Repair of infracardiac total anomalous pulmonary venous connection in a 902-gram infant with asplenia syndrome after failed umbilical venous catheter intervention

Abstract

Ductus venosus stenting via a transumbilical approach for pulmonary venous obstruction in infracardiac total anomalous pulmonary venous connection has been described. In a 902-gram infant who was diagnosed with asplenia syndrome and infracardiac total anomalous pulmonary venous connection, ductus venosus stenting was attempted by a transumbilical approach. However, ductus venosus stenting was discontinued due to bleeding from the portal vein. The bleeding subsided in time spontaneously, and total anomalous pulmonary venous connection repair with pulmonary artery banding was performed on 21 days after birth. To our knowledge, this is the first report that describes total anomalous pulmonary venous connection repair in a neonate under 1000 g body weight. Learning objectiveDuctus venosus stenting is an effective palliative option, especially in the presence of high surgical risk, such as heterotaxy syndrome and a low birth weight. However, ductus venosus stenting should carefully be evaluated by assessment of anatomical configuration of umbilical vein and ductus venosus. If ductus venosus stenting is anatomically difficult, primary surgical repair may be an option even in an extremely low birth weight infant.
