Complications associated with indwelling venous Hickman catheters in patients with hematological disorders.

During a 28 month period, 77 Hickman catheters were inserted in 66 patients with hematological disorders. Complete follow-up was possible for 72 catheter insertions. Catheters remained in situ for a median period of 77 days (range 5-474 days). Fourteen (19%) catheters required removal because of complications which included sepsis, blockage, or displacement. Catheter-related infection was the major complication and Staphylococcus epidermidis and diphtheroids (Corynebacterium species) were the organisms most commonly isolated.
