Multiple systemic embolization after endoscopic cyanoacrylate injection for gastric variceal bleeding: a case report.
Article in Journal of medical case reports, 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
backgroundEndoscopic cyanoacrylate injection (ECI) is an established first-line treatment for gastric variceal bleeding (GVB). However, a rare but potentially fatal complication of this therapy is systemic embolization of the cyanoacrylate, most often to the lungs or spleen, while emboli to systemic circulation are exceedingly uncommon. CASE PRESENTATION: We report the case of a 71-year-old Asian male patient with cirrhosis who was found to have gastric variceal bleeding. He underwent endoscopic variceal obliteration using histoacryl (N-butyl cyanoacrylate) injection under intravenous anesthesia. Postprocedure, he exhibited delayed emergence from anesthesia and remained comatose. Laboratory and imaging examinations led to the diagnosis of multiple systemic embolization involving the brain, heart, spleen, and spinal cord, caused by cyanoacrylate.
conclusionAlthough multiple systemic embolization is extremely rare, clinicians should be vigilant for this complication, especially in patients with abnormal shunts. Careful preprocedural screening for shunts, meticulous injection technique, and close monitoring may facilitate early detection and timely intervention, potentially improving patient outcomes.
