Cavernous Sinus Dural Arteriovenous Fistula: Treatment via the Transfemoral Transfacial Route.
Article in AJNR. American journal of neuroradiology, 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
Cavernous sinus dural arteriovenous fistulas (dAVFs) are most frequently treated by a transvenous approach via the inferior petrosal sinus (IPS). However, in certain patients, the IPS is not amenable to navigation. In this technical video, we present the case of a patient with a cavernous sinus dAVF embolized by the transfemoral transfacial venous route on a failed attempt to catheterize the IPS. Preprocedural head and neck imaging was performed, documenting the facial vein draining to the internal jugular vein via the common facial vein on the side of the fistula. Embolization was accomplished without complications, with complete exclusion of the fistula. We suggest that treatment via the transfemoral transfacial venous pathway should be attempted and followed through whenever the IPS is not amenable to catheterization, on the basis of favorable preprocedural anatomy and the safety and efficacy demonstrated in several published case series.
