Abstract
Objective: This article demonstrates the feasibility of using a videoscope system with narrow-band imaging (NBI) technology to enhance the safety of endoscopic third ventriculostomy (ETV). Methods: ETV was performed on two longstanding overt ventriculomegaly in adults (LOVA) patients using a videoscope system with narrow-band imaging technology. All procedures were digitally recorded. Images obtained from this new videoscope were compared with images from a conventional fiberscopy performed earlier. To determine the usefulness of the NBI technology, the digital photographs were organized so as to compare the conventional and NBI images. Results: The visual quality of the videoscope was far superior to the conventional fiberscope. Clear visualization of 1) the subependymal blood vessels, 2) tiny capillaries in the ventricular floor, and 3) perforators of the basilar artery on the other side of the floor, was obtained. Furthermore, when used in conjunction with narrow-band imaging technology, the videoscope was capable of producing enhanced images of the blood vessels aforementioned. Conclusion: This videoscope is effective in avoiding vessel injuries, and thus hemorrhage, during ETV. Though yet to be assessed, its usefulness in other neuroendoscopy procedures seems promising. Videoscopy with NBI technology is expected to be a new paradigm in the development of neuroendoscop.
