Abstract :
Three major arteries normally originate from the aortic arch. Variations of the aortic arch
branches are observed in some cases. Rare variation of the aortic arch branches is originated
from the retroesophageal right subclavian (RRS) artery as the last branch of the aortic arch.
Variation of artery is possibly associated with the variation of the recurrent laryngeal nerve.
This research provides an in vivo report of retroesophageal right subclavian artery during
examination of the cervical vessels using magnetic resonance angiography (MRA). It is very
important to consider the variation of the right subclavian artery during head and neck surgery.
Non-invasive techniques such as MRA of cervical arteries can be used in order to examine
them.
