Bronchial compression by dilated pulmonary artery. Surgical treatment.

Bronchial compression by a dilated left pulmonary artery complicated the postoperative course in two infants: one after a Mustard operation for transposition of the great arteries, restrictive ventricular septal defect, and moderate pulmonary stenosis, the second after correction of tetralogy of Fallot with absent pulmonary valve. In both cases the bronchial compression was successfully treated by division of the left pulmonary artery and its prolongation by interposition of a conduit.
