The middle meningeal artery (MMA) is a very important artery in neurosurgery. Many diseases, including dural arteriovenous fistula (DAVF), pseudoaneurysm, true aneurysm, traumatic arteriovenous fistula (AVF), moyamoya disease (MMD), recurrent chronic subdural hematoma (CSDH), migraine and meningioma, can involve the MMA. In these diseases, the lesions occur in either the MMA itself and treatment is necessary, or the MMA is used as the pathway to treat the lesions; therefore, the MMA is very important to the development and treatment of a variety of neurosurgical diseases...

This review summarizes the most up-to-date approach to the multidisciplinary management of patients with breast cancer brain metastases. A brief overview of the epidemiology and biology of breast cancer brain metastasis is provided. The perspectives of radiation oncology, neurosurgery, and medical oncology-and landmark studies from each discipline-are all discussed. We also offer practical tips to help guide the treating physician, including data on antiseizure medications. Finally, we introduce the concept of a multidisciplinary clinic that combines input from medical and radiation oncology, neurosurgery, and support services, which we developed at the University of North Carolina as a coordinated and optimal approach to the management of patients with this complex disease...

BACKGROUND: Patients presenting to the emergency department (ED) with altered mental status and alcohol intoxication can clinically resemble patients with an intracranial hemorrhage. Although intracranial hemorrhage is quickly excluded with a head computed tomographic (CT) scan, it is common practice to defer imaging and allow the patient to metabolize to spare ED resources and minimize radiation exposure to the patient. Although this reduces unnecessary scans, it may delay treatment in patients with occult intracranial hemorrhage, which some fear may increase morbidity and mortality...

BACKGROUND: Neuronavigation, the ability to perform real-time intra-operative guidance during cranial and/or spinal surgery, has increased both accuracy and safety in neurosurgery [2]. Cranial navigation of existing surgical instruments using Brainlab requires the use of an instrument adapter and clamp, which in our experience renders an endoscope 'top-heavy', difficult to manipulate, and the process of registration of the adapter quite time-consuming. METHODS: A Brainlab Disposable Stylet was used to navigate fenestration of an entrapped temporal horn in a pediatric case...

Hemangioblastomas (HBMs) are highly vascular tumors of the central nervous system. Sporadic HBMs are nearly always solitary, and solitary HBMs are similar to intracranial arteriovenous malformations due to their highly vascular characteristics. However, to the best of our knowledge, cases of HBM in the cerebellum mimicking an aneurysm have never been reported in the literature. The present study reports a case of an HBM on the right cerebellar hemisphere mimicking an aneurysm, which originated from the right posterior inferior cerebellar artery, as determined using magnetic resonance angiography and digital subtraction angiography...

Intraoperative rerupture (IOR) during clipping of cerebral aneurysms is a difficult complication of microneurosurgery. The aim of this study was to evaluate the incidence of IOR and analyze the strategies for controlling profound hemorrhage. A total of 165 patients with unruptured intracranial aneurysms and 46 patients with subarachnoid hemorrhage (SAH) treated surgically between April 2010 and March 2011, were reviewed. The data were collected with regard to age, sex, presence of symptoms, confounding factors and strategy for controlling intraoperative hemorrhage was analyzed in terms of location of aneurysms, timing of rupture and severity of IOR...

OBJECTIVES: The management of neonatal post-haemorrhagic hydrocephalus (nPHH) varies considerably between centres and even between neurosurgeons in the same centre. We performed a nationwide survey to evaluate current practice in the UK and reviewed the evidence for each intervention. METHODS: An online semi-structured questionnaire was emailed to all units registered on the British Paediatric Neurosurgery Group Mailing List. The survey consisted of 18 questions designed to establish the status quo in the management of nPHH, including preferred temporising procedure, factors guiding the timing of intervention and willingness to participate in a prospective study...

BACKGROUND: Primary intraventricular meningiomas (IVMs) make up 0.5-5% of all intracranial meningiomas and represent one of the most challenging lesions in neurosurgery. METHODS: Between 1990 and 2013, 42 patients (30 female, 12 male, mean age of 43.6 years) underwent the resection of their IVM. The removal was performed by posterior-parietal approach in 19 of the 40 lateral ventricle tumors, and one in the third ventricle meningioma. The transcallosal approach was used for three meningiomas, while other lesions underwent temporal (7 cases) and temporo-parietal approaches (12 pts) respectively...

