Central venous access for long-term haemodialysis

Area of Science:

• Nephrology
• Vascular Surgery
• Internal Medicine

Background:

• Chronic dialysis necessitates reliable vascular access.
• Severe access difficulties pose significant challenges for patients requiring renal replacement therapy.
• Conventional vascular access methods and alternative therapies may repeatedly fail.

Purpose of the Study:

• To evaluate the efficacy and safety of long-term central venous catheterization as the sole vascular access method.
• To assess the feasibility of permanent indwelling central venous catheters in patients with complex access issues.

Main Methods:

• Nine chronic dialysis patients with severe access difficulties were included.
• Catheters were inserted into the right atrium via jugular veins using a simple operative technique.
• Catheters remained in situ for 1-33 months.

Main Results:

• No patient failed the technique, demonstrating its reliability.
• Catheter-related complications were infrequent.
• Three catheters required replacement due to incorrect positioning (2 patients) and thrombosis (1 patient).

Conclusions:

• Long-term central venous catheterization is a viable option for chronic dialysis patients with intractable vascular access problems.
• This method enables adequate and safe hemodialysis when other options have failed.
• Permanent indwelling central venous catheters can be a successful sole method of vascular access.
