Summary

The alpha maneuver effectively repositions displaced peritoneal dialysis catheters, resolving drainage issues in many patients. This bedside technique should be the first choice before considering invasive interventions for catheter malfunction.

Area of Science:

  • Nephrology
  • Gastroenterology
  • Surgical Procedures

Background:

  • Peritoneal catheter tip displacement frequently causes malfunction, impeding peritoneal dialysis (PD) effluent drainage.
  • Traditional solutions like catheter exchange or invasive surgery are often required.
  • The alpha maneuver offers a less invasive alternative for correcting catheter tip displacement.

Purpose of the Study:

  • To review the clinical experience and effectiveness of the alpha maneuver in treating displaced peritoneal dialysis catheters.
  • To evaluate the alpha maneuver as a first-line treatment option for PD catheter malfunction due to displacement.

Main Methods:

  • Retrospective review of 24 peritoneal dialysis patients who underwent the alpha maneuver for catheter tip displacement.
  • Total of 32 procedures were performed, with some patients requiring repeat interventions.

Related Experiment Videos

  • Radiologic examination confirmed catheter tip displacement in all cases prior to the maneuver.

    • Main Results:

    • The alpha maneuver was initially effective in 46% (11 of 24) of patients.
    • Repeat procedures were necessary in 6 patients, with an overall success rate of 79.2% (23 of 24) when considering repeat attempts and excluding omentum entrapment.
    • Unsuccessful maneuvers were more common within the first 3 months of catheter placement (84% of failures).

    Conclusions:

    • The alpha maneuver is a simple, effective bedside procedure for displaced peritoneal dialysis catheters, reducing the need for invasive interventions.
    • It should be considered the primary treatment of choice for catheter tip displacement.
    • Invasive methods, such as catheter exchange, should be reserved for cases where the alpha maneuver proves unsuccessful.
