Using the snare system to cross the acute-angled vertebrobasilar junction in treating posterior inferior cerebellar artery aneurysm with the stent-assisted method via a retrograde approach. A technical note.

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
Retrograde stenting via the contralateral vertebral artery (VA) is a safe and effective treatment for posterior inferior cerebellar artery (PICA) aneurysm. Many methods, including tip shaping and the looping technique, have been attempted as ways to cross the vertebrobasilar (VB) junction. Here, we introduce an alternative method using a Snare system to overcome the acute-angled VB junction after repeated failures using other techniques. The Snare system was navigated to the proximal basilar artery via the ipsilateral VA. A guidewire was introduced in the contralateral VA and gently advanced to the basilar artery in order to pass through the loop of the Snare system. Following this, the Snare system caught the guidewire and it was very carefully pulled down to the ipsilateral VA crossing the VB junction. We suggest this technique as a method to cross the acute-angled VB junction after failure of all other attempts to overcome this challenge.
