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.

Re-Do endoscopic third ventriculostomy. Retrospective analysis of 13 patients.

Objetives: Indication for endoscopic third ventriculostomy (ETV) in the treatment for noncommunicating hydrocephalus is widely accepted. There is controversy regarding the indication of a second procedure (re-ETV) when the first has failed. The objective of this work is to revise ETV failures in a series in which re-ETV was performed and to describe the factors related to its prognosis.

Quality of life in children with hydrocephalus treated with endoscopic third ventriculostomy.

Objective: The objectives of this study were to determine the quality of life of a pediatric cohort with hydrocephalus treated by endoscopic third ventriculostomy (ETV), using the Hydrocephalus Outcome Questionnaire-Spanish version (HOQ-Sv), and study the clinical and radiological factors associated with a better or worse functional status.

Methods: This cross-sectional study was undertaken between September 2018 and December 2019. It comprised a series of 40 patients ranging from 5 to 18 years old with hydrocephalus treated by ETV.

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.

LINAC radiosurgery treatment for vestibular schwannoma.

Objective: The aims of our study were to evaluate tumour response in a series of patients with vestibular schwannoma (VS) treated with linear accelerator stereotactic radiosurgery (LINAC-RS), to describe the complications and to analyze the variables associated with the response to treatment.

Material And Methods: This retrospective descriptive study included 64 patients treated from 2010 to 2016 with a minimum follow-up of one year, excluding patients with neurofibromatosis. Clinical-radiological parameters were evaluated.

Atypical Meningiomas: Histologic and Clinical Factors Associated With Recurrence.

Background: Atypical meningioma is a heterogeneous group of tumors with an unpredictable behavior. Our objectives were to study patients with atypical meningioma, monitor their follow-up, identify the histologic characteristics, and analyze factors associated with severe outcomes.

Methods: This retrospective study involved 28 patients with atypical meningioma from 1994 to 2014.

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.
