These cases include a left vertebral artery as the 2nd branch off the left subclavian, a left vertebral artery with 2 origins, a right vertebral artery arising as the last branch off the aorta, a right vertebral artery arising as the 2nd branch off the right subclavian artery, and right vertebral artery with proximal duplication as the 2nd branch off the right subclavian artery.}, issn = {0195-6108}, URL = {https://www.ajnr.org/content/28/5/976}, eprint = {https://www.ajnr.org/content/28/5/976.full.pdf}, journal = {American Journal of Neuroradiology} }
