Summary
Augmented reality (AR) enhances neurosurgery by improving vessel identification and craniotomy planning for extracranial-to-intracranial bypass procedures. This technology optimizes surgical workflow and enables minimally invasive techniques.
Area of Science:
- Neurosurgery
- Medical Imaging
- Augmented Reality
Background:
- Augmented reality (AR) is utilized for image guidance in neurosurgery.
- Its application in extracranial-to-intracranial bypass procedures remains unexplored.
- AR offers potential solutions for challenges in bypass surgery, such as precise vessel localization.
Purpose of the Study:
- To evaluate the utility of an AR-based system for neurosurgical bypass procedures.
- To assess AR's effectiveness in real-time donor vessel harvesting and recipient vessel identification.
- To determine if AR aids in performing tailored craniotomies for anastomosis.
Main Methods:
- The AR system was applied to four patients undergoing bypass surgery (3 Moya-Moya, 1 vertebral artery dissection).
- Preoperative 3D imaging data (DSA, angio-MRI, angio-CT) were segmented.
- Virtual images were integrated into the operating microscope eyepiece for intraoperative guidance.
Main Results:
- The AR setup facilitated precise localization of both donor and recipient vessels.
- Tailoring of craniotomies was accurately achieved based on the integrated virtual images.
- The system provided real-time anatomical information directly within the surgical field.
Conclusions:
- The AR-based system optimizes extracranial-to-intracranial bypass procedures.
- It enhances surgical workflow by providing integrated anatomical information.
- The technology supports the performance of minimally invasive neurosurgical interventions.
