“…Clinical evidence of a compressive effect of the BA has been confirmed by evoked potentials. [37] Therefore, mass effect might be considered in this group of patients presenting with symptoms of brainstem dysfunction in the absence of demonstrable ischemia. Persistent embryonic intracranial arteries may be more common in patients with moyamoya disease.…”

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.

“…The anatomy of the PTA is inconstant and varies from a partial to a complete intrasellar course [16,23] . A relation with clinical neurological symptoms was suspected in the past [7,8,15,21] . PTA may be found on neuroimaging.…”

Variants such as PTA are rare and routine preoperative imaging for pituitary procedures does not always include studies to detect this vascular anomaly. The occasional intraoperative detection of a PTA during an endoscopic transsphenoidal procedure can be managed; almost any surgical manipulation is possible and pituitary surgery can be successfully completed, provided the surgeon is aware of the possible existence of this variant and its irregular anatomical course. However, the presence of a PTA may have dramatic consequences if surgery is directed to the lateral parasellar region, as for intracavernous lesions; in these cases a complete neuroradiological study including MRI-angiography and possibly CT-angiography is advised.

Trigeminal artery: a review of normal and pathological features

et al. 2011

The persistent primitive trigeminal artery, as the most commonly carotid-vertebrobasilar anastomosis, has a reported incidence of 0.03-2.2% in the literature. There is female sex predilection, and it may be discovered in patients of any age, on either side, and in association with many vascular variants. Although the significance of persistent primitive trigeminal artery regarding the development of an aneurysm or association with another pathological condition may not be clear, its (ab)normal morphology is the inspiration for anatomists, especially for neurosurgeons, before planning diagnostic and therapeutic procedures.
