Giant splenic artery pseudoaneurysm fistulizing to the colon: A case report and focused literature review.
Article in Radiology 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
Splenic artery pseudoaneurysm (SAP) is a rare but dangerous visceral arterial lesion, and fistulization into the gastrointestinal tract is an exceptional and life-threatening complication. We report the case of a 73-year-old woman presenting with acute lower gastrointestinal bleeding caused by a giant SAP that had eroded into the splenic flexure of the colon. Proximal embolization using coils and Onyx achieved initial hemostasis. Although the patient was clinically stabilized, she later developed delayed septic and inflammatory complications requiring splenectomy, colonic resection, partial gastrectomy, and removal of the aneurysmal sac. This case, together with our focused review of published SAP fistula cases, highlights that embolization should be considered a temporizing measure when gastrointestinal fistulization is present; early surgical management remains essential to prevent severe infection and multi-organ complications.
