Variability of the origin of the major arteries
from the aortic arch, Arcus aortae.
a
“Textbook case”
b Common origin of the brachiocephalic trunk and the left
common carotid artery
c
Common trunk for the brachiocephalic trunk and the left
common carotid artery
d Left vertebral artery branching off the aortic arch
independently
e Right subclavian artery as the ultimate branch of the
aortic arch
This abnormal artery frequently passes behind the
oesophagus to the right, which can result in swallowing
difficulties (Dysphagia lusoria).
