Acquired progressive torcular dural arteriovenous fistula after subtotal resection of peritorcular meningioma.

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
A woman in her mid-50s who had undergone a subtotal resection of a peritorcular meningioma 3 years earlier presented with symptoms suggestive of increased intracranial pressure. A delayed diagnosis of a torcular dural arteriovenous fistula (dAVF) diagnosis was made on MRI. Digital subtraction angiography confirmed a torcular dAVF (Borden type II). Staged 3 rounds of transarterial (TA) embolisation were performed using n-butyl cyanoacrylate, ethylene vinyl alcohol copolymer and coils of the complex torcular dAVF, which significantly reduced the flow and corresponded with improved symptoms of pulsatile tinnitus, vision and headache. We reviewed previously reported cases of dAVFs that developed after craniotomy for meningioma resection. Despite its rarity, a torcular dAVF can develop after craniotomy and progress from low to high grade due to its location. Diagnosis requires a thorough understanding of subtle imaging findings, which may be present in follow-up studies obtained for tumour surveillance.
