The cuatico aspiration cannula as a depth guide during myelography

Area of Science:

• Medical Devices
• Anesthesiology
• Neurosurgery

Background:

• Accurate needle placement is crucial in procedures involving the subarachnoid space.
• Extra-arachnoid injection of contrast material can lead to complications and diagnostic inaccuracies.
• The Cuatico needle is used in specific neurosurgical and anesthesiological interventions.

Purpose of the Study:

• To describe a novel technique for precise Cuatico needle positioning.
• To detail a method that prevents extra-arachnoid injection of contrast material.
• To introduce a technique that facilitates contrast medium removal.

Main Methods:

• The described technique utilizes the aspiration cannula of the Cuatico needle system.
• The aspiration cannula functions as a reliable depth guide for accurate needle placement.
• This method ensures the needle tip remains within the desired compartment, avoiding the extra-arachnoid space.

Main Results:

• The technique effectively prevents the unintended injection of contrast material into extra-arachnoid spaces.
• Accurate depth guidance is achieved through the use of the aspiration cannula.
• The procedure allows for easier and more complete removal of contrast medium post-injection.

Conclusions:

• This technique offers a safe and effective approach to Cuatico needle placement.
• Utilizing the aspiration cannula as a depth guide enhances procedural accuracy and patient safety.
• The method simplifies contrast medium management during these interventions.
