The swan neck presternal catheter offers a lower infection risk and better patient outcomes compared to abdominal catheters. It is ideal for specific patient groups, improving quality of life during dialysis.

Area of Science:

  • Nephrology
  • Medical Devices
  • Surgical Innovation

Background:

  • Peritoneal dialysis catheters with abdominal exits are prone to infections.
  • The swan neck presternal catheter was developed to mitigate exit site infections.

Purpose of the Study:

  • To evaluate the performance and safety of the swan neck presternal catheter.
  • To compare its outcomes with traditional abdominal peritoneal dialysis catheters.

Main Methods:

  • Analysis of data from 974 worldwide swan neck presternal catheter implantations (1991-2001).
  • Detailed follow-up of 150 presternal catheters at the University of Missouri for over 130 patient-years.

Main Results:

  • Presternal catheters demonstrated superior performance regarding exit and tunnel infections.

  • The two-year survival probability was 0.95, with recurrent peritonitis being the sole failure cause.
  • Beneficial for obese patients, those with ostomies, children, and patients desiring baths.

    • Conclusions:

    • The swan neck presternal catheter is a safe and effective alternative, especially for challenging patient populations.
    • It offers improved infection control and patient satisfaction compared to abdominal exit sites.
    • While implantation is more complex, clinical benefits outweigh the minor drawbacks.
