Abstract
Anomalous origin of the right vertebral artery from the right common carotid artery (VA-CCA) with an aberrant right subclavian artery (ARSCA) is an uncommon anatomical variant. We present a series of images from a case in which this was identified on angiography for the management of a right posterior inferior cerebellar artery (PICA) aneurysm. This combination has not been previously described in the literature. The embryological mechanism of this variation, the incidence of these individual findings and the clinical implications will be discussed.
