[Temporary and permanent central venous catheters for hemodialysis].

The usage of temporary and permanent dialysis catheters for hemodialysis vascular access has been on continual increase. The reason for this increase is aging population on hemodialysis with blood vessels inappropriate for arteriovenous fistula creation. Complications may occur during catheter insertion as well as in the already inserted catheters, e.g., thrombosis and infections. The severity of complications is determined by experience of the operator as well as the quality and localization of blood vessels. Monitoring of dialysis catheter function, choice of the site of catheter insertion and methods of salvaging catheters from thrombosis and treating catheter-related local and systemic infections are described in this paper. Constant evaluation, proper care and hygiene of dialysis catheters are highly recommended.
