Summary
A new directional needle allows for easier antegrade guide wire placement during superficial femoral artery catheterization. This innovative device simplifies procedures, proving effective in over 25 patients without complications.
Area of Science:
- Vascular Access Techniques
- Interventional Radiology
- Medical Device Innovation
Background:
- Traditional antegrade access for superficial femoral artery catheterization can be challenging.
- Limitations exist in current methods for guide wire placement.
Purpose of the Study:
- To introduce and evaluate a novel directional needle for antegrade guide wire placement.
- To assess the efficacy and safety of this new needle in superficial femoral artery procedures.
Main Methods:
- Development of a directional needle with a closed pencil-point tip and distal side hole.
- Application of the needle in over 25 patients undergoing superficial femoral artery catheterization.
Main Results:
- The directional needle facilitated antegrade guide wire placement at a 90-degree puncture angle.
- No technical difficulties or complications were reported in any of the procedures.
- The device proved highly effective for diagnostic studies, angioplasty, and chemotherapy infusion.
Conclusions:
- The directional needle offers a safe and effective solution for achieving antegrade access to the superficial femoral artery.
- It overcomes difficulties associated with traditional antegrade approaches, enhancing procedural ease.
