The management of cerebrovascular disease has advanced considerably in 2015. Five randomized control trials have firmly established the role of endovascular thrombectomy for ischemic strokes due to large vessel occlusion. The randomized trial of intraarterial treatment for acute ischemic stroke (MR CLEAN) (Berkhemer et al. NEJM 2015;372:11-20) was the first of a series on the topic. There was a total of 5 randomized controlled trials published showing benefit in terms of functional outcomes at 90days for mechanical thrombectomy including the Endovascular Therapy for Ischemic stroke with perfusion-imaging selection (EXTEND IA) (Campbell et al...

BACKGROUND: The optimal timing of cranioplasty remains uncertain. OBJECTIVE: We hypothesized that the risk of infections following primary cranioplasty in adult patients who underwent craniectomies for non-infection related indications are no different when performed early or delayed. We tested this hypothesis in a prospective, multicentre, cohort study. METHODS: Data was collected prospectively from five neurosurgical centres in United Kingdom, Malaysia, Singapore and Bangladesh...

UNLABELLED: : Imaging is important in the evaluation of patients with degenerative disease and infectious processes. There are numerous conditions that can manifest as low back pain (LBP) or neck pain in a patient, and in many cases, the cause may be multifactorial. Clinical history and physical examination are key components in the evaluation of such patients; however, physical examination has variable sensitivity and specificity. Although studies have demonstrated that uncomplicated acute LBP and/or radiculopathy are self-limited conditions that do not warrant any imaging, neuroimaging can provide clear anatomic delineation of potential causes of the patient's clinical presentation...

Visual loss is a rare but potentially devastating postoperative complication of prone spinal surgery with a reported incidence of 0.017 to 0.1 percent. We present a case of post-operative bilateral visual loss in a patient who had a laminectomy in prone position under general anesthesia. A 17-year-old male patient with large syringomyelia extending from C2 - T2 level had a surgical procedure done under general anesthesia (GA) in prone position that lasted four hours. After the surgical procedure, the patient presented to the Ophthalmology Clinic of Princess Marina Hospital, with a complaint of visual loss of the right eye followed by left, of one week duration...

Reversible posterior leukoencephalopathy syndrome (RPLS) is characterized clinically by headache, altered mental status, abnormal visual perception and seizures. It is associated with neuroradiological findings characterized by reversible white matter abnormalities, predominantly in the parietal-occipital areas. Since the first description in 1996, it has been recognized in an increasing number of medical conditions, including hypertensive encephalopathy, eclampsia, and immunosuppressive treatment. The rapid resolution of clinical and neuroradiologic abnormalities suggests cerebral oedema, which is thought to result from impaired cerebrovascular autoregulation and endothelial injury...

OBJECTIVES: Awake craniotomy is a well-established procedure in surgery of intracranial tumors in eloquent areas. However, sufficiently standardized instruments for the assessment of sensory-motor function before, during and after the operation are currently lacking, despite their importance for evaluation of operative outcome. PATIENTS AND METHODS: To address this issue, we designed a standardized assessment tool (the "sensory-motor profile awake scale"; SMP-a)...

OBJECTIVE: The Sylvian fissure has been dissected through the frontal side of the superficial Sylvian veins with sacrifice of the tributaries of the frontal superficial Sylvian vein, which may lead to venous infarction. In addition, disturbed venous drainage makes the brain susceptible to brain retraction. Therefore, preservation of the vein is essential in modern neurosurgery to decrease morbidity. METHODS: We describe the technical nuances of Sylvian dissection with an emphasis on preserving the veins...

OBJECTIVE The comparative effectiveness of the 2 treatment options-surgical clipping and endovascular coiling-for unruptured cerebral aneurysms remains an issue of debate and has not been studied in clinical trials. The authors investigated the association between treatment method for unruptured cerebral aneurysms and outcomes in elderly patients. METHODS The authors performed a cohort study of 100% of Medicare fee-for-service claims data for elderly patients who had treatment for unruptured cerebral aneurysms between 2007 and 2012...

OBJECTIVES: Ventriculitis is an uncommon condition with a poor prognosis, especially when complicated by brain abscess. We compared the therapeutic efficacy of neuroendoscopic ventricular irrigation with those of conventional treatments such as ventricular drainage and continuous irrigation via a ventricular drain. PATIENTS AND METHODS: We retrospectively analyzed 14 consecutive patients treated for ventriculitis at our institution between 2001 and 2015. Included were the six patients treated with neuroendoscopic (NE) irrigation (NE group), which we adopted in 2011, and the eight patients treated before 2011 with conventional treatments (non-NE group)...

This report describes a reliable and simple technique for securing external ventricular drains (EVDs) to the scalp and avoiding pullout complications. The operative technique consists of fixing the drain between 2 hydrocolloid dressings and securing it with staples. A 10-year retrospective analysis of EVD pullout complications was performed in a series of 435 consecutive patients who were treated at a single institution. The EVD pullout complication rate was 0.4%. No complications related to the fixation technique were found...

OBJECTIVE Diffusion tensor imaging (DTI) has been shown to detect tumor invasion in glioblastoma patients and has been applied in surgical planning. However, the clinical value of the extent of resection based on DTI is unclear. Therefore, the correlation between the extent of resection of DTI abnormalities and patients' outcome was retrospectively reviewed. METHODS A review was conducted of 31 patients with newly diagnosed supratentorial glioblastoma who underwent standard 5-aminolevulinic acid-aided surgery with the aim of maximal resection of the enhancing tumor component...
