Recently, varying number of aberrantVA types has been reported; extraordinarily, in our case, both VAs have derived directly from the aortic arch at whichdistal to the origin of the left subclavian artery (LSA). In our case, the fourth branch of the aortic arch was the left VAand the fifth branch was the right VA. To the best of our knowledge, this is the second report in the literature showingan abnormal origin of both the right and left VAs originating distal to the origin of the LSA. We have presented here anextremely rare case of aberrant right and left VAs in one patient.info:eu-repo/semantics/openAccessAberrantAortic ArchBilateralVertebral ArteryPresentation31707210.14744/ejmo.2018.0003
