Quadrigeminal cistern Arachnoid cyst, endoscopic approach

This video showcases the endoscopic approach for combined ETV (endoscopic third ventriculostomy) for treatment of hydrocephalus resulting from a quadrigeminal cistern arachnoid cyst compressing the CSF pathway along with endoscopic fenestration of the cyst through cysto-ventriculostomy. Type III arachnoid cyst according to the classification by Cinalli and colleagues show lateral supratentorial extension towards the temporal lobe. Achieving a cysto-cisternostomy via a transventricular route ensures continued drainage of the arachnoid cyst into 2 routes; the ventricular and subarachnoid compartment but this is not readily achievable in all cases. In any event, wide fenestration and cauterization of the leaflets of the openings made in the cyst wall ensures adequate and durable drainage after decompression and when the walls collapse by minimizing the re-closure potential of such fenestrations.
