Minimally Invasive Mini-orbitozygomatic Approach for Clipping an Anterior Communicating Artery Aneurysm: Virtual Reality Surgical Planning

Virtual reality (VR) has increasingly been implemented in neurosurgical practice. A
patient with an unruptured anterior communicating artery (AcoA) aneurysm was
referred to our institution. Imaging data from computed tomography angiography
(CTA) was used to create a patient specific 3D model of vascular and skull base
anatomy, and then processed to a VR compatible environment. Minimally invasive
approaches (mini-pterional, supraorbital and mini-orbitozygomatic) were simulated
and assessed for adequate vascular exposure in VR. Using an eyebrow approach, aminiorbitozygomatic
approach was performed, with clip exclusion of the aneurysm from
the circulation. The step-by-step process of VR planning is outlined, and the advantages
and disadvantages for the neurosurgeon of this technology are reviewed.
