Complete isolation of right subclavian artery supplied by the thoracic aorta and bilateral patent ductus arteriosus

Disconnection of the subclavian artery from the aortic arch, defined as isolation, is a rare aortic arch anomaly. In this anomaly, loss of continuity between one subclavian artery and the aorta with persistent connection to the homocollateral pulmonary artery through a patent or remnant ductus arteriosus is present. This isolation is almost always seen on the side contralateral to the aortic arch position. Complex cardiac and genetic anomalies are frequently associated with the isolation of a subclavian artery. We report a rare case of right subclavian artery originating from right pulmonary artery with bilateral patent ductus arteriosus in an otherwise normal infant.
