Abstract: Neuroendoscope has unique advantages in observing the relationship between intracranial aneurysms and peripheral vessels and nerves during intracranial aneurysm clipping. With the development of neuroendoscope technology, as well as the assistance of endoscopic light and display system, the clipping effects of some intracranial aneurysms have significantly improved. Although there are still the lack of depth of the operation field, the space occupying of the endoscope itself and iatrogenic injury, with the development of endoscopic equipment and operation methods, neuroendoscope will play its role in the surgical treatment of intracranial aneurysms.
