Summary
Pumping the stylet within a needle during ultrasound (US) procedures enhances needle tip visualization. This "pump maneuver" improves localization for US-guided biopsies and drainage, offering a simple, atraumatic technique.
Area of Science:
- Medical imaging
- Interventional radiology
- Ultrasound technology
Background:
- Real-time ultrasound (US) guidance is crucial for percutaneous procedures like biopsies and drainage.
- Optimal visualization of the needle tip is essential for procedural success and patient safety.
Purpose of the Study:
- To introduce and evaluate a novel technique for enhancing needle tip visualization during US-guided procedures.
- To describe the
- pump maneuver
- as an adjunct for improving needle localization.
Main Methods:
- The study describes a technique involving the in-and-out movement of a stylet within a stationary needle shaft.
- This maneuver aims to increase the echogenicity of the needle, improving its visibility on ultrasound.
Main Results:
- The
- pump maneuver
- was found to increase the echogenicity of the needle shaft and tip.
- This enhancement facilitates easier and more reliable needle localization during procedures.
Conclusions:
- The
- pump maneuver
- is a quick, useful, and atraumatic technique.
- It serves as a valuable adjunct for improving needle visualization in US-guided percutaneous biopsies and drainage procedures.
