The insertion of chronic indwelling central venous catheters (Hickman lines) in interventional radiology suites.
The insertion of Hickman central venous catheters for chronic venous access is a procedure usually conducted in the operating theatre under local or general anaesthesia. In a prospective study over a one year period we have assessed the feasibility of radiologists inserting central venous catheters for long term access. A subclavicular approach to the subclavian vein with prior digital subtraction angiography or video imaging of the vein was the technique of choice. Thirty-one Hickman catheters were inserted in 21 patients. All but two patients had a haematological malignancy. Ages ranged from 19 to 77 years. The mean time for insertion was 43 min (range 20-80 min). The catheters remained in situ for between 2 days and 242 days with a mean of 86 days. There was one documented line infection; nine patients had episodes of septicaemia with identified organisms, and a further six had pyrexias of unknown origin during the line indwelling period. There were four documented line and or ipsilateral subclavian vein thromboses, and one death occurred within 36 hours of the procedure. We conclude that radiological placement is an excellent alternative to 'blind' surgical placement. Screening during insertion provides immediate facilities for correction of malposition and monitoring of immediate complications. The time taken for catheter insertion did not impede the usual patient throughout in the interventional radiology suite.
