteries. The arteries are accompanied by their corresponding nerves and resemble an intersegmental pattern. These vessels exist in the very early period of cerebral arterial development and rapidly involute within a week. Occasionally, persistence of the carotid to vertebrobasilar anastomosis is discovered in the adult period, and is considered as the vestige of the corresponding primitive embryonic vessel. The embryonic development and the segmental property of the primitive carotid-vertebrobasilar anastomoses are discussed. This is followed by a brief description of the persisting anastomoses in adults.

Background:Although persistent trigeminal artery (PTA) is uncommonly identified, knowledge of this structure is essential for clinicians who interpret cranial imaging, perform invasive studies of the cerebral vasculature, and operate this region.Methods:A review of the medical literature using standard search engines was performed to locate articles regarding the PTA, with special attention with anatomical descriptions.Results:Although anatomical reports of PTA anatomy are very scarce, those were analyzed to describe in detail the current knowledge about its anatomical relationships and variants. Additionally, the embryology, classification, clinical implications, and imaging modalities of this vessel are extensively discussed.Conclusions:Through a comprehensive review of isolated reports of the PTA, the clinician can better understand and treat patients with such an anatomical derailment.

“…In magnetic resonance (MR) angiography examinations, PTA with its variants is detected in about 0.5%. Uchino et al [24] reported that out of 3626 MR angiographic examinations, 12 (0.34%) cases of PTA and 6 (0.17%) cases of PTA variants were found. Another large study examining 16,415 MR angiographies revealed that the incidence of both PTA and its variants was 0.68% [18].…”
