Area of Science:

  • Interventional Cardiology
  • Pediatric Vascular Access
  • Medical Device Technology

Background:

  • Central vascular access can be challenging in infants, especially with altered anatomy.
  • Existing central catheters may offer opportunities for novel access techniques.

Purpose of the Study:

  • To describe and evaluate a new technique for establishing additional vascular access in infants using an existing central catheter.
  • To assess the safety and efficacy of snare-assisted vascular access placement.

Main Methods:

  • A 4 Fr end hole catheter was advanced under fluoroscopic guidance.
  • An Amplatz snare catheter was used through the existing catheter to guide a wire.
  • Percutaneous placement of a new catheter over the guidewire was performed.

Main Results:

  • The technique was successfully utilized 16 times in 13 patients.
  • No complications were reported, indicating a safe procedure.
  • Reliable additional vascular access was achieved.

Conclusions:

  • Snare assistance is a safe and effective method for establishing additional vascular access.
  • This technique provides a reliable solution for challenging infant vascular access scenarios.
  • Fluoroscopic guidance and specialized catheters facilitate successful outcomes.
