PY - 2011 T2 - Rudolph's Pediatrics, 22e AB - During fetal life, the ductus arteriosus diverts blood away from the fluid-filled lungs toward the descending aorta and placenta. In full-term infants, obliteration of the ductus arteriosus takes place after birth through a process of vasoconstriction and anatomic remodeling. Premature infants frequently fail to close their ductus arteriosus. The clinical consequences of a patent ductus arteriosus (PDA) are related to the degree of left-to-right shunt through the PDA with its associated change in blood flow to the lungs, kidneys, and intestine.
