“…The APA rarely arises from the proximal ICA, and in the case of acquired occlusion of the ICA at its origin, the APA serves as an important collateral pathway from the VA. 12 Lasjaunias et al 13 reported that the OA is formed from the proatlantal artery and arises from the primitive ICA, ECA, and VA at points determined by the sites of regression. Thus, the OA rarely arises from the ICA 14 or VA, as in our case 6. We suggest that in the 4 previously reported patients in whom the OA was not visualized, the OA may have arisen from the VA. Figure 3 schematically illustrates our proposed hypothesis regarding this anomaly.…”

“…However, the origin and configuration are quite variable, and the origin may be the internal carotid artery. 8,14) The meticulous anatomical dissection and identification of vital structures needed to minimize postoperative complications can only be achieved with a bloodless field. 10) If the ascending pharyngeal artery arises close to the origin of the external carotid artery proximal to the lingual artery, carotid bifurcation, and internal carotid artery, this vessel must be identified to ensure that no troublesome backbleeding occurs during plaque removal.…”

Carotid endarterectomy (CEA) is the main treatment for atherosclerotic plaque of the cervical internal carotid artery. The surgical anatomy of the carotid arteries was studied in the carotid triangle of 49 cadavers. The carotid bifurcation was located at the level of the lower third of C-3. The superior thyroid artery arose from the anterior wall of the external carotid artery in 70% of specimens and from the distal portion of the common carotid artery in 30%. The lingual artery arose as a separate trunk between the origins of the superior thyroid and facial arteries in 81% of specimens, with the facial artery from a common trunk in 18%, and with the superior thyroid artery in 1%. The occipital artery arose from the posterior aspect of the external carotid artery above the level of origin of the facial artery in 57% of specimens, between the origins of the facial and lingual arteries in 32%, and below the origin of the lingual artery in 11%. The origin of the occipital artery was positioned low and the distal portion of the occipital artery was crossed by the hypoglossal nerve in 20%. The ascending pharyngeal artery arose from the posterior wall of the external carotid artery above the level of origin of the lingual artery in 66% of specimens, below the origin of the lingual artery in 9%, from the proximal portion of the occipital artery in 19%, from the carotid bifurcation in 2%, and from the internal carotid artery in 2%. The branches of the external carotid artery are the key landmarks for adequate exposure and appropriate placement of cross-clamps on the carotid arteries. It is necessary to understand the surgical anatomy of the carotid arteries to carry out successful removal of plaque and minimize postoperative complications in a bloodless surgical field.

“…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). Among the PTA variants, the majority fall under Type 3b with termination at the AICA; with types 3a and 3c being extremely rare in the literature (2,65).…”

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.
