“…The incidence of 0.21% in our study was low, but it was almost the same as the reported 0.2% incidence of the persistent trigeminal artery, the most common type of carotid-vertebrobasilar anastomosis. 10 To our knowledge, ours is the first report of the incidence of nonbifurcating cervical carotid artery detected by MRA.…”

“…Such anastomoses begin to form at the 4-to 5-mm embryo stage and disappear at the 7-to 12-mm embryo stage (1)(2)(3)(4). Th e fi rst anastomosis to involute is the otic artery, followed by the hypoglossal, trigeminal, and proatlantal intersegmental arteries (4).…”

“…Many Saltzman variants, sometimes referred to as Saltzman type 3, have subsequently been described (12, 41,78). The PTA variant directly joins into a cerebellar artery (42). It arises from the ICA and terminates directly without anastomosing with BA as SCA (Saltzman Type 3a), AICA (Saltzman Type3b), or PICA (Saltzman Type3c) (2,8,15,28,50,51, 71,78,79).…”

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.
