Lateral-access spine surgery has many benefits, but adoption has been limited by a steep learning curve. Virtual reality (VR) is gaining popularity and lends itself as a useful tool in enhancing neurosurgical resident education. We thus sought to assess whether VR-based simulation could enhance the training of neurosurgery residents in lateral spine surgery. ⋯ VR-based simulation enhanced neurosurgical residents' ability to understand lateral access surgery. Immersive surgical simulation resulted in improved resident confidence with surgical technique and workflow, perceived improvement in anatomical knowledge, and simulation performance scores. Trainee perceptions on virtual simulation and training as a curriculum supplement also improved following completion of VR training.

Observational Study
Aneurysm treatment with the Pipeline Vantage Embolization Device in Retrospective Evaluation: Periprocedural results from the Pipe-VADER study.
The Pipeline Vantage Embolization Device is a fourth-generation flow diverter with an antithrombotic coating and a reduced profile compared to previous Pipeline versions. The objective of this study was to evaluate the procedural feasibility, safety, and efficacy of this device. ⋯ The new Pipeline Vantage appears to be safe and feasible for the treatment of intracranial aneurysms and warrants further evaluation.

Three-dimensional (3D) printed models are used in the medical field. This study aimed to evaluate the feasibility and safety of a 3D-printed guide plate for use in brain biopsy. ⋯ The 3D-printed guide plate was noninvasive and had acceptable accuracy and the flexibility of frameless systems. The economic and operative benefits of this device supported its status as a powerful tool for brain biopsy in medical facilities in economically disadvantaged areas or institutions without navigation systems.

The collar sign has been previously described as an angiographic indicator of incomplete occlusion after deployment of a pipeline embolization device (PED) for intracranial aneurysms. In the present study, we explore the predictors for a collar sign in aneurysms treated with the PED. ⋯ The presence of a branch vessel arising from the aneurysm neck or dome, an increased dome/neck ratio, aneurysm diameter, and previous treatment are the strongest predictive factors for a collar sign in the angiographic follow-up of PED-treated aneurysms.

Brucellar cervical epidural abscess (CEA) is a rare condition with potentially permanent neurological damage if left untreated. This study aims to define the clinical presentation of brucellar CEA and evaluate the outcome of surgical treatment, specifically decompression and fusion surgery. The findings will contribute to understanding whether all patients with brucellar CEA could benefit from this surgical intervention. ⋯ Brucellosis should be considered as a potential cause of CEA, especially in endemic areas. Timely detection and effective management of this condition are crucial in order to minimize the associated morbidity and mortality. For patients with detectable brucellar CEA, we recommend decompression and fusion surgery.
