Anomalous origin of one pulmonary artery from the innominate artery: A report of two cases

Two children with an anomalous origin of one pulmonary artery from the inno minate artery are reported. One was a 15-month-old boy presenting with resp iratory distress. He had a right aortic arch and his left pulmonary artery originated from the innominate artery. The other was a 1-month-old girl pre senting with congestive heart failure. She had a left aortic arch and her r ight pulmonary artery originated from the innominate artery. An understandi ng of the embryological pathogenesis of these anomalies has significant the rapeutic implications.
