Abstract

Novel adaptation of the AxiEM electromagnetic neuronavigation system for intraoperative tracking of neuroendoscope during intraventricular surgery

Highlights

Endoscopic third ventriculostomy is a minimally invasive neurosurgical procedure which is the most commonly used to treat hydrocephalus via creating an opening in the floor of the third ventricle which allows excess cerebrospinal fluid to flow into surrounding basal cisterns by bypassing obstructions
Endoscopic third ventriculostomy and neuroendoscopic intraventricular surgery overcome the persistent risk of infection and hardware failure associated with ventriculoperitoneal shunting for the treatment of hydrocephalus
A retrospective chart review of adult and pediatric patients treated with neuronavigation-guided endoscopic third ventriculostomy (ETV) or intraventricular cyst fenestration for radiographically confirmed and clinically significant congenital or acquired hydrocephalus in university hospital setting between 2012–2014; n = 21 patients was performed

Summary

Introduction

Endoscopic third ventriculostomy is a minimally invasive neurosurgical procedure which is the most commonly used to treat hydrocephalus via creating an opening in the floor of the third ventricle which allows excess cerebrospinal fluid to flow into surrounding basal cisterns by bypassing obstructions. Endoscopic third ventriculostomy and neuroendoscopic intraventricular surgery overcome the persistent risk of infection and hardware failure associated with ventriculoperitoneal shunting for the treatment of hydrocephalus. Case Series: The aim of this case series is to assess the safety and effectiveness in surgical outcomes of adding neuronavigation tracking to endoscopic visualization for intraventricular surgery. A retrospective chart review (case series) of adult and pediatric patients treated with neuronavigation-guided endoscopic third ventriculostomy (ETV) or intraventricular cyst fenestration for radiographically confirmed and clinically significant congenital or acquired hydrocephalus in university hospital setting between 2012–2014; n = 21 patients was performed. Adding image guidance to neuroendoscopy increases safety margins for targeting accuracy, especially for patients with challenging anatomic landmarks.
