Bilateral Aberrant Vertebral Arteries: An Extraordinary Case
Vertebral arteries (VAs) arise as the first branch of the ipsilateral subclavian artery. Recently, varying number of aberrant VA types has been reported; extraordinarily, in our case, both VAs have derived directly from the aortic arch at which distal to the origin of the left subclavian artery (LSA). In our case, the fourth branch of the aortic arch was the left VA and the fifth branch was the right VA. To the best of our knowledge, this is the second report in the literature showing an abnormal origin of both the right and left VAs originating distal to the origin of the LSA. We have presented here an extremely rare case of aberrant right and left VAs in one patient. Keywords: Aberrant, aortic arch, bilateral, vertebral artery
