“…There were 43 (4.5%) patients with cerebrovascular lesions, including cerebral infarcts [ 9 - 24 ] in 17 (39.5%), cerebral vascular aneurysms without cerebral hemorrhage [ 14 , 23 , 25 , 26 ] in 4 (9.3%) and cerebral hemorrhage in 18 (41.9%), and ischemic cerebrovascular disease [ 25 ] , transient ischemic attack [ 14 ] , partial thrombus detected in the left internal jugular vein and sigmoid sinus [ 27 ] , and vertebrobasilar insufficiency [ 28 ] in 1 (2.3%) patient each. The 18 cerebral hemorrhages were subarachnoid hemorrhage in 14 (77.8%) [ 29 - 39 ] (8 were associated with an aneurysm of the cerebral artery [ 29 - 31 , 33 , 35 - 37 , 39 ] ), intraventricular hemorrhage in 2 (11.1%) [ 40 , 41 ] and intracerebral hemorrhage [ 42 ] and subarachnoid and intraventricular hemorrhages [ 43 ] in 1 (5.6%) patient each.…”

Aberrant origin of vertebral artery is rare. The anatomical features and clinical significance of this lesion remain to be clarified. A comprehensive collection of the pertinent literature resulted in a cohort of 1286 cases involving 955 patients and 331 cadavers. There were more left than right and more unilateral than bilateral aberrant vertebral arteries. Patients with aberrant origin of vertebral artery were often asymptomatic and in only 5.5% of the patients their symptoms were probably related to the aberrant origin of vertebral artery. The acquired cardiovascular lesions were present in 9.5% of the patients, 20.9% of which were vertebral artery-associated lesions. Eight (0.8%) patients had a vertebral artery dissection. Logistic regression analysis showed significant regressions between bovine trunk and left vertebral artery (P=0.000), between the dual origins of vertebral artery and cerebral infarct/thrombus (P=0.041), between associated alternative congenital vascular variants and cervical/aortic dissection/atherosclerosis (P=0.008). Multiple logistic regression demonstrated that side of the aberrant origin of vertebral artery (left vertebral artery) (P=0.014), arch branch pattern (direct arch origin) (P=0.019), presence of the common trunk (P=0.019), associated acquired vascular disorder (P=0.034) and the patients who warranted management (P=0.000) were significant risk predictors for neurological sequelea. The patients with neurological symptoms and those for neck and chest operations/ interventions should be carefully screened for the possibility of an aberrant origin of vertebral artery. The results from the cadaver metrology study are very helpful in the design of the aortic stent. The arch branch pattern has to be taken into consideration before any maneuver in the local region so as to avoid unexpected events in relation to aberrant vertebral artery.

“…A detailed knowledge of the anomalous origin of the major arteries is important in patients who have to undergo four vessel angiography. If a VA cannot be found in its original position, such a variation must be considered (Ligege and Scholtz 2004). This is the reason behind a routine angiography before catheterization of carotid or vertebral arteries.…”

Las variaciones de los principales vasos arteriales son de importancia clínica. La arteria vertebral (VA) normalmente surge de la arteria subclavia. El presente informe describe un origen anómalo de la arteria vertebral izquierda (LVA) desde el arco aórtico entre el origen de la subclavia izquierda y la arteria carótida común izquierda. Esta arteria cruzó superficialmente de medial a lateral el tronco simpático izquierdo. La VA izquierda y derecha entraban en los agujeros transversos de la quinta vértebra cervical. Aunque el origen anómalo de la VA es bien conocida, su origen y la entrada a través del foramen transversal y sus relaciones con tronco simpático son de importancia clínica y durante los procedimientos vasculares en la región de cabeza y cuello tales como los stent de arteria carótida o vertebral y las intervenciones intracraneales. Variations of major arterial vessels are of clinical significance. The vertebral artery (VA) normally arises from the subclavian artery. The present report describes an anomalous origin of the left vertebral artery (LVA) from the aortic arch between the origin of the left subclavian and the left common carotid arteries. This artery was crossed superficially from medial to lateral by the left sympathetic trunk. The left and right VA entered the foramen on the transverse process of the fifth cervical vertebra. Though the anomalous origin of the VA is known, its origin and entry through the transverse foramen and its relations with sympathetic trunk are of importance during clinical and vascular procedures in the head and neck region like carotid artery stents, VA stents and intracranial interventions.

“…Right vertebral artery was seen a direct branch from the arch of aorta between left common carotid artery and left subclavian artery by Sait Albayram et al [18], M. Loukas et al [25], it was seen as last branch of aortic arch distal to left subclavian artery by P. Ligege et al [3] and as a branch right common carotid artery by Young-Don Kim et al [21] and Ronald A. Bergman et al [22]. However no such variation was found in the present study.…”

Objectives: An understanding of anatomy is essential to surgeons and knowledge of variations is of practical importance. The anatomic and morphologic variations of great vessels are significant for diagnostic and surgical procedures in the neck and thorax region. Vertebral artery is a branch of subclavian artery, generally arising from the first part of subclavian artery on both the sides. Multiple variations in the origin of vertebral artery have been reported in the literature, most common being directly from the arch of aorta, as a branch of thyrocervical trunk, as a branch of common carotid or external carotid artery.
