Anatomical features and clinical relevance of a persistent trigeminal artery.

Alcalá-Cerra G, Tubbs RS, Niño-Hernández LM - Surg Neurol Int (2012)

Bottom Line: 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.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.

ABSTRACT

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.

Three-dimensional computed tomographic (CT) angiography showing a lateral petrosal variant of persistent trigeminal artery (PTA) as it exits immediately superior to the cranial end of petroclival fissure; just medial to Meckel's cave and closely related with the ophthalmic branch of trigeminal nerve. It courses posterior and medially to reach the basilar artery before its bifurcation. It relationships with posterior communicating artery (PcomA) and anterior choroidal artery (AchoA) are also showed

Mentions: On the basis of its anatomical relationships, Salas et al. purposed to classify PTA into a medial sphenoid variation where it travels into the sella turcica and perforates the dura mater in a groove lateral to the clivus, or sometimes through the dorsum sellae and a lateral petrosal variation where the vessel runs together with the sensory roots of the trigeminal nerve and exits Meckel's cave below the petroclinoid ligament [Figures 2 and 3].[4353] The former appears to be the most frequent variation occurring up to 11 times more often than the medial variation.[343555]
