Patient Data

Age: 35 years
Gender: Female

Known aberrant right right subclavian artery arising as a 4th branch from the aortic arch with retro-esophageal course. The right subclavian artery, right axillary and right brachial artery are patent. The right vertebral artery arises from the right common carotid artery.

Case Discussion

It is uncommon for the vertebral artery to arise from the anterior circulation, where it may arise from the CCA, ICA or ECA. As is common, this patient has several other vascular anatomic variants.
