A case of abnormally dilated and tortuous arc of Buhler and pancreaticoduodenal arteries in the absence of celiac trunk stenosis.

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
introductionThe Arc of Buhler is a rare vascular variant describing a persistent remnant of the embryologic ventral anastomosis between the celiac trunk (CT) and superior mesenteric artery (SMA), invariably reported in the context of CT stenosis. PURPOSE: To report a case of (1) a large and tortuous pancreaticoduodenal arcade and (2) a large and tortuous Arc of Buhler in the absence of celiac axis stenosis.
methodsThe variant was discovered during routine cadaver dissection. We acquired transverse biopsies of variant vessels and evaluated their wall thickness.
resultsThe donor's anterior PDA, posterior PDA, and Arc of Buhler had larger diameters, and the common hepatic artery had a smaller diameter than the literature-reported values of a standard human body. The posterior PDA had significantly increased wall thickness compared to the other investigated vessels.
conclusionsThe Arc of Buhler is a rare remnant of the embryologic ventral anastomosis that is estimated to be hemodynamically active in only half of cases. Previous reports have documented hemodynamically active Arcs of Buhler only in cases of CT stenosis. To the best of the authors' knowledge, this is a unique case of a persistent and hemodynamically active Arc of Buhler in the absence of CT stenosis. Clinicians should be aware of this variant as its abnormal position may increase risk of herniation and surgical complications, and its tortuosity may increase risk of clot formation.
