Advances in virtual and augmented reality (AR) are having an impact on the medical field in areas such as surgical simulation. Improvements to surgical simulation will provide students and residents with additional training and evaluation methods. This is particularly important for procedures such as the endoscopic third ventriculostomy (ETV), which residents perform regularly. Simulators such as NeuroTouch, have been designed to aid in training associated with this procedure. The authors have designed an affordable and easily accessible ETV simulator, and compare it with the existing NeuroTouch for its usability and training effectiveness...

Flexible endoscopes have both a wide range of movement and a wide field of view and are thus widely used for endoscopic third ventriculostomy and biopsy. However, tumor resection using flexible endoscopes has scarcely been reported, likely owing to their single port, which has a diameter of 1.2-2.0 mm. Furthermore, flexible endoscopes do not allow some of the basic neurosurgical manipulations, especially sharp dissection with counter tension. Additionally, the position of the forceps and coagulators is fixed within the endoscope...

OBJECTIVE Although endoscopic third ventriculostomy (ETV) with choroid plexus cauterization (CPC) has gained increasing prominence in the management of hydrocephalus caused by intraventricular hemorrhage of prematurity, the rates of long-term shunt independence remain low. Furthermore, limited evidence is available to identify infants who might benefit from the procedure. The authors tested the hypothesis that elevated venous pressure that results from comorbid cardiac disease might predispose patients to ETV/CPC failure and shunt dependence...

PURPOSE: Massive hemorrhages pose a significant problem in intraventricular endoscopic surgeries. These hemorrhages have the potential to cause mortality and morbidity, particularly in excisional surgeries. Often, the bleeding can be controlled only by cauterization and liquid irrigation, due to the incongruity of the use of antihemorrhagic agents in the fluid. The final option to stop the massive bleeding is the dry-field maneuver. In this study, the effects and clinical results of the dry-field maneuver in bleeding control of a massive bleeding were investigated...

BACKGROUND: Novel methodologies providing realistic simulation of the neurosurgical operating room environment are currently needed, particularly for highly subspecialized operations with steep learning curves, high-risk profiles, and demands for advanced psychomotor skills. OBJECTIVE: To describe the development of a curriculum for using perfusion-based cadaveric simulation models in a "Mock Operating Room" for neurosurgical procedures. METHODS: At the USC Keck School of Medicine Fresh Tissue Dissection Laboratory between 2012 and 2016, 43 cadaveric specimens underwent cannulation of the femoral or carotid artery and artificial perfusion of the arterial system, and/or cannulation of the intradural cervical spine for intrathecal reconstitution of the cerebrospinal fluid (CSF) system...

Normal pressure hydrocephalus (NPH) is a chronic disorder caused by interrupted CSF absorption or flow. Generally, shunt placement is first option for NPH treatment. Due to complications of ventriculo-peritoneal (VP) shunt placement, endoscopic third ventriculostomy (ETV) can be considered as an alternative treatment option. Here we report the efficacy of ETV especially in old aged patients with normal pressure hydrocephalus. Total 21 old aged patients with communicating hydrocephalus with opening pressure, measured via lumbar puncture, less than 20cm H2O underwent ETV...

PURPOSE: Hydrocephalus-related symptoms are mostly improved after successful endoscopic third ventriculostomy (ETV). However, visual symptoms can be different. This study was focused on visual symptoms. We analyzed the magnetic resonance images (MRI) of the orbit and visual outcomes. METHODS: From August 2006 to November 2016, 50 patients with hydrocephalus underwent ETV. The male-to-female ratio was 33:17, and the median age was 61 years (range, 5-74 years). There were 18 pediatric and 32 adult patients...

BACKGROUND: External ventricular drain (EVD) placement is a common neurosurgical procedure used to control acute hydrocephalus and other neurosurgical complications. The infection and complication rates reported in the literature are highly variable, and iatrogenic factors determine the outcome of drain placement. We examined the impact of the setting of EVD placement (emergency department [ED] vs. intensive care unit [ICU] vs. operating room [OR]) and the experience of the operating surgeon on the infection rate, complication rate, EVD replacement, eventual placement of a ventriculoperitoneal shunt, and the need for further surgical intervention...

In the United Kingdom, ultrasound-guided external ventricular drain (EVD) insertion is becoming the standard of care to mitigate the morbidity associated with catheter malposition and multiple passes. Many neurosurgeons routinely use ultrasound to check the preinsertion trajectory, although real-time visualization of ventricular cannulation is preferable since minor deviations can be significant in patients with smaller ventricles, and live visualization further enables the catheter tip to be adjusted away from the choroid plexus...

OBJECTIVE Endoscopic third ventriculostomy with choroid plexus cauterization for the treatment of neonatal and infant hydrocephalus has gained popularity in the past decade. Identifying treatment failure is critically important. Results of a pilot study of 2 novel imaging markers seen on fast-sequence T2-weighted axial MRI showed potential clinical utility. However, the reliability of multiple raters detecting these markers must be established before a multicenter validation study can be performed. METHODS Two sets of de-identified single-shot T2-weighted turbo spin-echo axial images were prepared from scans of patients before and after they underwent endoscopic third ventriculostomy with choroid plexus cauterization between March 2013 and January 2016...

PURPOSE: Ventriculitis is a known complication during external CSF drainage in preterm infants with posthaemorrhagic ventricular dilatation. Staphylococci are most frequently isolated in device-associated ventriculitis, and hence, intraventricular vancomycin is a commonly used therapy. Our aim was to study the CSF vancomycin level pattern and drug safety in ventriculostomy access device infection in preterm infants less than 28 weeks gestation. METHODS: This single-centre, retrospective case series included seven infants with a median gestational age of 25 + 4 weeks (range 23 + 6 to 27 + 5 weeks)...
