title: Crisscross pulmonary artery with double aortic arch: an unusual association.
abstract: Anomalies of pulmonary artery origin are rare. Crisscross pulmonary artery origin is a rare benign anomaly characterized by the left pulmonary artery arising superiorly and to the right side of the right pulmonary artery. The condition is usually accompanied by a conotruncal anomaly. Here, we report a child with crisscross pulmonary arteries and a complete vascular ring formed by a double aortic arch, which was confirmed by computed tomography angiography. The child underwent surgical correction for relief of stridor.
