Morphological characteristics and outcomes of aortic repair of acute type A aortic dissection occurring in patients with aortic arch branching variants.
Article in Surgery today, 2025. The graph could read no effect estimate from its abstract, so it casts no vote on the map. Cited by 3 papers.
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
purposeTo investigate the morphological characteristics and operative outcomes of acute type A aortic dissection (ATAAD) in patients with aortic arch variants.
methodsOf 616 patients with ATAAD, 97 (15.7%) had aortic arch variants, including bovine aortic arch (BAA, n = 66), isolated left vertebral artery (ILVA, n = 25), and aberrant subclavian artery (ASA, n = 6). The characteristics and outcomes were compared between the normal branching group (control, n = 519) and the total/individual arch variant groups.
resultsCompared to the control group, arch entry was more prevalent in the BAA (18.5% vs. 31.8%) and ILVA groups (44%) (both, P < 0.05), and right common carotid arterial occlusion was less common in the arch variant group (6.7% vs. 0%, P = 0.017). The in-hospital mortality (9.2% vs. 9.3%), new-onset stroke (7.3% vs. 7.2%), and 5-year survival (81.7% vs. 78.8%) did not differ markedly between the control and arch variant groups. Arch repair was performed in 28.9% (28/97) of the arch variant group using 3-4 vessel antegrade cerebral perfusion, with 3.8% in-hospital mortality and a 15.4% stroke rate, which were comparable to those of the control group.
conclusionsAortic arch variants may influence tear location and involvement of the supra-arch vessels but may not affect postoperative outcomes.
