Area of Science:

  • Vascular surgery
  • Interventional radiology
  • Medical device engineering

Background:

  • Centrally located intravascular foreign bodies pose significant clinical challenges.
  • Percutaneous retrieval is the preferred method for managing these emboli.
  • Existing techniques may be limited in mobilizing fixed foreign bodies.

Observation:

  • A novel technique was developed for percutaneous removal of intravascular foreign bodies.
  • The technique utilizes bilateral femoral vein puncture for catheter insertion.
  • A curved-end catheter and a Dormia basket catheter system are employed.

Findings:

  • The technique effectively mobilizes fixed foreign bodies into an accessible position.
  • A wire is passed through the first catheter and grasped by the Dormia basket.

Related Experiment Videos

  • Traction on both catheter systems facilitates foreign body mobilization and subsequent removal.

    • Implications:

    • This method enhances the safety and efficacy of intravascular foreign body retrieval.
    • It offers a solution for challenging cases involving fixed or centrally located emboli.
    • The technique may reduce the need for open surgical intervention.
