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.
