Abstract
In a series of 60 consecutive patients in whom Hickman catheters were placed for treatment of malignancy, four properly positioned catheter tips migrated secondarily from the superior vena cava to the ipsilateral jugular vein 2, 4, 21, and 25 days after placement. Three of the four patients had begun to have catheter dysfunction when the displacement was diagnosed. No satisfactory explanation for this rarely reported complication was evident in three of the cases. Maneuvers such as coughing, Valsalva's maneuver, and forceful heparin flushing produced no motion in three normally directed catheter tips in other patients observed under fluoroscopy. The phenomenon may be more common than previously reported. Evaluation of any new Hickman catheter dysfunction should include a chest x-ray film to ascertain the position of the catheter.
