Surgical retrieval of an embolized central venous catheter in a premature baby.

Embolization of central venous catheter fragments is usually treated with percutaneous interventional techniques, which are difficult to apply in infants with very low birth weight. We surgically removed a catheter fragment in a preterm neonate, to avoid the impending thrombosis of the right pulmonary artery. The operation was performed with a nerve hook introduced through a tiny incision in the vessel's wall. The procedure was well tolerated, and no stricture remains at the site of incision.
