CTICasesSurgically repaired proximal interruption of the right pulmonary artery
Imaging findings
Initial CT of an infant shows interruption of the right pulmonary artery with systemic collateral supply. Postoperative CT shows successful surgical reconstruction of the right pulmonary artery using a conduit and ligation of the right-sided ductal remnant.
Key takeaways
Early diagnosis of pulmonary artery interruption allows surgical reconstruction. Re-establishing connection between the main PA and the distal pulmonary arterial bed preserves lung function and prevents development of severe pulmonary hypertension.
