Treatment of direct carotid-cavernous fistula with Willis covered stent with midterm follow-up.
Article in Chinese neurosurgical journal, 2021. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 4 papers.
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
backgroundWillis covered stent is the first stent designed exclusively for intracranial vasculature, and its application in carotid-cavernous fistula is limited. The aim is to evaluate the feasibility and efficacy of this device in treating direct carotid-cavernous fistula.
methodsTen consecutive patients with direct carotid-cavernous fistula were treated in our institution with Willis covered stents from September 2013 to December 2015. The characteristics of these patients and the immediate and follow-up results were retrospectively reviewed.
resultsOf the 10 patients, 8 were treated for the first time, and 2 had been treated elsewhere. Willis covered stents were successfully released in 9 patients. Abnormal arteriovenous shunt disappeared in 6 cases immediately after stent deployment and endoleak occurred in 3 cases. Endoleak disappeared at 6-month angiography follow-up in one case and was sealed with coils through a pre-set microcatheter in another case. Parent artery was sacrificed as endoleak remained despite repeated balloon dilation and a second stent deployment in the third case. All patients got clinical follow-ups for at least 24 months and 7 patients received angiographic follow-up. Symptoms were relieved gradually in all cases except for slight oculomotor paralysis and visual acuity in one case, respectively. In-stent stenosis was found in 1 case, and no recurrence was observed.
conclusionsWillis covered stent is feasible for direct carotid-cavernous fistula.
