An anomalous collateral artery was found during the dissection for the pectoralis major myocutaneous flap procedure. This anomalous collateral artery was stemming from the left internal thoracic artery. It is believed that this collateral was formed secondary to congenital aortic coarctation causing abnormal growth of the left fourth aortic arch. This is the first reported case of such a collateral artery in recent literature.
