There is a higher incidence of delayed closure of the patent ductus arteriosus in premature babies with respiratory distress syndrome. From July, 1975, to December, 1977, 57 small, preterm infants with patent ductus arteriosus were diagnosed at our neonatal intensive care unit. From July, 1975, until September, 1976 (first period), 23 patients were diagnosed, and 11 underwent surgical ligation of a patent ductus arteriosus. There were 3 early deaths. From October, 1976, until December, 1977, out of a total of 34 patients with diagnosed patent ductus, 18 were treated with indomethacin, and only 3 required ligation. Our present policy for patent ductus arteriosus with respiratory distress syndrome in the premature baby is to initiate early treatment with indomethacin. If this treatment fails and the infant's status deteriorates, we perform early surgical ligation of the ductus in order to minimize the time on mechanical ventilation and lessen the chances of the development of bronchopulmonary dysplasia. © 1980, The Society of Thoracic Surgeons.
