Percutaneous closure of a large iatrogenic fistula between the inferior vena cava and the pulmonary vein in a child.

We hereby describe a complex late postoperative veno-venous fistula in a child, successfully treated by an interventional percutaneous procedure. It is a unique complication of diaphragmatic hernia surgery that has never been reported before: a late postoperative iatrogenic fistula, between the inferior vena cava and the right lower pulmonary vein, discovered in a 6-year-old boy operated at the age of 4 months for a right diaphragmatic hernia. The right to left shunt was completely and uneventfully suppressed by a percutaneous procedure separating the systemic venous return from the pulmonary venous return with an Amplatzer Vascular Plug II.
