Variant origin of the left vertebral artery from a vertebro-subclavian trunk associated with an unusual branch arising from the brachiocephalic trunk.

Variant origin of the left vertebral artery (LVA) from the arch of aorta is well documented in the literature. Involvement of complex sequential developmental steps in the aortic arch formation results in different patterns of origin of LVA. Morphological variations in the LVA are thought to alter t...
