Abstract
Systemic-to-pulmonary collaterals
(SPCs) occur in a variety of pathologic conditions, including congenital heart
diseases, chronic pulmonary infections, lung tumors, pulmonary emboli, and
bronchopulmonary dysplasia. Systemic-to-pulmonary collaterals can also occur in
premature infants without cardiac or lung disease; such collateral vessels
appear to be transient. Occasionally, SPCs result in left-to-right shunts that
warrant intervention. We describe the case of a preterm infant whom we weaned
from chronic supplemental oxygen after coil embolization of 2 persistent SPCs.
