Palliative vertical vein stenting in a critical neonate with obstructed infradiaphragmatic total anomalous pulmonary venous connection.

Neonatal total anomalous pulmonary venous connection has an incidence of about ∼1-2%.1 The clinical presentation of total anomalous pulmonary venous connection in the neonatal period is dependent on the presence or absence of pulmonary venous obstruction, which is usual when the veins connect to the umbilicovitelline system, as in infradiaphragmatic total anomalous pulmonary venous connection. Obstructed total anomalous pulmonary venous connection presents with severe respiratory distress, metabolic acidosis, and cyanosis and requires urgent surgical intervention.
