To identify the significant prognostic factors of overall survival (OS) for patients living with meningiomas (MMs), and establish a novel graphical nomogram and an online dynamic nomogram. ⋯ Age of diagnosis, sex, tumor size, tumor histology, and radiotherapy were independent predictors for OS, while extent of resection had a borderline significant. A nomogram model was successfully developed and validated to dynamically predict the long-term OS for MM patients, expecting to help neurosurgeons optimize clinical management and treatment strategies.

Tandem occlusion accounts for 10%-20% of all large vessel occlusion strokes and often yields a poor recanalization rate. The endovascular treatment of tandem lesions is still controversial. This study uses an endovascular treatment strategy, "guided catheter recovery balloon (GRB)" for the treatment of acute anterior circulation tandem occlusion. ⋯ GRB technique showed a high recanalization rate when applied to the treatment of acute anterior circulation tandem occlusion.

To evaluate the safety profile of bis-chloroethyl-nitrosourea (BCNU) wafer implantation after malignant glioma resection with or without ventricular opening (VO). ⋯ This study showed that VO during surgery with BCNU wafer implantation might not influence the occurrence of postoperative AEs. If VO happens, BCNU wafer implantation can be performed safely with accurate closing of the ventricle.

The association of various morphological features of facet diastasis with posterior ligamentous complex (PLC) injury has not been previously described. This study aims to determine the diagnostic value of facet diastasis subtypes for diagnosing thoracolumbar PLC injury. ⋯ Facet dislocation, subluxation, and displaced facet fracture, but not undisplaced facet fracture or FJW, were independently associated with PLC injury. Therefore, we propose to define facet diastasis as a surrogate marker of PLC injury in MRI based on these morphologies.

To understand the factors that affect decision-making when choosing a specific subspecialty while exploring gender and geographic variables. ⋯ Stereotactic and functional neurosurgery and peripheral nerve surgery are the emerging subspecialties and hence their exposure and access are highly limited to the developed world whereas spine and neurosurgical oncology branches had a homogenous geographic presence. Pediatric neurosurgery had the most female representation, thereby necessitating the need to uplift women in other subspecialties.
