Right pneumonectomy syndrome: a lethal complication of lung resection in a newborn with cystic adenomatoid malformation.

A newborn girl underwent a right pneumonectomy for cystic adenomatoid malformation. She subsequently developed compression of the trachea and left mainstem bronchus by a combination of aortic arch, pulmonary artery, and ductus arteriosus. She died while planning aortic suspension, and the anatomic relationships were confirmed by autopsy. This problem is potentially treatable by a variety of means.
