Usefulness and safety of trans-radial endovascular therapy for puncture-site bleeding in a patient with acute coronary syndrome requiring mechanical circulatory support.

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
A 66-year-old man with acute coronary syndrome underwent emergency percutaneous coronary intervention (PCI) using Impella CP (Abiomed, Danvers, MA, USA) via the left common femoral artery (CFA). After PCI, he experienced shock and severe anemia. A computed tomography scan revealed a large retroperitoneal hematoma caused by femoral puncture-site bleeding. He was in hemorrhage and cardiogenic shock, so we needed to achieve hemostasis without removing Impella CP. We performed endovascular therapy (EVT) through the radial artery system. Angiography showed ongoing bleeding in the left CFA. Initially, we attempted balloon tamponade with an 8-mm semi-compliant balloon, but this was unsuccessful. We then performed percutaneous thrombin injections combined with balloon tamponade. Ultimately, we achieved hemostasis at the puncture site. Our case suggests that trans-radial EVT combined with percutaneous thrombin injection is a useful and safe method for controlling femoral puncture-site bleeding. Learning objective: Trans-radial endovascular therapy combined with percutaneous thrombin injection is a useful and safe method for controlling femoral puncture-site bleeding, even in patients requiring mechanical circulatory support.
