Intraventricular neuroendoscopy: Complication avoidance and management

In the modern era, neuroendoscopy has had an increasingly prominent role in neurosurgery. As attention has focused the development of minimally invasive surgical methods, neuroendoscopy has advanced both as an independent treatment modality for various neurologic disorders and as an adjunct to microneurosurgery. Neuroendoscopy is distinct from traditional surgery, and a thorough understanding of its unique attributes is required to attain maximal benefit. In addition to its advantages, neuroendoscopy is associated with unique obstacles that must be anticipated, appreciated, and accounted for to prevent complications. This article outlines techniques to reduce and manage complications during more common intraventricular neuroendoscopic procedures including endoscopic third ventriculostomy (ETV), colloid cyst resection, tumor biopsy and resection, and treatment of loculated hydrocephalus.
