Virtual Reality-3D Modeling for Minimally Invasive Neuro-Interventional Planning

The treatment of intracranial aneurysms is a challenging aspect of neuro-interventional surgery, necessitating precise surgical planning to ensure optimal patient outcomes. In recent years, virtual reality (VR) technology has become a promising tool for enhancing surgical planning by providing surgeons access to immersive, patient-specific anatomical models in a virtual 3D environment1,2,3,4,5,6,7,8. This article presents a comprehensive protocol for the use of medical imaging and segmentation, 3D modeling, VR surgical planning, and idealized virtual roadmap generation to aid in surgical planning for the treatment of aneurysms.
The combination of these steps culminates in a virtual surgical planning approach, allowing physicians to immerse themselves in a virtual environment and gain a comprehensive understanding of a patient&#39;s unique anatomy prior to a surgical procedure. This immersive approach empowers surgeons to explore optimal positioning and simulate various procedural scenarios. Recording these scenarios can provide insight into the placement of real-world surgical equipment, such as C-arm positioning.
In addition to positioning angles, it is also possible to measure anatomy in a virtual environment using measurement tools designed for 3D space. These measurements can provide insight into the correct sizing and shape of the device to be used in an intracranial aneurysm case9.
This protocol presents a comprehensive process&#160;that seamlessly combines medical imaging, image segmentation, VR model preparation, and virtual surgical roadmap generation to enhance the surgical planning process. Using a combination of leading-edge technologies, this protocol provides opportunities to save valuable time in the operating room10, as well as a boost to surgeon confidence and understanding of complex surgical cases11,12,13.

Endovascular treatment of complex vascular anomalies shifts the risk of open surgical procedures to the benefit of minimally invasive endovascular procedural solutions. Complex open surgical procedures used to be the only option for the treatment of a myriad of conditions like pulmonary and aortic valve replacement as well as cerebral aneurysm repair. However, due to advancements in catheter-delivered devices and operator expertise, these procedures (along with many others) can now be performed through minimally invasive procedures delivered through a central or peripheral vein or artery. The decision to shift from an open procedure to an endovascular approach is based on multi-modal imaging, often including 3D Digital Imaging and Communications in Medicine (DICOM) imaging datasets. Utilizing these 3D images, our lab generates 3D models of the pathologic anatomy, thereby allowing the pre-procedural analysis necessary to pre-plan critical components of the catheterization lab procedure, namely, C-arm positioning, 3D measurement, and idealized road-map generation. This article describes how to take segmented 3D models of patient-specific pathology and predict generalized C-arm positions, how to measure critical two-dimensional (2D) measurements of 3D structures relevant to the 2D fluoroscopy projections, and how to generate 2D fluoroscopy roadmap analogs that can assist in proper C-arm positioning during catheterization lab procedures.

Advancements in endovascular treatment have replaced complex open surgical procedures with minimally invasive options, like valve replacement and aneurysm repair. This paper proposes using three-dimensional (3D) modeling and virtual reality to aid in C-arm positioning, angle measurements, and roadmap generation for neuro-interventional catheterization lab procedural planning, minimizing procedure time.
