Anomalous origin of innominate artery from right pulmonary artery in DiGeorge syndrome

We experienced a case of anomalous origin of innominate artery from right pulmonary artery (isolated innominate artery). This patient was a 2-month-old baby girl weighing 3.2 kg with DiGeorge syndrome, who was diagnosed with perimembranous ventricular septal defect, atrial septal defect, and patent ductus arteriosus. This type of anomaly is exceedingly rare.
