A male neonate was referred to our hospital for the treatment of myelomeningocele and hydrocephalus related to Chiari malformation type 2. After the placement of ventriculoperitoneal (VP) shunt for hydrocephalus, an intracranial cyst, which was asymptomatic at first, expanded and caused clinical symptoms due to increased intracranial pressure. The expansion of the cyst was confirmed dominantly in the right lateral ventricle where the VP shunt was inserted. Intraoperative findings through a neuroendoscope suggested that the expanded cyst was an isolated lesion...

Neuroendoscopy is now considered to be a minimally invasive surgical approach for expanding lesions bulging into the ventricle, and it is also considered to be a relevant tool for performing biopsy procedures, fenestration of cystic walls, or for performing tumor removal in selected cases. Furthermore, the use of neuroimaging and the accurate follow-up of brain tumor patients have allowed the documentation of tumoral and pseudotumoral cystic areas that cause the obstruction of cerebrospinal fluid (CSF) pathways...

The aim of the study was to explore keyhole approach and dura suture in the neuroendoscopic treatment for hydrocephalus.Twelve cases of hydrocephalus patients who were treated with neuroendoscope by this approach were analyzed retrospectively from April 2015 to April 2016 in our department. The basic steps of this procedure was using drill and milling cutter to form a small bone flap instead of burr hole, and then making a cruciate incision on the dura. After endoscopic third ventriculostomy or endoscopic third ventriculostomy + ventriculocystostomy finished, dura was sutured and the bone flap was reset...

Intraventricular cavernomas (IVCs) are extremely infrequent and only occur in 2.8 to 10% of patients with cerebral cavernomas. We describe three IVC cases and briefly review previously documented IVC cases in PubMed. Among 136 IVC cases, the mean age of the patients was 36.5 years; the male-to-female ratio was 0.8. The most frequent location was the lateral ventricle (52.6%), and most of the clinical symptoms (74%) were related to mass effects on adjacent brain tissues. Intraventricular hemorrhage occurred in 22...

BACKGROUND: Pyogenic cerebral ventriculitis is a debilitating form of intracranial infection with an unfavorable outcome due to lack of experience in surgical management. OBJECTIVE: To study retrospectively a group of pyogenic cerebral ventriculitis patients managed by neuroendoscopic surgery (NES). METHODS: The standard intraventricular protocols of NES to treat this disease included 1 or more of the following: (1) to obliterate debris, (2) to observe evidence of microbial infection, (3) to perform septomy, (4) to incise the septation, or (5) to monitor catheter insertion...

BACKGROUND: The relationship between the use of an endoscope during ventriculoperitoneal shunt (VPS) procedures and infection is still poorly defined. The present work sought to analyze whether or not the simultaneous use of an endoscope could in fact increase the infection rate of VPS procedures. METHODS: In a study of 438 VPS procedures, an endoscope was used in 49 (11.2%) cases and was not used in 389 (88.8%). The infection rates in these two main groups were then calculated and compared...

Epidermoid cyst is a benign and congenital lesion of ectodermal origin. Traditionally, microsurgical techniques are used to treat these lesions, and their occurrence in the third ventricle is rare. Here, the authors describe report a case of epidermoid cyst in the third ventricle that presented with signs and symptoms of intracranial hypertension, which was treated safely and effectively using neuroendoscopic surgery.

: Although endoscopic techniques have many advantages including improved visualizations and magnification., these are also associated with limitations. Objective of this study is to discuss practical aspects that can reduce complications after endoscopic procedures, and their management. Review is based on personal experience of more than 2000 neuroendoscopic procedures performed by the senior author. Topic search was made on PubMed using Neuroendoscopy, complications and neuroendoscopy, complication avoidance and neuroendoscopy, endoscopic neurosurgery, and minimally invasive neurosurgery...

BACKGROUND: Presurgical planning allows anticipating intraoperative difficulties, increasing efficiency, and reducing risks. Neuroendoscopy is a minimally invasive technique whose related complications have been focused on cortical function and surface vessels injury. However, white matter disruption has been insufficiently acknowledged. OBJECTIVE: To present a new surgical planning method based on diffusion tensor image that allows quantifying subcortical transgression and optimizing neuroendoscopic trajectories...

INTRODUCTION: Intraventricular cavernous angiomas are rare pathological entities, and those located at the foramen of Monro are even rarer. We herein present a case of cavernous angioma at the foramen of Monro that was successfully treated by neuroendoscope-assisted surgical removal, and review the relevant literature. CASE PRESENTATION: A 65-year-old woman had experienced headache and vomiting for 10 days before admission to another hospital. Magnetic resonance imaging (MRI) showed a mass at the foramen of Monro, and obstructive hydrocephalus of both lateral ventricles...

BACKGROUND: Endoscopic third ventriculostomy (ETV) has become one of the most common neuroendoscopic procedures. METHODS: In this article, we will review the major milestones in the history of ETV development from its early use by Walter Dandy to the techniques currently employed with advanced technology. CONCLUSIONS: ETV has become an important technique in the armamentarium of the neurosurgeon. From a meager beginning with few applications, our knowledge of long-term outcomes has evolved...

BACKGROUND: Isolated hypothalamic-pituitary Langerhans cell histiocytosis (HPLCH) is very rare. We investigated the clinicopathological characteristics, endocrine function changes, BRAF(V600E) mutations and treatments of isolated HPLCH. METHODS: We identified seven patients with isolated HPLCH by reviewing the clinical and pathological files in our hospital from 2007 to 2015. The clinical characteristics of the seven patients were retrospectively reviewed, especially the endocrine function changes...

AIM: Neonatal intraventricular hemorrhage (IVH) usually results in posthemorrhagic hydrocephalus (PHH). This multicenter study describes the approach of early neuroendoscopic ventricular irrigation for the treatment of IVH/PHH and compares the results with the cases that have been initially treated only with conventional temporary CSF diversion techniques. MATERIAL AND METHODS: The data of total 74 neonatal PHH cases that have been treated at three pediatric neurosurgery centers were retrospectively analyzed...

BACKGROUND: Intraparenchymal cysts without communication to the ventricles or the subarachnoid space are named ependymal or epithelial cysts. The estimated ratio of their incidence compared with arachnoid cysts is 1:10. Neurologic deficit can occur when the cyst exerts mass effect on its surroundings. We evaluated the success rate of endoscopic fenestration of intracranial ependymal cysts. METHODS: Our prospectively maintained endoscopy database was screened for all cases of ependymal cysts...

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...
