Migration of a central venous catheter into pulmonary vein complicated with lung edema in a premature infant.

In this paper, we present a preterm infant with acute focal lung edema due to central venous catheter migration into the right pulmonary vein. The substances aspirated from the endotracheal tube contained the parenteral nutrition fluid. Thus, parenteral nutrition fluid extravasation into the lung or a vasculopulmonary fistula was suspected. The course of complication was smooth after the catheter was withdrawn into the right atrium. This unusual presentation during TPN hyperalimentation was described in order to prevent a potentially dangerous event.
