“…Embryologically, the development of the vertebral artery is contributed by the cervical intersegmental arteries, which normally originate from the subclavian artery [5]. Initially, these arteries are the major source of blood supply to the cervical nerves and spinal cord.…”

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.

“…Many publications have reported abnormal VAs with different genesis including trunk of thyrocervical artery, brachiocephalic artery, common carotid artery, and the aorta [9][10][11][12]. However, there are less than 5 studies which reported that VA originates from external carotid artery [8,[13][14][15]. Elevated risk for cerebrovascular accidents including ath-for cerebrovascular accidents including ath-for cerebrovascular accidents including atherosclerosis, intracranial vascular deformities, arterial cutting up and resulting intracranial complexities due to confusion of the blood flow proceeding from aberrant origin of the VAs have been illustrated in many studies [8][9][10][11][12][13][14][15][16].…”

Background: The vertebral arteries originate from the root of the neck as the first branches of the subclavian arteries. Variations of vertebral arteries are congenital anomalies occurring during embryonic development. Anatomic variations of the left vertebral artery are clinically symptomless and recognized incidentally during angiographic assessments or imaging techniques so the diagnosis of these anomalies is a serious challenge. Anomalous origin of vertebral arteries may lead to neurologic disorders. It is, thus, important to identify variations of the large vessels of the aortic arch when planning neck and cervical spine interventions and diagnostic radiology. For this reason, we would like to present this rare case of left vertebral artery showing a different origin. Case report: In this work, we describe a 60-year-old female patient with headache, lethargy and blurred vision. We employed magnetic resonance angiography for both the brain and neck. There was no lesion in the brain. Incidentally, we found that the root of the left vertebral artery was anatomically aberrant. The left vertebral artery arose from the nearest section of the left external carotid artery, next to the bifurcation of the left common carotid artery, which is a rare variation. Conclusion: Understanding the state of anomalous variations of the origin of the vertebral artery might have crucial implications in angiographic and surgical procedures. It is beneficial to perform more screening with noninvasive studies like neck magnetic resonance angiography in clinical cases with potential symptoms coexisting with other diseases in order to predict possible future problems in intracranial and extracranial interventions. Keywords: Vertebral artery; external carotid artery; anatomic variation; magnetic resonance angiography.

Background Congenital aortic arch anomalies are commonly encountered during neurointerventional procedures. While some anomalies are identified at an early age, many are incidentally discovered later in adulthood during endovascular evaluations or interventions. Proper understanding of the normal arch anatomy and its variants is pivotal to safely navigate normal aortic arch branches and to negotiate the catheter through anomalies during neurointerventional procedures. This is particularly relevant in the increasingly “transradial first” culture of neurointerventional surgery. Moreover, some of these anomalies have a peculiar predilection for complications including aneurysm formation, dissection, and rupture during the procedure. Therefore, an understanding of these anomalies, their underlying embryological basis and associations, and pattern of circulation will help endovascular neurosurgeons and interventional radiologists navigate with confidence and consider relevant pathologic associations that may inform risk of cerebrovascular disease. Methods Here, we present a brief review of the basic embryology of the common anomalies of the aortic arch along with their neurological significances and discuss, through illustrative cases, the association of aortic arch anomalies with cerebral vascular pathology. Conclusions Understanding the aortic arch anomalies and its embryological basis is essential to safely navigate the cerebral vascular system during neurointerventional surgeries.
