Patent ductus arteriosus: From pharmacology to surgery

摘要

Patent ductus arteriosus (PDA) may be found in 0.1-0.2 of term infants, but the average incidence is at least five-fold higher in premature infants, correlating inversely with birth weight and gestational age. While not all patients with a PDA require treatment, the deleterious effects of persistent left-to-right shunting across the ductus can have important short-and long-term consequences. Medical and inter-ventional approaches to PDA closure have evolved greatly in the past decade and add to the decision-making pathways. This article summarizes the pathophysiology of PDA and characterizes the medical, surgical and endovascular treatment approaches. (c) 2021 Elsevier Inc. All rights reserved.
