Transcranial Transvenous Embolization with Onyx through a Steerable Catheter for a Dural Arteriovenous Fistula of the Isolated Superior Sagittal Sinus: A Technical Case Report.
Article in NMC case report journal, 2026. 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
We report a rare case of an isolated superior sagittal sinus dural arteriovenous fistula successfully treated by transcranial direct puncture transvenous Onyx embolization using a steerable microcatheter. With reduced arterial inflow and sinus balloon protection, Onyx injection through the steerable catheter achieved complete occlusion of the shunted pouch without complications. The patient showed marked improvement in cortical venous dilatation and cerebral edema. This case highlights the feasibility and safety of combining transarterial flow reduction, sinus balloon protection, and steerable microcatheter navigation for the curative embolization of isolated sinus dural arteriovenous fistulas.
