Abstract

We present a pictorial review of anomalous origin of the left vertebral artery observed in 5 patients imaged in our after-hours trauma radiology unit within a period of 7 days. We raise the question of whether the incidence of anomalous origin of the left vertebral artery quoted in the radiology literature as 5% is really that low, and suggest that the current increased frequency of cross-sectional imaging could elevate the observed incidence of this anomaly in practice. We discuss the implications of vertebral artery anomalies in the endovascular treatment of aortic arch injuries.
