Objective(s): Left mainstem bronchial compression by a midline descending thoracic aorta is a rare anatomic variant. Translocation of the descending thoracic aorta to the ascending aorta has recently been described to treat this condition.
Methods: We performed an aortic translocation and right pulmonary artery reimplantation in a 4-month old infant with recurrent respiratory infections and suprasystemic pulmonary artery pressure.
Results: The procedure was initially successful in relieving the left bronchial compression and opening the orifice to the right pulmonary artery. Distal hypoplasia of the diminuitive right pulmonary artery was then accomplished as a staged procedure 6 months later.
Conclusions: This is the smallest and youngest patient reported to have undergone descending aortic translocation to treat life-threatening left bronchial compression.
