Minimizing Risks in Anterior Endoscopic Cervical Discectomy Using Ultrasound-Guided Hydrodissection: A Technical...

Area of Science:

• Minimally Invasive Spine Surgery
• Cervical Spine Procedures
• Surgical Navigation Technologies

Background:

• Anterior endoscopic cervical discectomy (AECD) is a minimally invasive surgical option for cervical disc herniation.
• Standard AECD carries risks of iatrogenic injury to adjacent vital structures like the esophagus and major arteries.
• Enhanced visualization and protection are needed to improve AECD safety.

Purpose of the Study:

• To introduce and evaluate a novel ultrasound-guided hydrodissection technique for anterior endoscopic cervical discectomy (AECD).
• To enhance intraoperative visualization of critical anatomical structures during AECD.
• To reduce the risk of iatrogenic injury associated with AECD.

Main Methods:

• Development of a technique combining real-time ultrasound imaging with hydrodissection.
• Ultrasound is used to identify critical structures (esophagus, nerves, vessels) before and during needle advancement.
• Hydrodissection is employed to create a safe, fluid-filled space, protecting tissues during instrument insertion.

Main Results:

• The ultrasound-guided hydrodissection technique allows for precise real-time identification of anatomical landmarks.
• Hydrodissection effectively creates a buffer zone, minimizing direct contact and trauma to surrounding delicate structures.
• The technique facilitates safer and more accurate needle placement for AECD.

Conclusions:

• Ultrasound-guided hydrodissection is a promising adjunct for enhancing the safety of anterior endoscopic cervical discectomy (AECD).
• This integrated approach has the potential to significantly reduce complications and improve procedural accuracy in AECD.
• The technique offers a valuable method for minimizing iatrogenic injury during minimally invasive cervical spine surgery.
