title: Bronchial obstruction secondary to aneurysm of a persistent ductus arteriosus.
abstract: A 4-month-old infant presented with aneurysm of patent ductus arteriosus (PDA) which was causing obstruction of the left main bronchus. The patient had elevated pulmonary vascular resistance (PVR) at 6.1 um2. The aneurysm was resected on cardiopulmonary bypass. The patient required phenoxybenzamine and prostacycline after the operation for elevated PVR. Postoperative progress was prolonged but 12 months after surgery the patient is well, growing normally without any respiratory symptoms.
