Systemic to Pulmonary Collaterals in Very Low Birth Weight Infants: Color Doppler Detection of Systemic to Pulmonary Connections During Neonatal and Early Infancy Period

Abstract

The incidence of SPC in VLBW infants is much higher than previously reported. We postulate that SPC are bronchopulmonary communications that enlarge and/or proliferate in response to a given stimulus. These communications are associated with increased time on positive pressure ventilation and length of stay in the hospital. SPC may lead to pulmonary edema and should be searched for in VLBW infants with a more complicated course. Echocardiographic examination with color Doppler performed in premature infants to evaluate left to right shunts should include careful search for systemic to pulmonary collaterals.echocardiography, systemic to pulmonary collaterals, aortopulmonary collaterals, prematurity, pulmonary edema.
