Objective To compare the resolution rate of hydrocephalus after endoscopy (predominantly endoscopic third ventriculostomy [ETV]) using flexible endoscopes during a 5-year period in patients with a permeable and a nonpermeable subarachnoid space (SAS). Material and Methods We conducted a retrospective cohort study of the videos and records of 150 hydrocephalic patients chosen randomly who underwent ETV (and other endoscopic procedures) with a flexible endoscope. The patients were classified into two groups based on the neuroendoscopic findings...

This paper presents 800-μm thick, biocompatible sensing skins composed of arrays of pressure sensors. The arrays can be configured to conform to the surface of medical instruments so as to act as disposable sensing skins. In particular, the fabrication of cylindrical geometries is considered here for use on endoscopes. The sensing technology is based on polydimethylsiloxane synthetic silicone encapsulated microchannels filled with a biocompatible salt-saturated glycerol solution, functioning as the conductive medium...

BACKGROUND: Conventionally, patients suffering a massive intraventricular hemorrhage have undergone external ventricular drainage. However, long-term or repeated drainage increases the risk of complications due to infections or shunt dependency. Neuroendoscopic surgery may offer some advantages over more conventional procedures. METHODS: Thirteen patients suffering intraventricular hematoma associated with intracerebral hemorrhage, treated in our hospital between April 2011 and March 2014, were reviewed retrospectively...

OBJECTIVE: Placement of intraventricular catheters in oncology patients can be associated with morbidity given their small to slit-like ventricles and underlying hematologic disorders. We studied the accuracy of placing Ommaya reservoirs using neuronavigation and a flexible neuroendoscope to verify catheter positioning. METHODS: Ommaya reservoirs placed in 25 oncology patients between 2013 and 2015 were retrospectively reviewed. 25 ventricular catheters were placed using the AxiEM stealth frameless neuronavigation system and a flexible neuroendoscope...

A 70-year-old man presented to our hospital because of difficulty with discrete movement of the right upper limb and dysarthria. Computed tomography(CT)of the head revealed a chronic subdural hematoma(CSDH)on the left side. The patient underwent single burr-hole irrigation and drainage on the same day. In addition to the burr hole, a cross-shaped dural incision was made which revealed a thick outer membrane and solidified hematoma. We removed as much of the clotted hematoma as possible using a curved suction tube under neuroendoscopy...

OBJECTIVE Rigid endoscopes enable minimally invasive access to the ventricular system; however, the operative field is limited to the instrument tip, necessitating rotation of the entire instrument and causing consequent tissue compression while reaching around corners. Although flexible endoscopes offer tip steerability to address this limitation, they are more difficult to control and provide fewer and smaller working channels. A middle ground between these instruments-a rigid endoscope that possesses multiple instrument ports (for example, one at the tip and one on the side)-is proposed in this article, and a prototype device is evaluated in the context of a third ventricular colloid cyst resection combined with septostomy...

Neurocysticercosis is thought to be the most common helminthic infection of the central nervous system and its epidemiology is changing due to increasing travel and migration. Evidence to guide management of the intraventricular form is limited. We aimed to review the clinical presentation, diagnosis and treatment of intraventricular neurocysticercosis with reference to two recent cases seen at our institution. The intraventricular variant of neurocysticercosis is less common than parenchymal disease and usually presents with acutely raised intracranial pressure and untreated it progresses rapidly with high mortality...

A 19-year-old Caucasian male presented with complaints of headaches and syncope. Suspicion of hydrocephalus prompted computed tomography (CT) and magnetic resonance imaging (MRI), which revealed pineal and suprasellar prominences with diffuse, thick, nodular subependymal enhancement of the lateral and third ventricles. Based on imaging, the differential diagnosis consisted primarily of malignancy, such as lymphoma, with inflammatory and infectious etiologies not excluded. Cerebrospinal fluid (CSF) samples were non-specific, and neuroendoscopic tissue biopsy histologically confirmed the diagnosis of pure germinoma...

Colloid cysts are considered benign brain tumors and usually occur in the anterior third ventricle. The clinical presentation may be nonspecific and heterogeneous including headaches, visual changes, nausea, and vomiting. The symptomatology is frequently associated with the development of hydrocephalus. Neuroendoscopic removal is increasingly replacing open microsurgical approaches as the standard of care for the treatment of symptomatic colloid cysts of the third ventricle. We describe the case of a 42-year-old man who was found to have a colloid cyst of the third ventricle while undergoing evaluation for a dural arteriovenous fistula...

OBJECTIVE: To review the literature and analyze the efficacy and safety of 3 surgical methods (neuroendoscopic fenestration, microsurgical fenestration, and cystoperitoneal shunting) for middle cranial fossa arachnoid cysts (MCFACs). METHODS: We searched MEDLINE, PubMed, and Cochrane Central electronic databases and collected studies of patients with MCFACs treated with 1 of 3 surgical methods. Eligible studies reported the rate of clinical symptoms improvement (RCSI), rate of cyst reduction (RCR), rate of total complications (RTC), rate of short-term complications (RSTC), rate of long-term complications (RLTC), and other parameters...

OBJECTIVE At present, endoscopic treatment is advised as the first procedure in cases of suprasellar arachnoid cysts (SSCs) with hydrocephalus. However, the appropriate therapy for SSCs without hydrocephalus has not been fully determined yet because such cases are very rare and because it is usually difficult to perform the neuroendoscopic procedure in patients without ventriculomegaly given difficulties with ventricular cannulation and the narrow foramen of Monro. The purpose of this study was to find out the value of navigation-guided neuroendoscopic ventriculocystocisternostomy (VCC) for SSCs without lateral ventriculomegaly...
