“…Usually, such anomalous origin is from the arch of aorta with an incidence rate of 2.4-5.8% [52,53]. VA originating from the right common carotid artery is rare and was reported only in a few cases with and without the persistence of brachycephalic trunk [3][4][5]. In the present study, we identified right VA arising from the right CCA.…”

“…The vertebral arteries (VAs), critical blood vessels of posterior brain circulation, can exhibit a variety of anatomical variations which have an important implication in medical procedures, specifically in the context of spine surgeries [1,2]. During cervical spine surgeries and endovascular interventions, the VA is at risk of injury due to its close relationship to the vertebrae and the presence of anomalies, such as variant origin [3][4][5], unusual entrance [6][7][8][9][10], and course in the cervical spine [11,12], hypoplasia [13], and tortuosity [14]. These anomalies make it more difficult to identify and access the VAs during surgeries and may lead to inadvertent injuries, which can have detrimental consequences for patients [2].…”

“…VA is known to present variations in its origin [3][4][5] and course [10,11]. Typically, each VA arises from the first part of each subclavian artery and then ascends to reach the level of Appl.…”

We evaluated the incidence of intraforaminal and extraforaminal variations of the vertebral artery (VA) in the Omani population using computed tomography angiography (CTA). CTA results of 579 consecutive Omani patients (1158 VAs) were reviewed retrospectively for the analysis of unusual entrance transverse foramen (UE-V2), midline migration (MM), persistent first intersegmental artery (PFIA), and paracondylar process (PP) variations of VA. The anomalous origin and VA dominance were also determined. The sex and side differences in the incidence of these variations were analyzed using the Chi-square test. The incidence of UE-V2 was observed in 10.44% (121 out of 1158) of cases. The incidence of UE-V2 at different vertebral levels was observed in the sequence of C5 (71%) > C4 (20.7%) > C7 (7.43%) > C3 (0.8%). The incidence of MM variation was 1.29%. PFIA and PP variations were found in 0.17% and 0.60% of cases, respectively. Left-dominant VA was identified in 44.7% (259 out of 579) of subjects. The incidence of VA variations was not significantly associated with either sex or side. Anomalous VA origin from arch aorta (3.5%) and right common carotid artery (CCA) (0.08%) was identified. The incidence of UE-V2 in Omani subjects is comparatively higher than that reported in other Asian populations. A rare case of VA originating from the right CCA was also identified.

“…On each side of the body, the vertebral arteries normally arise from the posterosuperior aspect of the central subclavian arteries, then enter deep into the transverse process. An abnormal origin of the vertebral artery is a rare occurrence [2]. Anomalous origin of vertebral artery from the common carotid artery (CCA) is most commonly associated with an ipsilateral aberrant right subclavian artery (RSCA) from the aortic arch.…”

Anomalous origins of vertebral arteries are rare vascular anomalies that are incidentally identified during computed tomography, magnetic resonance imaging, or digital subtraction angiograms. We present the case of a 45-year-old male who had gangrene of the right ring finger associated with absent radial, ulnar, and brachial artery pulses. A computed tomography angiogram of the upper limb including the arch of aorta showed an aberrant right subclavian artery having near-total stenosis at the origin. An anomalous origin of the right vertebral artery from the right common carotid artery was also noted. This incidental variant anomaly of the vertebral artery was vital in this case as it spared the posterior cerebral circulation from vascular insufficiency complications. It is also important for future head and neck endovascular interventions to avoid inadvertent arterial injury.
