I Left Vertebral Artery with a Proximal Stenotic Origin and Clinical Implications

Even though most vertebral artery anomalies are asymptomatic, but the normally arising from superoposterior surface of its ipsilateral subclavian artery, plays a vital role, via Subclavian Steal Syndrome to help in vascularization upper limb anatomical structures.
