Truncus Arteriosus With Major Aortopulmonary Collateral Arteries.

Truncus arteriosus with the absence of one branching pulmonary artery and presence of major aortopulmonary collateral arteries is rare. A small patient, with a birth weight of 2,219 g, was successfully repaired by a staged approach, after banding of the left pulmonary artery and unifocalization of major aortopulmonary collateral arteries.
