There are multiple reports in the literature of vascular erosion in the innominate vein or superior vena cava from the use of temporary central venous catheters. Catheter malposition is likely to precede the development of superior vena cava perforations, a catastrophic complication of central venous catheters. Catheter malposition after initial adequate placement is a very unusual long-term complication and delayed recognition of this complication may have disastrous consequences. ⋯ We report three patients with left-sided long-term indwelling Silastic catheters that had changed position over time who presented with chest pain upon infusion of their total parenteral nutrition solutions. In each case, chest x-ray revealed that the tip of the catheter had migrated and was directed against the sidewall of the superior vena cava. In each case, catheter removal and replacement with a new catheter into the right side (subclavian and jugular systems) led to prompt relief of the patient's symptoms.
