Percutaneous puncture guided by ultrasonic multitransducer scanning.

Area of Science:

• Medical imaging
• Interventional radiology
• Ultrasound technology

Background:

• Percutaneous procedures require precise needle guidance.
• Real-time imaging enhances accuracy and safety in interventions.
• Existing methods may have limitations in needle trajectory control.

Purpose of the Study:

• To describe a novel technique for ultrasound-guided percutaneous puncture.
• To demonstrate the ability to guide a needle at an adjustable angle within the scanning plane.
• To evaluate the applicability of this technique in various clinical scenarios.

Main Methods:

• Development of a special puncture adaptor for a multitransducer ultrasound device.
• Guiding a needle through the adaptor, maintaining it within the scanning plane.
• Utilizing real-time ultrasound to visualize both the needle and the target throughout the procedure.

Main Results:

• The technique allows continuous monitoring of the needle and puncture target.
• The needle can be guided at an adjustable angle relative to the transducer.
• Successful application demonstrated in amniocentesis, renal mass biopsy, renal cyst puncture, and pericardiocentesis.

Conclusions:

• This real-time ultrasound-guided puncture technique offers enhanced control and visualization.
• The method is versatile and applicable to a range of common percutaneous interventions.
• It has the potential to improve safety and efficacy in guided needle procedures.