The research evidence in the realm of surgery is expanding at a rapid pace, and thus corresponds with an increasing need to critically appraise and synthesize the available literature. Particularly in fields such as spine surgery, neurosurgery and orthopedics which traditionally have little Class I randomized clinical data, reviews are important to pool the available evidence on clinical questions which are otherwise difficult to answer. Whilst systematic reviews and meta-analyses have the potential to provide critical and updated surgical evidence to guide clinical decisions, poorly performed analyses and misinterpretation of such reviews may have a detrimental effect on patient care and outcomes...

Surgical resection is typically the first line of treatment for gliomas. However, the neurosurgeon faces a major challenge in achieving maximal resection in high-grade gliomas as these infiltrative tumors make it difficult to discern tumor margins from normal brain with conventional white-light microscopy alone. To aid in resection of these infiltrative tumors, fluorescence-guided surgery has gained much popularity in intraoperative visualization of malignant gliomas, with 5-aminolevulinic acid (5-ALA) leading the way...

BACKGROUND: Pediatric low-grade gliomas (LGGs) account for approximately half of all pediatric central nervous system tumors. The low-grade gliomas' first line of treatment is gross total resection. However, when gross total resection is not possible, options for adjuvant therapy are limited. MRI-guided laser ablation (magnetic resonance-guided laser interstitial thermal therapy (MRgLITT)) offers a new option for treatment in selected cases. We present a description of the current MRgLITT technology and an exemplary case-series review of our experience in its use in LGGs...

BACKGROUND: Tumors with epicenter in the thalamus occur in about 4 % of pediatric brain tumors. The histological diagnosis is mainly gliomas. Among them, low-grade glioma (LGG) constituted of a significant entity of the tumors (Cuccia et al., Childs Nerv Syst 13:514-521, 1997; Puget et al., J Neurosurg 106:354-362, 2007; Bernstein et al., J Neurosurg 61:649-656, 1984; Bilginer et al., Childs Nerv Syst 30:1493-1498, 2014). Since Kelly's report in 1989, >90 % resection of thalamic tumors were achieved in reported series (Ozek and Ture, Childs Nerv Syst 18:450-6, 2002; Villarejo et al...

INTRODUCTION: Over the past decade, the reluctance to operate in eloquent brain areas has been reconsidered in the light of the advent of new peri-operative functional neuroimaging techniques and new evidence from neuro-oncology. To maximise tumour resection while minimising morbidity should be the goal of brain surgery in children as much as it is in adults, and preservation of brain functions is critical in the light of the increased survival and the expectations in terms of quality of life...

INTRODUCTION: The pineal region is a deep-seated part of the brain surrounded by highly eloquent structures. Differential diagnosis of space-occupying lesions in this region encompasses pineal gland cysts, pineal gland tumours, metastases, germ cell tumours, meningiomas, gliomas, hemangioblastomas and neuroectodermal tumours. A treatment strategy is based mainly on tumour anatomical characteristics and histological type. Except germinatous tumours, a surgical excision is the treatment of choice...

China is currently the most populous and rapidly aging nation in the world. In the next few decades, China will have to increase the throughput, quality, and scope of its neurosurgical training programs in order to meet forecasted demand. Until recently, China lacked national education standards in neurosurgery that fostered imbalances in medical and pedagogical resources, quality of care, and education between different regions; and introduced significant heterogeneity in neurosurgical competency. In 2010, Shanghai implemented the first new standards-based comprehensive neurosurgery training program, which spans 7 years broken down into 2 blocks...

BACKGROUND: Jehovah's Witnesses (JW) are a Christian faith with > 1 million members in the United States who do not accept autologous blood transfusions. The optimal management of these patients undergoing neurosurgical procedures is not well defined. Here, we examined the feasibility and safety of JW undergoing neurosurgery in a blood management program. STUDY DESIGN AND METHODS: Sixty-eight JW patients including 23 males and 45 females (mean age 53 +/- 12 years) who underwent a variety of cranial (n=19) and spinal (n=49) neurosurgical procedures over a 5-year period were identified retrospectively and their hospital charts, anesthetic records and operative reports reviewed...
