Using virtual lines of navigation for a successful transcortical approach

Area of Science:

• Neurosurgery
• Medical Technology
• Augmented Reality

Background:

• Neuronavigation systems are crucial for image-guided neurosurgery, aiding in precise tumor resection.
• Advancements include augmented reality (AR) projection for enhanced surgical visualization.
• The transcortical approach, while common, risks disorientation and brain damage with deep lesions.

Purpose of the Study:

• To report a case utilizing AR virtual lines to assist the transcortical approach.
• To evaluate the efficacy of AR guidance in navigating deep brain lesions.

Main Methods:

• A virtual navigation line was created using Stealth station S7® neuronavigation.
• This AR virtual line was projected onto the microscope eyepiece.
• The surgical team navigated through white matter following the AR line.

Main Results:

• The virtual line facilitated direct access to the target lesion.
• The approach was completed quickly and without disorientation.
• Successful navigation through white matter was achieved.

Conclusions:

• AR-guided virtual lines offer a simple and accurate method for transcortical approach.
• This technique effectively supports conventional neurosurgical procedures.
• Neuronavigation with AR enhances precision and reduces risks in brain surgery.
