Type V tentorial dural arteriovenous fistula: a case of augmented reality-assisted surgical salvage.
Article in Neurosurgical focus: Video, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
What it found
Each row is one number read from the abstract, on the scale the paper reported it, with its interval. Left of the dashed line favours the treatment, right favours the comparator. Under each row is the sentence it came from. New to these charts? A ten-minute tutorial.
The abstract states no effect estimate the extractor could read, or names no intervention and outcome on the map, so this paper lights no cell and moves no belief. It is still indexed, cited and linked below.
The trial behind it
Trials whose registry record cites this paper, or whose number appears in the abstract. A trial that started after this paper was published is citing it as background, not reporting it.
Neither the registry nor the abstract names a trial number. If this is a trial report, that itself is worth knowing.

Abstract
This video demonstrates the case of a Cognard type V tentorial dural arteriovenous fistula that was successfully salvaged using augmented reality-assisted microsurgery following failed endovascular embolization. The patient had a spastic gait and quadrilateral numbness. MRI showed medullary edema and abnormal vessels near the tentorium. DSA confirmed a shunt fed by the meningohypophyseal trunk draining into perimedullary veins. Initial embolization was unsuccessful. Using CISS MRI and augmented reality projection, the authors identified and ligated the arterialized veins, relieving venous hypertension. Postoperative imaging showed improvement of the brainstem edema. The video can be found here: https://stream.cadmore.media/r10.3171/2025.7.FOCVID2541.
