Bronchus compression relieved by patent ductus arteriosus stenting.

Background: Patent ductus arteriosus (PDA) stenting is evolving as an alternative to surgical aorto-pulmonary shunts for infants with ductal-dependent pulmonary blood flow. Given anatomical proximity, the PDA can compress the ipsilateral bronchus. We report a case series of four patients with bronchial compression by a tortuous PDA who underwent PDA stenting.
