Right subclavian artery anomalies

Last reviewed dd mmm yyyy. Last edited dd mmm yyyy

Rarely, the right subclavian artery arises from the aortic arch distal to the left subclavian artery. To reach the right side of the thorax, it passes behind the oeosphagus and trachea to produce a vascular ring.

Developmentally, this condition results from regression of the right fourth branchial arch artery.
