Device entrapment during percutaneous transluminal angioplasty for central venous stenosis in an arteriovenous fistula: a case report.
Article in Frontiers in medicine, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Not yet cited in PubMed.
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
Percutaneous transluminal angioplasty (PTA) is a widely used endovascular intervention for arteriovenous fistula (AVF)-associated stenosis. Balloon entrapment is an uncommon but clinically significant complication of endovascular procedures, which may lead to severe adverse events. We report a case of a patient who underwent bare-metal stent implantation for subclavian vein stenosis in 2025 and was re-admitted with limb swelling. Venography confirmed in-stent restenosis of the subclavian vein. During PTA for the target stenotic lesion, structural deformation of the balloon catheter occurred, leading to its entrapment. Multiple attempts at balloon deflation were unsuccessful. Successful retrieval of the damaged balloon catheter was accomplished via percutaneous subclavian vein puncture and percutaneous balloon puncture and decompression.
