Splenic artery fenestration - a previously undescribed arterial variant.
Article in Surgical and radiologic anatomy : SRA, 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
purposeThe splenic artery exhibits considerable morphological variability; however, true arterial fenestrations are exceedingly rare within the abdominal vasculature. We report a previously undocumented splenic artery fenestration identified on computed tomography angiography (CTA) in a 70-year-old male. ANATOMIC VARIATION: The artery followed an intrapancreatic course and demonstrated a true fenestration located 33.1 mm from its origin. The fenestrated segment consisted of a superior limb measuring 6.1 mm in diameter and an inferior limb measuring 6.1 mm, with distal reconstitution into a single lumen over a length of 15.4 mm. The finding was consistently visualized using multiplanar reconstructions and three-dimensional volume-rendered CTA images, without evidence of mural irregularity, intimal flap, or arterial dissection.
conclusionsRecognition of this rare arterial configuration is important for radiologists, surgeons, and interventionalists, as it may mimic arterial duplication or dissection and has potential implications for endovascular and surgical procedures involving the splenic artery.
