“…According to the angiographic classification of the PTA, 8) our present case is the intermediate type, because the left posterior communicating artery (PcomA) is a fetal type and supplies the left posterior cerebral artery (PCA), and the right PcomA is an adult type, and both SCAs and the right PCA are supplied by the PTA. The anomalous artery, with a diameter as large as that of the contralateral AICA, originated directly from the PTA to supply the cerebellar territory of the AICA.…”

Fig. 1 Magnetic resonance angiograms, axial view(A) and lateral view (B), revealing the primitive trigeminal artery (PTA) (arrow) originating from the posterolateral aspect of the left internal carotid artery and connecting with the basilar artery, and also an anomalous small artery (arrowhead) directly originating from the PTA. 194Neurol Med Chir (Tokyo) 46, 194¿197, 2006 AbstractA 31-year-old man presented with typical trigeminal neuralgia caused by an anomalous variant type of anterior inferior cerebellar artery (AICA) directly branching from the primitive trigeminal artery (PTA). Three-dimensional computed tomography angiography, magnetic resonance angiography, and magnetic resonance cisternography disclosed that this anomalous artery originated from the PTA and coursed to the AICA territory of the cerebellum. Microvascular decompression surgery disclosed the trigeminal nerve compressed by this AICA variant together with the superior cerebellar artery. These arteries were successfully transpositioned to decompress the nerve. Careful and thorough inspection around the trigeminal nerve verified that the PTA did not conflict with the nerve. This unusual case was caused by compression of the trigeminal nerve from the AICA directly originating from the PTA, without the more common involvement of the PTA.

“…Saltzman (68) classified one case as a combination of the two types; PCoA supplied the PCA on the same side of the PTA and the PTA supplied both SCAs and the PCA on the opposite side. A similar case was reported in 1974 by Parkinson and Shields (60) who demonstrated both angiographic and anatomic features of a PTA filling both SCAs and the contralateral PCA with a fetal PCoA on the same side of the PTA supplying the ipsilateral PCA; a description which corresponds to a combination of the Saltzman Types I and II.…”

The trigeminal artery is the largest of the fetal carotid-basilar anastomotic arteries, and it persists for the longest embryonic period. The artery usually involutes after the development of the posterior communicating artery. The exact causes of persistence of this primitive vessel into adulthood are not completely clear. Angiographic and anatomical descriptions of the various persistent trigeminal artery (PTA) configurations and their relation to the remainder of the cerebrovascular tree and the other surrounding structures have been reported. Persistent trigeminal artery can be associated with many other vascular anomalies and disorders including aneurysms, arteriovenous malformations and carotidcavernous fistulae. A thorough understanding of the anatomical and angiographic features of this persistent embryonic arterial channel is of utmost importance when making therapeutic decisions and embarking on surgical or endovascular intervention for any pertinent pathological condition. We review the embryology, angiographic features, microsurgical anatomy and associated vascular anomalies and disorders of the persistent trigeminal artery.

“…1) There are three angiographic conditions related to a PPTA. 8) Our case was type 2, with the distal basilar, superior cerebellar, and posterior cerebral arteries filled via the PPTA, and the posterior cerebral artery filled by the ICA via the posterior communicating artery. The PPTA originates just before or at the point where the ICA enters the cavernous sinus and runs with the sensory root of the trigeminal nerve and passes through the abducens nerve.…”

A 17-year-old woman presented with a rare aneurysm at the junction of the persistent primitive trigeminal artery (PPTA) and the internal carotid artery (ICA) manifesting as left abducens nerve paresis. The aneurysm and the ICA were both successfully occluded with coils. The balloon occlusion test used the HyperForm balloon microcatheter to seal the PPTA and ICA, which is very important to determine the optimal treatment strategy for a PPTA aneurysm.
