Decompressive Craniectomy versus Craniotomy for Acute Subdural Hematoma.

Background: Traumatic acute subdural hematomas frequently warrant surgical evacuation by means of a craniotomy (bone flap replaced) or decompressive craniectomy (bone flap not replaced). Craniectomy may prevent intracranial hypertension, but whether it is associated with better outcomes is unclear.

Methods: We conducted a trial in which patients undergoing surgery for traumatic acute subdural hematoma were randomly assigned to undergo craniotomy or decompressive craniectomy.

Trial of Dexamethasone for Chronic Subdural Hematoma.

Background: Chronic subdural hematoma is a common neurologic disorder that is especially prevalent among older people. The effect of dexamethasone on outcomes in patients with chronic subdural hematoma has not been well studied.

Methods: We conducted a multicenter, randomized trial in the United Kingdom that enrolled adult patients with symptomatic chronic subdural hematoma.

External Validation of Scoring Models to Predict Shunt Insertion after Aneurysmal Subarachnoid Hemorrhage.

Background: The current study is an external validation of 4 scoring models proposed in the literature for predicting ventriculoperitoneal shunt insertion after aneurysmal subarachnoid hemorrhage (aSAH) using retrospective patient data from Sheffield Teaching Hospital (STH).

Methods: Data were collected on various demographics, and patients were individually scored using the 4 scoring models. Models were compared with each other using receiver-operator characteristic curves.

Thirty-Day Mortality and Survival in Elderly Patients Undergoing Neurosurgery.

Objectives: With an aging population and advances in neuroanesthesia and critical care, an increasing subgroup of elderly patients have been undergoing neurosurgery. Of particular relevance is the cohort aged >80 years. The aim of the present study was to investigate the 30-day mortality and survival in this cohort after emergency and elective neurosurgery.

Compartmentalisation of the inflammatory response following aneurysmal subarachnoid haemorrhage.

Introduction: There is some evidence to suggest that a systemic and central nervous system (CNS) inflammatory response occurs following aneurysmal subarachnoid haemorrhage (aSAH) which may be related to the pathophysiology of early brain injury and delayed ischaemic neurological deficit (DIND). The aim of this study was to measure inflammatory mediator levels in plasma and cerebrospinal fluid (CSF) in the days following aSAH and to determine their association with aSAH, DIND and clinical outcome.

Material And Methods: Plasma and CSF samples were obtained prospectively from patients with aSAH on days 1-3, 5, 7 and 9 and profiled for interleukin (IL)-1α, IL-1β, IL-4, IL-6, IL-8, IL-10, IL-15, IL-17, IL-18, macrophage chemotactic protein (MCP)-1, vascular endothelial growth factor (VEGF) and tumour necrosis factor (TNF)-α.

Dex-CSDH randomised, placebo-controlled trial of dexamethasone for chronic subdural haematoma: report of the internal pilot phase.

The Dex-CSDH trial is a randomised, double-blind, placebo-controlled trial of dexamethasone for patients with a symptomatic chronic subdural haematoma. The trial commenced with an internal pilot, whose primary objective was to assess the feasibility of multi-centre recruitment. Primary outcome data collection and safety were also assessed, whilst maintaining blinding.

Correction to: Dexamethasone for adult patients with a symptomatic chronic subdural haematoma (Dex-CSDH) trial: study protocol for a randomised controlled trial.

After publication of the original article [1], the authors notified that that one of the BNTRC institutional collaborator names was misspelled.

Dexamethasone for adult patients with a symptomatic chronic subdural haematoma (Dex-CSDH) trial: study protocol for a randomised controlled trial.

Background: Chronic subdural haematoma (CSDH) is a common neurosurgical condition, typically treated with surgical drainage of the haematoma. However, surgery is associated with mortality and morbidity, including up to 20% recurrence of the CSDH. Steroids, such as dexamethasone, have been identified as a potential therapy for reducing recurrence risk in surgically treated CSDHs.

Low-Grade Glioma with Foci of Early Transformation Does Not Necessarily Require Adjuvant Therapy After Radical Surgical Resection.

Background: Low-grade glioma (LGG) is a slow-growing tumor often found in young adults with minimal or no symptoms. As opposed to true low-grade lesions such as dysembryoplastic neuroepithelial tumors, they are associated with continuous growth and inevitable malignant transformation.

Methods: Case series of patients who have had en bloc resection of LGG with foci of anaplasia found embedded within the tumor specimen and not at margins.

Safety of Superior Petrosal Vein Sacrifice During Microvascular Decompression of the Trigeminal Nerve.

Background: Microvascular decompression (MVD) is a safe and effective treatment for trigeminal neuralgia. Cerebellar venous infarction is a complication associated with surgical sacrifice of the superior petrosal vein (SPV). The SPV intervenes between the trigeminal nerve and the surgeon.

Self-perceived health status following aneurysmal subarachnoid haemorrhage: a cohort study.

Objective: The objective of the study was to assess the long-term self-reported health status and quality of life (QoL) of patients following an aneurysmal subarachnoid haemorrhage (ASAH) using a self-completed questionnaire booklet.

Design: A two-cohort study.

Setting: A regional tertiary neurosurgical centre.

Fracture through fused cervical segments following trauma in a patient with Klippel-Feil syndrome.

