Rectal Arteriovenous Malformation Mimicking a Submucosal Tumor: Successful Long-Term Outcome After Transcatheter Arterial Embolization With N-Butyl-2-Cyanoacrylate-Lipiodol.
Article in DEN open, 2026. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 1 paper.
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
Rectal arteriovenous malformations (AVMs) are rare vascular anomalies that pose diagnostic challenges because they may resemble submucosal tumor-like lesions. A 54-year-old man presented with recurrent hematochezia, and a colonoscopy revealed a protruding lesion near the dentate line. Contrast-enhanced computed tomography and angiography confirmed a rectal AVM classified as Cho type IIIb/Yakes type II. Transcatheter arterial embolization with N-butyl-2-cyanoacrylate-Lipiodol (NL) was performed. A rectal ulcer that developed 2 weeks after treatment was successfully managed with topical hydrocortisone. Follow-up colonoscopy demonstrated progressive lesion regression without recurrence at 3 years. This case underscores that rectal AVMs may mimic submucosal tumors and require a multimodal diagnostic approach. Transcatheter arterial embolization with NL represents an effective therapeutic option.
