Percutaneous insertion of subclavian Hickman catheters

We have assessed the percutaneous insertion of Hickman catheters implanted directly into the subclavian vein; 116 catheters were inserted in 86 patients. The catheters were all inserted by members of the haematology staff. The majority of the catheters were inserted under local anaesthetic in a haematology ward with filtered positive pressure ventilation. X-ray screening was not routinely used. The average patient age was 45 years and the average platelet count was 155 x 10(9)/l. Sixty-seven per cent of the catheters either remain in situ or have been removed electively or at death. The remainder have been removed for a variety of reasons (infection 10%, suspected infection 8%, accidental dislodgement 7%, thrombosis 4%, catheter blockage 3%, catheter fracture 0.9%). The only complication specific to direct subclavian puncture was pneumothorax (4%). This disadvantage may be offset by rapid insertion, a cosmetically superior result and the avoidance of surgical and operating theatre time.
