Summary

This study will evaluate the application of a metaverse-based surgical simulation platform in extracranial-intracranial (EC-IC) bypass surgery. The study population will include patients with moyamoya disease or chronic cerebral ischemia who are scheduled to undergo EC-IC bypass surgery.

Before surgery, preoperative brain computed tomography images will be imported into the metaverse surgical simulation platform. During surgery, extended reality technology will be used to provide precise localization of the relevant vessels, including both the donor and recipient arteries.

The primary objective is to assess the localization accuracy of this platform. The study will also investigate whether this technology can facilitate a minimally invasive surgical approach and improve surgical safety.

Interventions

DEVICE

NTU OpVerse surgical simulation platform

NTU OpVerse is a patient-specific metaverse-based surgical simulation and assistance platform developed through collaboration among National Taiwan University Hospital, National Taiwan University, and technology partners. The platform integrates medical-image processing, three-dimensional reconstruction, digital-twin technology, and extended reality, including virtual, augmented, and mixed-reality applications. Patient-specific computed tomography or magnetic resonance imaging data can be imported into the platform and reconstructed into interactive three-dimensional anatomical models. These models allow surgeons to visualize the spatial relationships among target lesions, blood vessels, organs, bones, and other relevant anatomical structures. Through an immersive extended-reality interface, surgeons can manipulate the reconstructed models, examine them from different perspectives, and conduct individualized preoperative planning and procedural simulation.
