Predictive factors for post-embolization infarction and long-term splenic remodeling in patients undergoing splenic artery aneurysm embolization.
Article in Frontiers in surgery, 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
Objective: To identify predictive factors for post-embolization splenic infarction and to assess long-term remodeling patterns of the spleen, including regeneration and atrophy, in patients undergoing embolization for splenic artery aneurysm (SAA). Methods: This retrospective study included 64 patients (66 cases) with splenic artery aneurysms who underwent transcatheter arterial embolization between February 2007 and November 2023 at a single tertiary center. Embolization techniques included sac packing, trapping, combined approaches, and stent-graft placement. Results: Technical success was achieved in all 66 cases. Clinical success was obtained in 94.1% of evaluable patients, with two cases of recanalization and one new aneurysm detected during follow-up. Splenic infarction occurred in 24 patients (37.5%) and was associated with distal or hilar/intrasplenic location ( Conclusion: Endovascular embolization for splenic artery aneurysms was safe and effective. Post-embolization splenic staining on angiography was the key predictor of infarction and was also associated with long-term splenic regeneration.
