Аннотация: ABSTRACTBackground: External ventricular drainage (EVD) is a critical neurosurgical procedure for managing conditions.Despite its widespread use, EVD placement is associated with specific risks, as improper catheter positioningcan lead to severe complications. Recent advancements in augmented reality (AR) technology present newopportunities to improve the precision and safety of surgical interventions.Methods: This study presents a new AR-assisted approach for EVD placement, utilizing the MicrosoftHoloLens 2 and the Medgital software. We conducted a clinical trial involving three patients requiring EVDdue to acute hydrocephalus or subarachnoid hemorrhage. The study adhered to ethical standards and wasapproved by an Ethics Committee, with informed consent obtained from all participants. Two alignmentmethods were employed: cranial landmark-based and QR code-based alignment. Preoperative imagingfacilitated the creation of patient-specific 3D models, which were aligned with the patient’s anatomy duringsurgery.Results: The results suggest that AR navigation may improve the accuracy of catheter placement. In the firstcase, EVD was placed with a deviation of 2.3 mm from the planned trajectory, while the second and third casesachieved deviations of 1.5 mm and 0.5 mm, respectively. These results indicate the potential effectiveness of theAR system. Importantly, no postoperative complications were observed, suggesting the safety of the AR-guidedapproach.Conclusion: This study suggests the viability of AR-assisted navigation in neurosurgical practice,particularly for EVD placement. The promising results support further exploration and integration ofAR technologies in surgical settings, aiming to improve patient outcomes and procedural efficiency inneurosurgery.Keywords: Augmented reality navigation, Augmented reality, External ventricular drain, Microsoft HoloLens 2,Neurosurgery
