Brain mapping techniques (intraoperative neurophysiology and intraoperative neuropsychology) represent the gold standard in glioma surgery; these techniques have been proven to be the gold standard in glioma resection. From the introduction of MRI in clinical routine, several advanced applications have been developed like functional MRI and tractography based on diffusion imaging. Both techniques have application in glioma surgery. The fMRI allows to identify cortical areas related to a specific function, DTI allow to reconstruct a model of the sub-cortical connectivity...

INTRODUCTION: Cervical spondylotic myelopathy (CSM) most commonly occurs at the C3-7 levels and is successfully treated by multilevel anterior cervical discectomy and fusion (ACDF) or cervical laminectomy and fusion (CLF), but no procedure has clearly demonstrated superiority. Most prior investigations comparing approaches are limited by marked heterogeneity in the composition of the study groups. This investigation compares ACDF versus CLF surgery specifically at C3-7 in terms of long-term neurological outcome and the fate of the adjacent levels...

BACKGROUND: Despite advancements in the treatment of high-grade gliomas (HGG), the rate of tumor recurrence is high and survival rate for the patient is low. Gross total resection has shown increased survival but the location of the tumor in the eloquent brain poses significant risk of morbidity. In this report, we focus on modern surgical nuances for resection of tumors located in the eloquent brain. METHODOLOGY: Research of the literature was conducted using the following search terms: surgical resection of gliomas, high-grade gliomas, and the role of vascular encasement-from 1986-2018...

BACKGROUND: Non-invasive language mapping is commonly facilitated via two different approaches, functional magnet resonance imaging (fMRI) and navigated transcranial magnetic stimulation (nTMS). The aim of our examination was to compare both methods regarding hemispheric dominance and detection of involved cortex in speech-processing. METHODS: Since 2015, patients with language eloquent tumors received both fMRI and nTMS language mapping in our facility. Hemispheric dominance for fMRI (word pairing task) and nTMS (picture naming) was defined according to activation/response predominance between hemispheres...

INTRODUCTION: The awake craniotomy has evolved from its humble beginnings in ancient cultures to one of the most eloquent modern neurosurgical procedures for the resection of gliomas. The development of intraoperative mapping techniques like direct electrostimulation of the cortex and subcortical white matter have further argued for its place in the neurosurgeon's armamentarium. Yet the suitability of the awake craniotomy with intraoperative functional mapping (ACWM) to optimize oncofunctional balance continues to be a topic of active investigation as new methods of intraoperative monitoring and some unfavorable outcome data question its necessity...

BACKGROUND: Spinal arteriovenous malformations (AVMs) are rare disease entities with significant morbidity if untreated. Risk factors of complications, hospitalization and costs-of-care remain in need of characterization. METHODS: Using the National Inpatient Sample years 2002-2014, adult subjects with spinal AVMs who underwent either laminectomy with lesion excision or endovascular embolization were extracted using ICD-9-CM diagnostic code 747.82. Predictors of inpatient complications, hospital length of stay (HLOS), and discharge home were evaluated using multivariable regression...

BACKGROUND: Acute subdural hematoma represents an important cause of disability and mortality. Its surgical treatment takes advantage of two surgical procedures: craniotomy and decompressive craniectomy, nevertheless the effectiveness of one procedure rather than the other is still debated. This study was conducted to identify which of the surgical procedures could provide better neurological outcome after traumatic acute subdural hematoma; as a secondary endpoint, the study tries to settle pre-operative prognostic factors useful to identify the most appropriate surgical technique for every specific patient and kind of trauma...

Over the last few decades, cerebrovascular surgery has gravitated towards a minimally invasive philosophy without compromising the foundational principles of patient safety and surgical efficacy. Enhanced radiosurveillance modalities and increased average life expectancy have resulted in an increased reported incidence of intracranial aneurysms. Although endovascular therapies have gained popularity in the recent years, microsurgical clipping continues to be of value in the management of these aneurysms owing to its superior occlusion rates, applicability to complex aneurysms and reduced retreatment rates...
