Thousands of neurosurgical emergencies are transferred yearly to tertiary care facilities to assume a higher level of care. Several studies have examined how neurosurgical transfers influence patient outcomes, but characteristics of potentially avoidable transfers have yet to be investigated. ⋯ CI, confidence intervalIQR, interquartile rangeJT, justifiable transferOR, odds ratioPAT, potentially avoidable transferUAB, University of Alabama at Birmingham.

Thin-walled regions (TWRs) of cerebral aneurysms are at high risk of rupture, and careful attention should be paid during surgical procedures. Despite this, an optimal imaging technique to estimate TWRs has not been established. Previously, pressure elevation at TWRs was reported with computational fluid dynamics (CFD) but not fully evaluated. ⋯ CFD, computational fluid dynamicsMCA, middle cerebral arteryPave, average pressurePD, pressure differencePmax, maximum pressureTWR, thin-walled regionWSS, wall shear stress.

Occipitocervical junction instability can lead to serious neurological injury or death. Open surgical fixation is often necessary to provide definitive stabilization. However, long-term results are limited to small case series. ⋯ AIS, American Spinal Injury Association Impairment ScaleCVJ, craniovertebral junctionmJOAS, modified Japanese Orthopaedic Association ScaleNLI, neurological level of injurySCI, spinal cord injury.

Association Patterns of Simultaneous Intraventricular and Intraparenchymal Intracranial Pressure Measurements.
The process of measuring intracranial pressure (ICP) can be accomplished using a variety of monitors placed primarily either in the ventricles or brain parenchyma. ⋯ CSF, cerebrospinal fluidEVD, external ventricular drainICP, intracranial pressureIPM, intraparenchymal monitorTBI, traumatic brain injury.

Individualized Map of White Matter Pathways: Connectivity-Based Paradigm for Neurosurgical Planning.
Advances in white matter tractography enhance neurosurgical planning and glioma resection, but white matter tractography is limited by biological variables such as edema, mass effect, and tract infiltration or selection biases related to regions of interest or fractional anisotropy values. ⋯ AF, arcuate fasciculusDTI, diffusion tensor imagingIFOF, inferior fronto-occipital fasciculusILF, inferior longitudinal fasciculusROI, region of interestWM, white matter.
