Malposition of the Selective Antegrade Cerebral Perfusion Catheter Identified by Carotid Ultrasonography: A Case Report.
Article in Annals of cardiac anaesthesia, 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
abstractCerebral hypoperfusion can occur during aortic surgery. We present a case in which malposition of the selective antegrade cerebral perfusion (SACP) catheter was identified using carotid ultrasonography. A 66-year-old man underwent total arch replacement. SACP was initiated via the brachiocephalic artery following deep hypothermic circulatory arrest. However, right forehead regional oxygen saturation (rSO2) remained unchanged. Carotid ultrasonography revealed no blood flow in the right common carotid artery, suggesting catheter malposition into the right subclavian artery. After a slight catheter withdrawal, blood flow was restored, and rSO2 increased. Carotid ultrasonography, along with rSO2 monitoring, is recommended for evaluating cerebral perfusion during SACP.
