ConclusionThis combined approach allows safe clipping of such PICA aneurysms.

The objective of this study was to evaluate the gut microbiome in a preclinical TBI cortical impact model. Male rats underwent craniotomy and randomized to a sham group (nā€Š=ā€Š4), or a moderate TBI (nā€Š=ā€Š10) using a pneumatic impactor. MRI and behavioral assessments were performed pre-TBI and on days 2, 7, and 14 days thereafter. Microbiome composition was determined with 16s rRNA sequencing from fecal sample DNA pre-TBI and 2 hrs, 1, 3, and 7 days afterward. Alpha- and β-bacterial diversity, as well as organizational taxonomic units (OTUs), were determined. Significant changes in the gut microbiome were evident ...

Conclusions: Morphometry of the bony canal of MMA shall be important for safely expose and preserve the artery during craniotomy with careful drilling and shall be useful for those who have interest in this anatomical site.

CONCLUSIONS: This transmuscular technique for identification of the OA is a reliable method and may facilitate exposure and protection of the OA during a retrosigmoid approach. This technique may obviate the need for larger incisions when planning a bypass to nearby arteries in the posterior circulation via a retrosigmoid craniotomy. Additionally, the small skin incision can be enlarged when a different craniotomy and/or bypass is planned or when a greater length of the OA is needed to be harvested.

ConclusionsProlonged operative time can increase the SSI risk for neurosurgery patients. Intensive interventions should be taken to decrease operative duration.

ConclusionSpheno-orbital meningiomas are highly complex tumours. Surgical approaches should be tailored to the patient but good clinical and cosmetic outcomes may be achieved with a smaller craniotomy and custom-made implants, irrespective of whether the operation is the patient ’s first procedure.

This study aimed to evaluate the impact of a skull defect and the interpretation criteria of images on this diagnostic test. MATERIALS AND METHODS: A series of consecutive patients with a clinical diagnosis of brain death underwent CTA (case group), while the control group comprised patients with acute ischemic stroke in the same period. CTA criteria adopted to confirm brain death were the absence of opacification of the M4 branches and internal cerebral veins. The evaluation also included the presence of "stasis filling." Cases were stratified as intact skull, craniotomy, and craniectomy. Three neuroradiologist...

ConclusionsEarly seizures, including non-convulsive, occurred in 7% of our patients. Within this group, non-convulsive seizure activity had longer durations than clinically overt seizures, but only 1% of patients had exclusively non-convulsive seizures. Seizures were not associated with unexpected neurological deterioration.

We performed a retrospective case-control study to investigate the utility of the Gupta, RCRI, KPS, ASA, and NSQIP risk calculators in predicting complication and mortality rates among a neurosurgical patient population undergoing elective craniotomy and used ROC curves to determine their relative predictive accuracy. We identified 17 patients who died following elective craniotomy ...
