1 · What the graph read from it

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.

2 · The registry

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

introThere is a growing preference among neurointerventionalists for transradial access (TRA) over transfemoral access (TFA) due to improved patient satisfaction, recovery time and reduced access site complication, but using balloon guide catheters (BGCs) in the radial artery remains a challenge. We report our experience in successfully using the 0.087" inner diameter Walrus BGC without a sheath via the radial artery for non-emergent neurointerventions.

objectiveDescribe the technique for safely accessing the radial artery using the sheathless Walrus balloon guide catheter.

methodsA retrospective chart review of thirteen consecutive patients who underwent intervention with radial artery access with a sheathless Walrus BGC was performed.

resultsAll twelve procedures were performed successfully with no instances of conversion from TRA to TFA. There were no significant procedural or access site complications. The mean radial diameter was 2.51 mm.

conclusionsThe Walrus 0.087" ID BGC is an effective tool that can safely be used via the radial artery using a sheathless approach, which helps to maximize the size of the catheter that can be used. This is the first instance of our knowledge of this technique being utilized for neurointerventions and therefore could be used to expand the indications for TRA for a wider range of procedures.
