Glioblastoma (GBM) is the most common primary intracranial neoplasia, and is characterized by its extremely poor prognosis. Despite maximum surgery, chemotherapy, and radiation, the histological heterogeneity of GBM makes total eradication impossible, due to residual cancer cells invading the parenchyma, which is not otherwise seen in radiographic images. Even with gross total resection, the heterogeneity and the dormant nature of brain tumor initiating cells allow for therapeutic evasion, contributing to its recurrence and malignant progression, and severely impacting survival...

Primary intracerebral hemorrhage (ICH) is a common, devastating disease that lacks an effective specific treatment. Mortality is high, functional outcomes are poor, and these have not substantially changed for decades. There is, therefore, considerable opportunity for advancement in the management of ICH. In recent years, a significant amount of research has begun to address this gap. This article is aimed at updating neurologists on the most clinically relevant contemporary research.

OBJECTIVE: Advances in video and fiber optics since the 1990s have led to the development of several commercially available high-definition neuroendoscopes. This technological improvement, however, has been surpassed by the smartphone revolution. With the increasing integration of smartphone technology into medical care, the introduction of these high-quality computerized communication devices with built-in digital cameras offers new possibilities in neuroendoscopy. The aim of this study was to investigate the usefulness of smartphone-endoscope integration in performing different types of minimally invasive neurosurgery...

BACKGROUND: Chronic subdural hematoma (SDH) is a particularly challenging pathology due to high recurrence rates (2%-37%) and complex medical comorbidities that tend to afflict the patient population. Recently, there have been several case series published describing the use of middle meningeal artery (MMA) embolization as an alternative to surgery for treatment of new or recurrent chronic SDH. OBJECTIVE: To describe our first 60 cases of MMA embolization for chronic SDH...

The care of patients with traumatic brain injury can be one of the most challenging and rewarding aspects of clinical neurocritical care. This article reviews the approach to unique aspects specific to the care of this patient population. These aspects include appropriate use of sedation and analgesia, and the principles and the clinical use of intracranial monitors. Common clinical challenges encountered in these patients are also discussed, including the treatment of intracranial hypertension, temperature management, and control of sympathetic hyperactivity...

Optimizing outcomes after aneurysmal subarachnoid hemorrhage remains a challenge for neurosurgeons and neurointensivists alike. Although we have learned a lot about the pathophysiology of this disease, many clinical questions are still unanswered. In this review, the authors discuss some of these questions, including the current diagnostic value of lumbar puncture in patients with negative computed tomography scans, the treatment value of blood pressure reduction and antifibrinolytics for prevention of early rebleeding, the indication for antiseizure medications, the optimal management of hydrocephalus and intracranial pressure, the role of clipping, and the options for diagnosis and treatment of delayed cerebral ischemia...

Acute spontaneous intracerebral haemorrhage is a life-threatening illness of global importance, with a poor prognosis and few proven treatments. As a heterogeneous disease, certain clinical and imaging features help identify the cause, prognosis, and how to manage the disease. Survival and recovery from intracerebral haemorrhage are related to the site, mass effect, and intracranial pressure from the underlying haematoma, and by subsequent cerebral oedema from perihaematomal neurotoxicity or inflammation and complications from prolonged neurological dysfunction...

OBJECTIVEChronic subdural hematoma (CSDH) is commonly encountered in neurosurgical practice. However, surgical evacuation remains complicated by a high rate of reoperation. The optimal surgical approach to reduce the reoperation rate has not been determined. In the current study, the authors evaluated the prognostic value of clinical and radiographic factors to predict reoperation in the context of CSDH.METHODSA retrospective review of 325 CSDH patients admitted to an academic medical center in the United States, between 2006 and 2016, was performed...

PURPOSE OF REVIEW: We review the current evidence for medical and surgical treatments of spontaneous intracerebral hemorrhage (ICH). RECENT FINDINGS: Therapy with hemostatic agents (e.g. factor VIIa and tranexamic acid) if started early after bleeding onset may reduce hematoma expansion, but their clinical effectiveness has not been shown. Rapid anticoagulation reversal with prothrombin concentrates (PCC) plus vitamin K is the first choice in vitamin K antagonist-related ICH...

OBJECTIVE: Decompressive craniectomy (DC) lowers intracranial pressure and improves outcomes in patients with malignant middle cerebral artery stroke; yet, its usefulness in intracerebral hemorrhage (ICH) is unclear. The authors sought to assess the preliminary utility of decompressive hemicraniectomy (DHC) without clot evacuation in patients with deep-seated supratentorial ICH. PATIENTS AND METHODS: Patients with deep seated spontaneous ICH who were admitted to the Golestan Hospital, of Ahvaz, from November 2014 to February 2016, were prospectively enrolled in this study...

Spinal infection (SI) is defined as an infectious disease affecting the vertebral body, the intervertebral disc, and/or adjacent paraspinal tissue and represents 2-7% of all musculoskeletal infections. There are numerous factors, which may facilitate the development of SI including not only advanced patient age and comorbidities but also spinal surgery. Due to the low specificity of signs, the delay in diagnosis of SI remains an important issue and poor outcome is frequently seen. Diagnosis should always be supported by clinical, laboratory, and imaging findings, magnetic resonance imaging (MRI) remaining the most reliable method...

Central nervous system infections can be complications of neurosurgical procedures or can occur spontaneously, and occasionally lead to devastating neurological complications, increased rate of mortality, and lengthier stays in the hospital, subsequently increasing costs. The use of intrathecal antibiotics to bypass the blood brain barrier and provide effective concentrations to the central nervous system has been described as an adjunct treatment option. However, the regimens of antibiotics utilized intrathecally have not been standardized...

OBJECTIVEDe novo seizure following craniotomy (DSC) for nontraumatic pathology may adversely affect medical and neurological outcomes in patients with no history of seizures who have undergone craniotomies. Antiepileptic drugs (AEDs) are commonly used prophylactically in patients undergoing craniotomy; however, evidence supporting this practice is limited and mixed. The authors aimed to collate the available evidence on the efficacy and tolerability of levetiracetam monotherapy and compare it with that of the classic AED, phenytoin, for DSC...

BACKGROUND: Open microsurgical clipping of unruptured intracranial aneurysms has long been the gold standard, yet advancements in endovascular coiling techniques have begun to challenge the status quo. OBJECTIVE: To compare endovascular coiling with microsurgical clipping among adults with unruptured middle cerebral artery aneurysms (MCAA) by conducting a meta-analysis. METHODS: A systematic search was conducted from January 2011 to October 2015 to update a previous meta-analysis...

OBJECTIVE: Ventriculoperitoneal (VP) shunt is the most common neurosurgical procedure to treat obstructive and communicating hydrocephalus, but failures are frequent. The most common causes of shunt failure are malpositioning and obstruction of the ventricular catheter by debris or blood clothes. The knowledge of the relationship between ventricular catheter tip position, etiology of hydrocephalus and patient's age with shunt malfunction may be useful to avoid shunt failure. PATIENTS AND METHODS: We retrospectively analyze 89 adult patients affected by obstructive and communicating hydrocephalus operated with Ventriculoperitoneal shunt at our Institute...
