Safety and diagnostic accuracy of neuroendoscopic biopsies: an international multicenter study.

Object: Analysis of the safety and morbidity of neuroendoscopic biopsies (NEBs), as well as the reliability in obtaining an accurate diagnosis, has until now been based on studies with relatively small sample sizes. Through the cooperative efforts of several international medical centers, authors of the present study collected data on a large number of patients to obtain better insight into this issue. When possible, they compared pathology obtained through an NEB with the "gold-standard" pathology obtained in open surgery.

Neurotoxic effect of povidone-iodine on the rat spine using a laminectomy-durotomy model.

Objective: The efficacy and safety of povidone-iodine in wound dressing and irrigation of some operative cavities were established by many in vitro and in vivo experimental reports and clinical series. However, its use in defective tissue in neural structures has not been confirmed yet. The aim of the present study was to histopathologically investigate its effect on neural tissues when applied on the upper side of defective dura.

Neuroendoscopic surgery in empty ventricular system under continuous gas infusion experimental study of pressure changes and complications.

Introduction: The most important limitations to endoscopic procedures in the ventricular system of the brain are due to the constraint of working inside a fluid. The evacuation of cerebrospinal fluid (CSF) from the ventricles is performed often in microsurgical interventions using a surgical microscope. This study aimed at studying the evacuation of CSF during neuroendoscopic surgery in animals while infusing gas to avoid ventricular collapse.

Fenestration methods for Sylvian arachnoid cysts--endoscopy or microsurgery.

Introduction: Two different approaches to fenestration, endoscopic and microsurgical, are in use for Sylvian arachnoid cysts (SACs), the most frequent among intracranial arachnoid cysts. We presented the clinical data and compared our results, with regard to technique and clinical success, with either microsurgical or neuroendoscopic fenestration of SACs.

Materials And Methods: Twenty-nine patients who subjected to cysto-cisternostomy by the same team, using either of the two methods, were studied retrospectively.

Indirect bypass procedures for moyamoya disease in pediatric patients.

In this study, indirect surgical intervention methods especially used in combination with pial synangiosis were assessed together with other indirect methods.

Cerebro-spinal fluid shunt revisions, importance of the symptoms and shunt structure.

Aim: CSF shunt failure is still a frequent problem in children. This prospective study was designed for focusing symptoms and reasons of shunt failure. We also especially focused on the mechanical reasons of shunt failure.

Intraventricular migration of the bone dust. Is a second operation for removal necessary? Case report and review of the literature.

Purpose: As the number of endoscopic third ventriculostomy (E3V) operations increase, new rare complications are encountered. In this article, a complication caused by bone particles that migrated into the third ventricle will be described. Additionally, the methods of avoidance as well as the necessity of a new approach will be discussed.

Near-infrared camera for intraventricular neuroendoscopic procedures: in vitro comparison of the efficiency of near-infrared camera and visual light camera during bleeding.

Purpose: Bleeding is the most important problem in neuroendoscopic procedures. The visibility of the bleeding point for a long period of time is very crucial for the surgeon to stop the bleeding. In this study, the performances of a near-infrared camera (NIRC) and a visible light camera (VLC), which is widely used today, were compared in terms of the visibility duration of the bleeding point.

Can using a peel-away sheath in shunt implantation prevent ventricular catheter obstruction?

Purpose: Shunt obstruction is the most common shunt complication. In 2003, Kehler et al. used peel-away sheath while implanting the ventricular catheter in 20 patients.

Establishment of interdisciplinary child protection teams in Turkey 2002-2006: identifying the strongest link can make a difference!