Klippel-Feil syndrome (KPS) is a congenital spinal deformity characterised by the presence of at least one fused cervical segment. We report an unusual case of a fracture through fused cervical segment in a patient with KPS, who presented with quadriparesis and progressed on to develop respiratory failure and quadriplegia and who had a successful outcome following surgery. To the best of our knowledge, fracture through fused cervical segments in a Klippel-Feil patient has not been reported previously and this case report extends the spectrum of injuries seen in patients with KPS.

Ventriculoperitoneal shunt 30-day failure rate: a retrospective international cohort study.

Background: With the need for transparency of surgical results, 30-day outcome measures have become increasingly important. Ventriculoperitoneal (VP) shunt failure is a substantial burden to patients and health care systems.

Objective: This study introduces the 30-day VP shunt failure rate as a possible barometer of surgical outcome and demonstrates its use in a national (United Kingdom [UK]) study and makes comparison with 2 published randomized, controlled trials (RCT).

Comparison of acrylic and titanium cranioplasty.

Introduction: There are many indications for cranioplasty with an increasing incidence partly attributable to an increase in decompressive craniectomy following trauma and stroke. The aim of this study was to compare the survival of acrylic and titanium cranioplasties used in our department.

Materials And Methods: Retrospective cohort study of 126 patients who underwent cranioplasty between 1997 and 2007.

Lumbar drainage of cerebrospinal fluid after aneurysmal subarachnoid hemorrhage: a prospective, randomized, controlled trial (LUMAS).

Background And Purpose: A single-center prospective randomized controlled trial has been conducted to determine if lumbar drainage of cerebrospinal fluid after aneurysmal subarachnoid hemorrhage reduces the prevalence of delayed ischemic neurological deficit and improves clinical outcome.

Methods: Patients with World Federation of Neurological Surgeons Grade 1 to 3 aneurysmal subarachnoid hemorrhage and modified Fisher Grades 2, 3, 4, and 3+4 were randomized to either the study group of standard therapy plus insertion of a lumbar drain or the control group of standard therapy alone. The primary outcome measure was the prevalence of delayed ischemic neurological deficit.

Case series of atypical high flow arterio-venous malformations in children.

Arteriovenous malformations (AVM) constitute a clinically significant form of vascular malformations in children. We present three cases of paediatric AVMs that demonstrated unusual features of high flow and significant shunting of blood without a clearly demonstrable nidus. Venous malformations were associated with the lesions.

The Isadora syndrome: a case report of cervical, oesophageal and tracheal transection in a go-karting accident.

We report a case of cervical spine, tracheal and oesophageal trauma from a go-karting injury caused by the patient's scarf catching in the vehicle's wheel. We discuss the significance of the pre-hospital and operative management of this potentially life-threatening injury by a multi-specialty surgical team. The importance of health and safety issues in recreational sports is highlighted in view of the increasing incidence of cervical spine trauma over past two decades.

A review of delayed ischemic neurologic deficit following aneurysmal subarachnoid hemorrhage: historical overview, current treatment, and pathophysiology.

Delayed ischemic neurologic deficit (DIND) is a serious and poorly understood complication of aneurysmal subarachnoid hemorrhage. Although advances in treatment have improved prognosis for these patients, long-term clinical outcomes remain disappointing. Historically, angiographic vasospasm was thought to result in a DIND, although an increasing body of evidence suggests that this is an oversimplification, because interventions that have effectively targeted angiographic vasospasm have not improved outcome.

A comparison of the outcome of aneurysmal subarachnoid haemorrhage before and after the introduction of an endovascular service.

There has been a rapid change from predominantly surgical to endovascular treatment of ruptured intracranial aneurysms giving the opportunity to assess change in patient outcome during this transition. We identified and followed 139 patients with subarachnoid haemorrhage (SAH) treated in the year prior to (group 1) and following (group 2) the introduction of an endovascular service in a retrospective, cross-sectional study. A total of 78.

Assessment of zero drift in the Codman intracranial pressure monitor: a study from 2 neurointensive care units.

Objective: Intraparenchymal monitoring devices play an important role in the daily management of head injury and other critically ill neurosurgical patients. Although zero drift data exist for the Camino system (Camino Laboratories, San Diego, CA), only in vitro data exist for the Codman system (Codman and Shurtleff, Inc., Raynham, MA).

Serum albumin level as a predictor of outcome in traumatic brain injury: potential for treatment.

Background: Serum albumin level is correlated with outcome in various clinical situations. Albumin has multiple physiologic properties that could be beneficial in brain injury. The Lund therapy for elevated intracranial pressure uses albumin as part of its protocol and demonstrates favorable outcome.

Endoscopic biopsy during third ventriculostomy in paediatric pineal region tumours.

Objects: The goal of the study was to establish if endoscopic biopsy during third ventriculostomy contributes to morbidity in the management of paediatric pineal region tumours presenting with hydrocephalus.

Materials And Methods: This study was a retrospective descriptive study in patients less than 18 years of age who have presented with a pineal region tumour between 2000 and 2006. Data were obtained from case notes.

Patients with autosomal-recessive osteopetrosis presenting with hydrocephalus and hindbrain posterior fossa crowding.

Osteopetrosis is a heterogeneous group of disorders characterized by abnormal bone sclerosis. As a result, patients often require input regarding various neurological complications. Although autosomal-recessive osteopetrosis has been associated with hydrocephalus, it has not been linked to hindbrain abnormalities.
