Abstract
|
|
|
|
We report two cases of the aberrant vertebral artery, which originated from the part of the aortic arch about 2.5 cm distal to the left of the subclavian artery origin. The aberrant vertebral arteries were relatively hypoplastic. Herein, we review the previous reported cases in the literature and discuss embryologic basis and clinical implication of this variation.
