Visualization of the anterior cerebral artery complex with a continuously variable-view rigid endoscope: new options in aneurysm surgery.

Background: Neuroendoscopy is increasingly used as an adjunctive tool in intracranial aneurysm surgery.

Objective: To assess the versatility of a prototype continuously variable-view rigid endoscope in visualizing the anterior cerebral artery complex.

Methods: In 5 formaldehyde-fixed, arterially injected specimens, a standard frontolateral approach was used on both sides.
