Patent Ductus Arteriosus in Premature Infants

Abstract
Patent ductus arteriosus (PDA) developed in 17 of 111 premature infants (birth weight 1750 g or less) born during a four-year period (15.3 per cent incidence). During that time we treated 29 such infants, 17 born at our own institution and 12 similar infants transferred from other hospitals. Sixteen of the 29 had cardiac catheterization, 10 had operative closure of the PDA, and 24 survived.
