Truncus arteriosus repair after palliative bilateral pulmonary artery banding.

A 3.5-month-old girl was diagnosed with type I truncus arteriosus and severe pulmonary hypertension. We performed palliative bilateral pulmonary artery banding (right and left circumferences, 14 and 12 mm, respectively). Corrective repair for truncus arteriosus was then performed at 10 months of age. The good postoperative course in this patient demonstrates that palliative bilateral pulmonary artery banding is a useful surgical option for truncus arteriosus associated with pulmonary hypertension.
