“…2) Although pontine branches from the trunk of the PPTA were usually found in the brains of 4-, 6-, and 8-month-old fetuses, these arteries are usually occluded before birth. 12) In our case, the PPTA was of the adult type. During surgery, we were not sure whether the perforating artery from the PPTA was clinically significant, so we tried to preserve the patency of the PPTA to prevent ischemic lesions in the brain stem.…”

A 62-year-old man presented with a very rare cerebral aneurysm arising from the trunk of the persistent primitive trigeminal artery (PPTA) manifesting as subarachnoid hemorrhage. Angiography showed a saccular aneurysm at the curved mid-section of the trunk of the left PPTA of the adult type. The patient underwent surgery via the left subtemporal approach, and the aneurysm was successfully eliminated by clipping without sequelae. Aneurysm formation at this point was probably due to hemodynamic stress. The perforating arteries from the PPTA may be important in supply of the hindbrain, so PPTA patency should be preserved if possible.

“…Persistent trigeminal artery (PTA) is the most common of the primitive carotid-basilar anastomoses that persist into adulthood, with an estimated incidence of 0.1 to 1.0% on cerebral angiograms (17,20,36,39,47,52,67,70). A number of cases of PTA and its variants found at autopsy (21,30, 34,52,60,67,70,82), on cerebral angiograms (2,6,7,17,27, 35,73,85), and on MRI and MRA scans (7,18,63) demonstrate the anatomy (30,39,52,67) of this primitive anastomosis and its relationship to various vascular diseases (1,16,19,20,25,30,36,44,47). …”

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.

“…This was in contrary to the fetal form of the trigeminal artery which differs from the adult form by possessing branches supplying the pons as well as branches anastomosing with the superior cerebellar artery, internal auditory artery, and the posterior inferior cerebellar artery [Khodadad, 1976]. This feature, how ever, may not be surprising because the hypo glossal artery functions for all practical purposes like a large vertebral artery which continues as the basilar artery and gives all the necessary branches to the brain stem and the cerebellum.…”

The hypoglossal artery in a human fetus studied by post mortem angiography and microdissection is described. In contrast to the fetal form of the trigeminal artery which differs from the adult form by possessing branches supplying the pons and anastomotic branches to the cerebellar and internal auditory arteries, there were no major anatomical differences between the fetal and the adult form of the hypoglossal artery. The incompetence of the vertebral arteries in the presence of a hypoglossal artery is also emphasized.
