“…Lack of flow in the right subclavian artery proximal to the right vertebral artery origin may result in shunting and retrograde flow of blood or “steal” to the distal right subclavian artery via collaterals including the right vertebral artery. In people, caroticovertebral shunting via the Circle of Willis occurs and may present clinically as “steal” in the form of transient cerebral ischemia during arm use 11,13 …”

A 3-year-old dog with cervical myelopathy resulting from a vascular anomaly is described. Marked intradural-extramedullary spinal cord compression was observed, in association with multilevel ectatic anastomotic radicular arterial branches connecting the left and right vertebral arteries. A nonpatent proximal segment of the right subclavian artery had resulted in compensatory enlargement of the left vertebral artery. Flow within the right vertebral artery was retrograde and fed into the patent distal segment of the right subclavian artery. Multiple imaging techniques including myelography, computed tomography, magnetic resonance imaging, and selective digital angiography were used to document this anomaly. To reduce spinal cord compression the largest collateral vessel was embolized without complication. Good clinical response was observed within 6 weeks and improved clinical neurologic function was maintained at the time of a 12-month re-evaluation.

“…This reversal of blood flow in the vertebral artery can result in hypoperfusion to the ipsilateral posterior brain, causing vertebrobasilar symptoms such as vertigo, diplopia and presyncope. In 1986, authors Vleeschauwer, Horsch and Koln were the first to report on a case of right SSS as the result of an ARSA [ 6 ].…”

Aberrant right subclavian artery (ARSA) is a rare congenital malformation, wherein the aorta gives rise to the right subclavian artery as a branch off the aortic arch distal to the takeoff of the left subclavian artery. We presented a case of a patient with ARSA that manifested vertebrobasilar symptoms. PubMed search was preformed using keywords ‘aberrant right subclavian artery’, ‘right subclavian steal’ and ‘vertebrobasilar’, which generated nine articles. We found only seven case reports through a PubMed search that discuss ARSA in association with Subclavian steal syndrome. Approximately 71% (n = 5) of the patients in our literature review manifested with signs and symptoms of vertebrobasilar insufficiency. Given the complex anatomy in this condition, treatment should be aimed at symptom resolution. Carotid-subclavian bypass ultimately resolved the symptoms in our patient. Management in symptomatic patient is surgical. In addition to open technique, endovascular interventions can be an option.

“…The transposition of the subclavio-carotid artery is particularly justified if there is a proximal stenosis of the subclavian artery, the existence of embolism pathology of the upper limb, the need to revascularize at best a vertebral artery in the presence of vertebrobasilar ischemia. It is a safe technique with low reocclusion rates [6], and an actuarial permeability ranging from 95 to 100% for mean follow-ups beyond 50 months [7], it is the technique of choice for treating subclavian flight due to an aberrant right subclavian artery [8]. The last method is represented by the carotido-sub clavian bypass.…”
