A novel alpha replacement method effectively displaces Swan neck straight (SNS) catheters into the minor pelvic space. This minimally invasive technique was successful in all patients with no complications, offering a promising advancement in catheter management.

Area of Science:

  • Medical Devices
  • Surgical Techniques
  • Interventional Radiology

Background:

  • Catheter displacement is a critical step in various medical procedures.
  • Existing methods for Swan neck straight (SNS) catheter manipulation can be challenging.
  • A need exists for a safe, efficient, and minimally invasive technique for SNS catheter repositioning.

Purpose of the Study:

  • To introduce and evaluate a novel method for displacing the Swan neck straight (SNS) catheter.
  • To assess the efficacy, safety, and procedural time of the new 'alpha replacement method'.

Main Methods:

  • Development of the 'alpha replacement method' utilizing a 1.5 mm flexible metal guide wire.
  • The guide wire is inserted through the catheter's transfer tube to the mesenterium, forming a loop.

  • Gentle pressure on the guide wire facilitates catheter movement into the minor pelvic space; removal is achieved by pressing on the lower abdomen.

    • Main Results:

    • The alpha replacement method achieved successful catheter displacement in all 8 patients.
    • The average manipulation time for the procedure was approximately 15 minutes.
    • No intraoperative or postoperative complications were reported in any of the patients.

    Conclusions:

    • The alpha replacement method is a safe and effective technique for SNS catheter displacement.
    • This novel procedure offers a reduced manipulation time and a complication-free outcome.
    • The alpha replacement method represents a significant advancement in minimally invasive catheter management.
