Open Repair of a True Aneurysm of the Superior Mesenteric Artery.
Article in JACC. Case reports, 2025. 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
backgroundCurrent international guidelines indicate endovascular approach as the gold standard for treatment of superior mesenteric artery aneurysms (SMAAs). However, some cases require open surgery because of anatomical or pathologic constraints. CASE SUMMARY: We report 2 cases of SMAAs treated with open repair at our institution: a 46-year-old man with suspected Ehlers-Danlos syndrome and a thrombosed SMAA who underwent an aortomesenteric bypass using a saphenous vein graft and a 65-year-old man with a dissecting SMAA and rapid aneurysm growth who received an interposition graft with the superficial femoral artery. Both had uneventful recoveries. DISCUSSION: Despite the advantages of endovascular repair, open surgery is crucial for cases with infection, collagenous diseases, or complex anatomy. A tailored approach optimizes outcomes. TAKE-HOME MESSAGES: Open surgery remains necessary for complex SMAAs. Alternative arterial grafts, such as the superficial femoral artery, can be valuable substitutes.
