Left mediastinal central line malposition--a case report.

Central venous line malpositioning in the left mediastinum is a rare event. A case of left superior intercostal vein central venous line placement is reported. Chest radiographs, especially lateral views and contrast studies, are useful for position evaluation. Catheter removal is prudent although the purpose of the catheter and the symptomatology can dictate further management of the malpositioned catheter.
