Reexpansion pulmonary edema (RPE) is rare and usually follows rapid reexpansion of a collapsed lung. We report on a preterm infant who developed pulmonary edema within an hour of surgical ligation of patent ductus arteriosus (PDA). There were no other cardiac anomalies, fluid overload or airway obstruction to explain the change in clinical status. With supportive treatment the patient's condition became stable and was extubated within 48 hours. Lung retraction for better field exposure is often needed when performing PDA ligation in preterm infants. Reinflation of a retracted lung is thought to be the cause of our patient's pulmonary edema. We conclude that RPE, although uncommon, may occur following surgical ductal ligation and that clinicians should be aware of such a possible complication.
