The use of intraoperative MR and direct DBS targeting, relies on anatomical rather than functional data. Historical clinical outcome databases that have recorded stimulation location and magnitude of effect, can provide a useful adjunct in DBS targeting strategies. We present a method for generating clinical outcome topographies, and merging regions of effect onto a pre-operative MR, for surgical planning. The clinical outcome topographies are consistent with more intuitive strategies used by neurosurgeons...

Due to the aging population, neurosurgeons are confronted with an increasing number of very old patients suffering from traumatic brain injury. Many of these patients present with an acute subdural hematoma. There is a lack of data on neurosurgical decision-making in elderly people. We investigated the importance of imaging criteria, patients' wishes, their surrogates' wishes, and patient demographics on treatment decisions chosen by neurosurgeons. An online questionnaire was sent to all German neurosurgical units via the German Society of Neurosurgery (DGNC)...

The lack of a simple, objective and reproducible system to describe glioblastoma multiforme (GBM) represents a major limitation in comparative effectiveness research. The objectives of this study were therefore to develop such a grading system and to validate it on patients who underwent surgical resection. A systematic review of the literature was performed to identify features on pre-operative magnetic resonance imaging (MRI) that predict the surgical outcome of patients with GBM. In all, the five most important features of GBM on pre-operative MRI were as follows: periventricular or deep location, corpus callosum or bilateral location, eloquent location, size and associated oedema...

BACKGROUND: The P1 segment of the posterior cerebral artery (PCA) begins at the termination of the basilar artery and ends at the origin of posterior communicating artery (PCoM), within the interpeduncular cistern. Perforating branches arising from this segment are called posterior thalamoperforating arteries and the main and biggest artery among those is called thalamoperforating artery (TPA). Perforating branches are a crucial component of cerebrovascular system supplying the posterior part of the thalamus, subthalamus, hypothalamus, substantia nigra, perforated substance, posterior part of internal capsule and the nucleus of III and IV cranial nerve...

PURPOSE: To investigate the ability of slip interface imaging (SII), a recently developed magnetic resonance elastography (MRE)-based technique, to predict the degree of meningioma-brain adhesion, using findings at surgery as the reference standard. MATERIALS AND METHODS: With Institutional Review Board approval and written informed consent, 25 patients with meningiomas >2.5 cm in maximal diameter underwent preoperative SII assessment. Intracranial shear motions were introduced using a soft, pillow-like head driver and the resulting displacement field was acquired with an MRE pulse sequence on 3T MR scanners...

Spontaneous intracranial hypotension (SIH) is a condition of low cerebrospinal fluid (CSF) volume and pressure caused by a leak of CSF through a dural defect. Diagnosis and management can be difficult, often requiring coordination between multiple disciplines for myelography, blood patching, and possible surgical repair. Patients should be monitored closely, as they can deteriorate into a coma or even death. There are no widely accepted guidelines for the management of SIH. Herein, we review the existing SIH literature, illustrate management challenges via a case review, and propose an algorithm developed by neurosurgeons, radiologists, and anesthesiologists intended to simplify and streamline the management of SIH...

BACKGROUND: Evidence of a high interobserver variability of the subjective House-Brackmann facial nerve grading system (HBGS) would justify cost- and time-consuming technological enhancements of objective classifications for facial nerve paresis. METHOD: A total of 112 patients were recruited for a randomized multi-center trial to investigate the efficacy of prophylactic nimodipine treatment in vestibular schwannoma (VS) surgery. For the present investigation both treatment groups were pooled for the assessment of facial nerve function preoperatively, in the early postoperative course and 1 year after the surgery...

The care of patients with shunted hydrocephalus can be complicated. The best assessment is provided when all data are available to the neurosurgery practitioner. However, data can be time-consuming to gather, especially in the setting of a busy practice, a trainee environment with duty-hour restrictions, and an electronic medical record (EMR) not specifically designed for the needs of subspecialists. For these reasons, the complete clinical picture, especially the historical component, is sometimes not assembled...

Tumoral calcinosis is characterized by tumor-like deposition of calcium in periarticular soft tissue. Spinal involvement is rare, and perioperative diagnosis of tumoral calcinosis can be difficult because lesions may be confused with bony neoplasms. Symptoms of tumoral calcinosis result from bony involvement and/or direct compression of surrounding anatomical structures, for which treatment with surgical decompression can be highly successful. The craniovertebral junction is rarely affected by tumoral calcinosis, and patients with this condition may present with distinct symptoms...

Intraoperative hemostasis during neurosurgical procedures is one of the most important aspects of intracranial surgery. Hemostasis is mandatory to keep a clean operative field and to prevent blood loss and postoperative hemorrhage. In neurosurgical practice, biosurgical hemostatic agents have proved to be extremely useful to complete the more classic use of electrocoagulation. During recent years, many biosurgical topical hemostatic agents were created. Although routinely used during neurosurgical procedures, there is still a great deal of confusion concerning optimal use of these products, because of the wide range of products, as absorbable topical agents, antifibrinolytics agents, fibrin sealants and hemostatic matrix, which perform their hemostatic action in different ways...

Subarachnoid hemorrhage (SAH) has a global incidence of 9/100,000. In low-resource settings, where neurosurgical capacity is diminished through fewer human and technological resources, neurosurgeons may not be prepared to operate on aneurysmal SAH. Through a case illustration of an Iranian neurosurgeon faced with a decision to operate on a patient presenting with aneurysmal SAH in a low-resource setting, we highlight the importance of mastery of neurosurgical anatomy, which was critical in achieving a favorable patient outcome...

INTRODUCTION: Awake craniotomy for brain tumor resection is usually well-tolerated and most of the patients are satisfied. However, in studies reporting the patients' postoperative perception of the awake craniotomy procedure, about half of them have experienced some degree of intraoperative pain. Pain was mild (intensity between 1 and 2 on the visual analogical score) short lasting in most cases, and did not challenge the procedure. Pain was reported as moderate in about 25% and exceptionally severe...

Intramedullary tumors constitute approximately 5% of spinal tumors and about 80% are of neuroglial origin. We reviewed our series of adult patients with spinal neuroglial intramedullary tumors operated on between 1984 and 2011 at the neurosurgical department of Bicêtre hospital. The histopathological records for 196 patients were retrospectively analyzed. The majority of tumors were ependymomas (68%) and astrocytomas (27.5%). The importance of a proper and detailed neuropathological diagnosis is the key to define patient management...
