BACKGROUND: Use of diffusion tensor imaging (DTI) in brain tumor resection has been limited in part by a perceived difficulty in implementing the techniques into neurosurgical practice. OBJECTIVE: To demonstrate a simple DTI postprocessing method performed without a neuroscientist and to share results in preserving patient function while aggressively resecting tumors. METHODS: DTI data are obtained in all patients with tumors located within presumed eloquent cortices...

The awake brain surgery is an innovative approach in the treatment of tumors in the functional areas of the brain. There are various anesthetic techniques for awake craniotomy (AC), including asleep-awake-asleep technique, monitored anesthesia care, and the recent introduced awake-awake-awake method. We describe our first experience with anesthetic management for awake craniotomy, which was a combination of these techniques with scalp nerve block, and propofol/rémifentanil target controlled infusion. A 28-year-oldmale underwent an awake craniotomy for brain glioma resection...

BACKGROUND: During awake craniotomy for tumor resection, a neuropsychologist (NP) is regarded as a highly valuable partner for neurosurgeons. However, some centers do not routinely involve an NP, and data to support the high influence of the NP on the perioperative course of patients are mostly lacking. OBJECTIVE: The aim of this study was to investigate whether there is a difference in clinical outcomes between patients who underwent awake craniotomy with and without the attendance of an NP...

OBJECTIVE Resection of intraaxial tumors adjacent to the optic radiation (OR) may be associated with postoperative visual field (VF) deficits. Intraoperative navigation using MRI-based tractography and electrophysiological monitoring of the visual pathways may allow maximal resection while preserving visual function. In this study, the authors evaluated the value of visual pathway mapping in a series of patients undergoing awake craniotomy for tumor resection. METHODS A retrospective analysis of prospectively collected data was conducted in 18 patients who underwent an awake craniotomy for resection of intraaxial tumors involving or adjacent to the OR...

Intra-axial brain tumors located at anatomically eloquent areas are challenging conditions. It is often difficult to pursue maximum extent of resection of the tumor in these locations. On the other hand, neuroplasticity takes place in some patients with low-grade glioma and the primary neural functions are known to sometimes shift from conventional "eloquent cortices". In the presented case, the authors detected shift of primary motor function from the precentral gyrus to the postcentral gyrus on magnetoencephalography and functional magnetic resonance imaging in a patient suffering from a lower-grade glioma located at the precentral gyrus...

Patients with obstructive sleep apnea are frequently considered unsuitable candidates for awake craniotomy due to anticipated problems with oxygenation, ventilation, and a potentially difficult airway. At present, only a handful of such accounts exist in the literature. Our report describes the novel use of high-flow nasal oxygen therapy for a patient with moderate obstructive sleep apnea who underwent an awake craniotomy under deep sedation. The intraoperative application of high-flow nasal oxygen therapy achieved satisfactory oxygenation, maintained the partial carbon dioxide pressure within a reasonable range even during periods of deep sedation, permitted responsive patient monitoring during mapping, and provided excellent patient and surgeon satisfaction...

OBJECTIVE There is ample evidence that extent of resection (EOR) is associated with improved outcomes for glioma surgery. However, it is often difficult to accurately estimate EOR intraoperatively, and surgeon accuracy has yet to be reviewed. In this study, the authors quantitatively assessed the accuracy of intraoperative perception of EOR during awake craniotomy for tumor resection. METHODS A single-surgeon experience of performing awake craniotomies for tumor resection over a 17-year period was examined...

Left spatial neglect is a debilitating condition that may occur after lesion of many cortical territories in the right hemisphere. At the subcortical level, the second and third branches of the right superior longitudinal fasciculus has emerged as strong candidates in conveying information exchanges within the attention networks as their damage has been repeatedly associated to spatial neglect in neuromodulation and neuropsychological studies. Yet, a few cases of spatial neglect have also been observed after damage to the right inferior fronto-occipital fasciculus (IFOF), suggesting an involvement of this associative connectivity in spatial attention...

We propose electrocorticographic temporal alteration mapping (ETAM) for motor cortex mapping by utilizing movement-related cortical potentials (MRCPs) within the low-frequency band [0.05-3] Hz. This MRCP waveform-based temporal domain approach was compared with the state-of-the-art electrocorticographic frequency alteration mapping (EFAM), which is based on frequency spectrum dynamics. Five patients (two epilepsy cases and three tumor cases) were enrolled in the study. Each patient underwent intraoperative direct electrocortical stimulation (DECS) procedure for motor cortex localization...

BACKGROUND: Conscious sedation during awake craniotomy requires balanced anaesthesia technique to achieve optimum sedation and analgesia. This technique should be done without causing respiratory depression or loss of consciousness. The present study aims at evaluating the effect of propofol-dexmedetomidine versus propofol-remifentanil conscious sedation during awake craniotomy for epilepsy surgery. METHODS: Sixty patients undergoing awake craniotomy for epilepsy surgery were randomly divided into two groups, PD group and PR group...

OBJECTIVE Postoperative seizures are a common complication in patients undergoing an awake craniotomy, given the cortical manipulation during tumor resection and the electrical cortical stimulation for brain mapping. However, little evidence exists about the efficacy of postoperative seizure prophylaxis. This study aims to determine the most appropriate antiseizure drug (ASD) management regimen following an awake craniotomy. METHODS The authors performed a retrospective analysis of data pertaining to patients who underwent an awake craniotomy for brain tumor from 2007 to 2015 performed by a single surgeon...

BACKGROUND: Awake craniotomy for tumor resection and epilepsy surgery is a well-tolerated procedure. Qualitative data on patients' experience of awake deep-brain stimulation (DBS) are, however, lacking. We collected qualitative data on patients' experience of awake DBS with a view to identifying areas for improvement. METHODS: Forty-one patients undergoing DBS for Parkinson disease between 2009 and 2015 were surveyed with a structured questionnaire designed to receive patient feedback regarding perioperative management of the awake stage of the procedure...

INTRODUCTION: Intraoperative application of electrical current to the brain is a standard technique during brain surgery for inferring the function of the underlying brain. The purpose of intraoperative functional mapping is to reliably identify cortical areas and subcortical pathways involved in eloquent functions, especially motor, sensory, language and cognitive functions. MATERIAL AND METHODS: The aim of this article is to review the rationale and the electrophysiological principles of the use of direct bipolar electrostimulation for cortical and subcortical mapping under awake conditions...
