INTRODUCTION: To assess the early safety and efficacy of anterior cerebral artery (ACA) and anterior communicating artery (ACoA) aneurysm treatment with flow-diversion devices (FDDs), we performed a systematic review and meta-analysis for these aneurysms. EVIDENCE ACQUISITION: A literature search was performed by a reference librarian, and, after screening, eight case series were included for meta-analysis. We estimated from each study the cumulative incidence (event rate) and 95% confidence interval (CI) for each outcome...

Mechanical thrombectomy has become the stand of care for patients with large vessel occlusions, yet major improvements in thrombectomy speed, efficacy, and completeness can still be achieved. High rates of clot fragmentation and failure to remove the clot resulting in poor neurological outcomes suggest that in order to further advance the field of stroke intervention; we must turn our attention towards understanding the science of clot. Accurately identifying the composition of the occlusive clot prior to intervention could significantly influence the success of the revascularization strategy used to treat them...

BACKGROUND: Hypernatremia is one of the most common electrolyte disturbances following aneurysmal subarachnoid hemorrhage (aSAH) and has been correlated with increased mortality in single institution studies. We investigated this association using a large nationwide healthcare database. METHODS: We performed a retrospective analysis of adults between 2002 and 2011 with a primary diagnosis of aSAH using the Nationwide Inpatient Sample (NIS). Patients were grouped according to whether or not an inpatient diagnosis of hypernatremia was present...

BACKGROUND: Recent clinical trials demonstrated the efficacy of thrombectomy for ischemic stroke against acute large vessel occlusion (LVO). To overcome the problem with excessive examination time for diagnosis of cerebral perfusion and/or the use of contrast agent to determine penumbra, we adopted a new magnetic resonance imaging technique named Acute Stroke Assessment using rapid Pseudo-continuous arterial spin labeling (ASAP-ASL) method. METHODS: The study included healthy volunteers and clinical patients...

BACKGROUND: With increasing life expectancy and increasing demands on quality of life more spinal meningiomas will limit quality of life in elderly in the coming decades. We investigated whether elderly can improve neurologically and gain self-dependence postoperatively. METHODS: Medical records of consecutive spinal meningioma patients from 2004 - 2015 were retrospectively analyzed. Age, gender, preoperative duration and quality of symptoms, pre- and postoperative McCormick score, Karnofsky Performace Status (KPS), American Society of Anesthesiologists Physical Status (ASA), modified Clinical Scoring System (mCSS) and tumor characteristics were included...

BACKGROUND: With increased experience and the availability of new technical instrumentations, the surgical endoscopic indications for lumbar spinal pathologies have moved from simple prolapsed disk to canal stenosis. The available endoscopes come in two different sizes (10 mm and 6.3 mm in diameter); however, one is too bulky to use inside the spinal canal and the other is too small to achieve a fast bone decompression. METHODS: In order to overcome such problems, we developed and used a different surgical technique called: Double Endoscopic Technique...

The treatment of gliomas became more sophisticated during the last decades. As by now, adjuvant treatment after maximum safe resection is considered an important and effective treatment strategy in most gliomas, yet the decision is based on several factors. This review summarizes the available evidence for the current adjuvant treatment algorithms with a focus on the impact on the survival of glioma patients. The review is based on the current guidelines, but it also includes new insights which have not yet been included into the official guidelines...

BACKGROUND: Evidence-based indications for intracranial pressure (ICP) monitoring in patients with traumatic brain injury (TBI) are lacking. The aim of this study was to analyze the main factors that guided the decision-making of invasive ICP monitoring in a large cohort of TBI patients from our institution. METHODS: This is a retrospective, single centre, observational study including adult TBI patients consecutively admitted to our NeuroIntensive Care Unit over 20 years...

BACKGROUND: A comparison of clinical and radiological outcomes after two different variants of open door laminoplasty for cervical spondylotic myelopathy (CSM) is described. METHODS: Fifty-five patients underwent cervical laminoplasty for CSM. Between 2005 to 2009, 32 patients underwent open-door laminoplasty (Group A) performed with a monolateral exposure with contralateral "green stick" laminar fracture. A technical variant consisting in bilateral exposure, spinous process removal and symmetrical muscular closure was applied in the other 23 (Group B), from 2009 to 2016...

INTRODUCTION: Decompressive craniectomy (DC) to control refractory intracranial hypertension in patients with traumatic brain injury (TBI), has been listed as possible but controversial therapeutic approach in the latest version of TBI management guidelines. This study aimed to perform a systematic review and meta-analysis on efficacy and safety of DC compared to standard care in TBI patients. EVIDENCE ACQUISITION: A database search from 2011 to 2017 was conducted to identify studies pertinent to DC compared to standard care after TBI...

BACKGROUND: Meningiomas are the most common primary intracranial tumor, arising from different locations, including the skull base. Despite advances in adjuvant treatments, surgical resection remains the main and best treatment for meningiomas. New surgical strategies, such as the endoscopic endonasal approach, have greatly contributed in achieving maximum and total safe resection, preserving the patient's neurological function. METHODS: Based on the senior authors large experience and a review of the current literature, we have compiled this paper...

The tremendous advances in endoscopic skull base surgery added a new set of intricate less invasive approaches to the neurosurgical armamentarium. The new generations of neurosurgeons face the challenge of adopting the ever-changing technology and quickly learning modern surgical techniques beyond the traditional neurosurgery comfort zone. The future skull base surgeon must be well trained and knowledgeable in all surgical portals to the skull base in order to select the safest, least invasive, most direct approach that offers the optimum exposure to handle a complex skull base pathology...

BACKGROUND: In many clinical trials endovascular procedures are suggested as the treatment of choice for aneurysmal Subarachnoid Hemorrhage (aSAH) whenever possible. However, in clinical practice this management is often controversial. The aim of this study is to analyze factors involved in this decision. METHODS: Our study included 317 consecutive cases of aSAH between 2010 and 2016, assessing clinical and neuroradiological features to evaluate their role in this choice...

BACKGROUND: Risk factors for incidental durotomies are good documented claimed from some authors the degree of invasiveness as a direct risk factor on this serious complication. We compared the rate of incidental durotomies and its dependence from the degree of invasiveness. METHODS: The German Spine Registry could document 6016 surgeries for lumbar spinal canal stenosis, n= 2539 microsurgical decompression and n= 2371 open decompression with stabilization. RESULTS: Both groups were identical concerning age and sex of patients: mean age 77,1 ± 1,60, female 58%, male 32%...

Brain mapping techniques (intraoperative neurophysiology and intraoperative neuropsychology) represent the gold standard in glioma surgery; these techniques have been proven to be the gold standard in glioma resection. From the introduction of MRI in clinical routine, several advanced applications have been developed like functional MRI and tractography based on diffusion imaging. Both techniques have application in glioma surgery. The fMRI allows to identify cortical areas related to a specific function, DTI allow to reconstruct a model of the sub-cortical connectivity...
