Translumbar inferior vena cava cannulation.

Abstract

Background: The aim of the study was to review our three year experience with translumbar insertion of dialysis catheters.

Methods: In five adult patients (4 males and one female, mean age 45 yr), requiring dialysis due to end-stage chronic renal failure, the inferior vena cava was cannulated because of the impossibility of using any other approach. All procedures were performed under fluoroscopy. After visualisation of the inferior vena cava by injection of contrast medium into a peripheral vein, the vena cava was punctured with a 20 cm long needle, at the L3 level. The position of the needle was confirmed by injection of contrast medium, and the vein was then cannulated with a peel-away cannula, using a standard Seldinger technique. Subsequently, a pre-tunneled silastic catheter was introduced and secured.

Results: The catheters were used for from 3 to 10 months. No case of permanent catheter dysfunction was noted. Three episodes of temporary thrombosis, in two patients, were successfully treated with heparin and urokinase. Three catheters became contaminated, but they were treated without the necessity for catheter removal.

Conclusion: The described method is a safe and effective way of securing haemodialysis access in patients where a standard approach is not possible.
