Contrast-Enhanced Magnetic Resonance Imaging Suggested a Possibility of Transvenous Embolization in the Superior Petrosal Sinus Dural Arteriovenous Fistula: A Case Report.

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
Objective: Superior petrosal sinus dural arteriovenous fistula (SPS-DAVF) is a rare subtype of intracranial DAVF that sometimes leads to hemorrhagic symptoms following deep venous drainage. Here we report the case of SPS-DAVF with retrograde venous reflux to the cerebellar vein. Preoperative contrast-enhanced MRI was a decisive factor in a safe and effective treatment. Case Presentation: A 37-year-old woman was referred to our hospital with abnormal MRI findings, which was performed when she had a mild headache during her check-up. DSA revealed left-sided SPS-DAVF, which was diagnosed as Cognard type IIb. Both CTA and DSA could not detect the whole SPS but only the shunt pouch. Using contrast-enhanced MRI, we were able to visualize the presence of the SPS and its continuity within the shunt pouch. 3D-T1 turbo spin echo (SPACE) showed a low-intensity area in the SPS, which was not seen in the 3D-T1 fast field echo (FFE). During the procedure, there was a point where it was difficult to advance the microcatheter, which coincided with the low-intensity area. We achieved effective transvenous embolization from the occluded venous access by devising a surgical technique. Conclusion: In addition to the contrast-enhanced 3D-T1 FFE, 3D-T1 SPACE might provide beneficial information for endovascular therapy in the evaluation of venous sinuses, which could not be detected by standard examinations.
