Neuroendoscopic transventricular transchoroidal approach for access to the posterior zone of the third ventricle or pineal region.

The endoscopic transventricular transchoroidal approach facilitates entry into the posterior part of the third ventricle, allowing a visualization field from the foramen of Monro to the pineal region through this anatomical corridor. Combined surgery to treat the target lesion and possible endoscopic third ventriculostomy (ETV) can be performed through a single burr hole. A detailed description of this surgical technique is given, and a series of cases from our center is presented.

Analysis of complications in intraventricular neuroendoscopy in children: proposal for a standardization system.

Although intraventricular neuroendoscopy is considered a minimally invasive technique with good results, there is nevertheless a risk of developing certain complications. As no agreement apparently exists concerning the classification of these complications, we aim to propose a form of classification based on the results of our series, comparing them with recent publications. We undertook a retrospective study of 170 children who underwent intraventricular neuroendoscopy between 2003 and September 2020 at our center.

Neuroplasticity and Epilepsy Surgery in Brain Eloquent Areas: Case Report.

Neuronal plasticity includes changes in any component of the central nervous system in response to intrinsic or extrinsic stimuli. Brain functions that depend on the epileptogenic cortex pose a challenge in epilepsy surgery because many patients are excluded from pre-surgical evaluation for fear of the possible sequelae. Some of these patients may be rescued by enhancing neuronal plasticity with brain neuromodulation techniques.

Neuroendoscopic treatment of arachnoid cysts in the paediatric population. Series results for 20 patients.

Introduction: Neuroendoscopy has become an effective and safe treatment for arachnoid cysts in the paediatric population. We review the paediatric patients with arachnoid cysts treated by neuroendoscopy in our hospital and analyse the results.

Material And Methods: A retrospective analysis of 20 patients operated on from 2005 to 2018.

Preoperative evaluation by functional magnetic resonance imaging in patients with dysembryoplastic neuroepithelial tumours: A case series.

Introduction: Dysembryoplastic neuroepithelial tumours (DNET) are a type of benign glioneuronal neoplasia of typically temporal location that produce drug-resistant epileptic seizures in children and young adults.

Objective: This work aims to assess the usefulness of functional magnetic resonance imaging (fMRI) in the preoperative study in four patients with DNET. A Philips Intera 3.

Neuroendoscopic biopsy: analysis of a series of 80 patients.

Neuroendoscopy enables diagnostic biopsy of intraventricular and/or paraventricular tumors and the simultaneous treatment of associated hydrocephalus in selected cases. The objective of this paper was to analyze the effectiveness and safety of this procedure. This retrospective study included 80 patients between 2 months and 78 years old diagnosed with intraventricular and/or paraventricular expansive lesion who underwent neuroendoscopic biopsy from 2004 to 2016.

Purely neuroendoscopic resection of intraventricular tumors with an endoscopic ultrasonic aspirator.

Surgery for intraventricular tumors remains a controversial and evolving field, with endoscopic resection becoming more popular. We present a series of nine consecutive cases of purely endoscopic resection of intraventricular tumors with the aid of an ultrasonic aspirator specific for neuroendoscopy. Nine patients (five men, four women) aged 18-74 years (mean 43.

LOVA: the role of endoscopic third ventriculostomy and a new proposal for diagnostic criteria.

The diagnostic criteria and management of this condition continue to be a topic of debate in the literature. The term definitive symptomatic LOVA (longstanding overt ventriculomegaly in adults) is applied to patients that fulfil a series of diagnostic criteria,which are reviewed in our paper. The main subject of our study is to propose a rearrangement of the criteria for the diagnosis of this entity and adjusted treatment strategies.

Neuroendoscopic treatment for hydrocephalus associated to midline arachnoid cysts in a series of nine pediatric patients.

Background: Arachnoid cysts are extra-axial cerebrospinal fluid (CSF) collections surrounded by a membrane. Occasionally, hydrocephalus is associated due to a change in CSF circulatory dynamics. Neuroendoscopic treatment has been recommended for patients who develop symptoms resulting from the cyst location.

Endoscopic Third Ventriculostomy in Children with Myelomeningocele: A Case Series.

Hydrocephalus develops in up to 80-90% of children with myelomeningocele (MM) after closure of the defect. Traditionally, ventriculoperitoneal shunts have been used to manage hydrocephalus in these patients. A role for endoscopic third ventriculostomy (ETV) in MM has provoked much debate, principally due to anatomical variants described, which may complicate the procedure.

Endoscopic Third Ventriculostomy Success Score (ETVSS) predicting success in a series of 50 pediatric patients. Are the outcomes of our patients predictable?

Purpose: In our series of endoscopic third ventriculostomy (ETV), we sought to establish the relationship between the preoperative prediction using the Endoscopic Third Ventriculostomy Success Score (ETVSS) and the postsurgical success rate.

Materials And Methods: This descriptive analytical study comprised 50 pediatric patients who underwent 58 ETV procedures between 2003 and 2011. Data regarding clinical, surgical, and radiological findings were obtained from a continuously updated database.
