Abstract

Patent ductus arteriosus (PDA) is prevalent in premature newborns and has been linked to the development of bronchopulmonary dysplasia (BPD), a serious pulmonary complication of premature birth. Although a causal relationship has not been proven, the link is greatest among infants born at lower gestational age who are treated with mechanical ventilation in the presence of a large ductal shunt. Despite strong association in epidemiological studies, treatment of a patent ductus arteriosus has not been shown to prevent BPD, and some therapies may increase the risk of BPD. We describe preclinical and clinical data demonstrating the association of a PDA with BPD, highlight the effects of surgical and pharmacological treatment, and explore the implications of recent clinical trials for the management of PDA in the premature newborn.
