Two Variants in One: Celiomesenteric Trunk with a Proximal SMA-originated Trunk with a Retrograde Hepatic Artery.
Article in Journal of cardiothoracic 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
purposeThis case report describes an asymptomatic 23-year-old male volunteer in whom an incidental celiomesenteric trunk (CMT) with an associated aberrant retrograde hepatic artery arising from the proximal superior mesenteric artery (SMA) was identified during an educational ultrasound session.
methodsHigh-resolution ultrasonography with color Doppler was used to visualise the abdominal aorta and its visceral branches in both sagittal and transverse planes.
resultsImaging demonstrated a single common trunk originating from the anterior abdominal aorta, which bifurcated into the celiac trunk and SMA. Additionally, a distinct arterial branch arose from the proximal SMA and coursed superiorly toward the porta hepatis, consistent with a replaced right hepatic artery following a retrograde trajectory.
conclusionThis combination of a CMT and a retrograde replaced right hepatic artery from the proximal SMA represents an uncommon anatomical configuration with direct implications for complex aortic debranching procedures, mesenteric revascularisation, and hepatopancreatobiliary surgery. The case also illustrates the educational value of point-of-care ultrasound in revealing anatomical variations beyond the classic textbook description.
