Abstract
This report describes a case of duplicated origin of the right vertebral artery incidentally found in a young patient. Computed tomographic angiography and digital subtraction angiography showed a dominant branch derived from the right common carotid artery and an accessory branch that derived from the right subclavian artery, which aberrantly originated from the far left aortic arch, and adjoined the dominant branch at the C5 level. We discuss angiographic findings, clinical implications and embryological basis for this rare anomaly.
