A member asked:
What exactly does it mean to have an anomalous origin to the right subclavian artery, arising from distal aortic arch?
3 doctors weighed in across 2 answers
Anatomy: Although i can define this for you, I am unaware of the clinical implications. There are three main arteries which project from the aortic arch -- the brachiocephalic trunk (which splits to form the right subclavian artery and right common carotid); left common carotid; and left subclavian. Anomalous origin means that the artery is arising from an anatomically unusual location.

Anatomy: In the picture you see the aortic arch and the 3 vessels coming off. These are the innominate, left carotid and left subclavian. The proximal aorta is coming from your heart and the distal aorta is heading away to your body. Usually the right subclavian would come off the innominate. Yours, probably due to a developmental quirk, comes distal directly off the aorta.
