Successful Treatment of a Ruptured Left Internal Carotid Artery Aneurysm with a Type III Aortic Arch Using an α-shaped Guiding Catheter: A Technical Case Report.
Article in NMC case report journal, 2024. 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
In endovascular therapy, the induction and stable placement of the guiding catheter (GC) are not only the initial steps but also crucial techniques influencing treatment success. However, in some cases, GC induction is challenging due to variations in the aortic arch or tortuosity of the blood vessels. In the present case, endovascular therapy was carried out for a ruptured aneurysm in the dorsal portion of the left internal carotid artery. However, conventional GC could not be induced because of the type III aortic arch and extremely steep angle. By switching to an α-shaped GC, employed in conjunction with a distal access catheter, we were able to reach the aneurysm with a microcatheter and successfully complete the treatment. The tip of the α-shaped GC was positioned in the ascending aorta and thus required various considerations in terms of setup and device selection when compared to conventional techniques. This is the first report of the use of this catheter for the acute treatment of ruptured cerebral aneurysms. In this report, we share our experience and the effectiveness of using this catheter while highlighting our considerations.
