Valve-sparing root replacement with short saphenous vein interposition for left coronary artery reconstruction in redo type A aortic dissection: a case report.
Article in Journal of surgical case reports, 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
Redo aortic root surgery for acute type A aortic dissection is technically demanding, particularly when coronary reconstruction is complicated by tissue fragility. Reliable bailout strategies are required when direct coronary reimplantation is unsafe during valve-sparing root replacement. A 52-year-old man previously underwent total arch replacement with a frozen elephant trunk for acute type A aortic dissection. He later developed progressive aortic root dilatation and a proximal anastomotic pseudoaneurysm, and redo valve-sparing root replacement was performed. Intraoperatively, the left coronary artery was severely dissected and unsuitable for reimplantation. A short segment saphenous vein graft was interposed between the trimmed left main trunk and the neo-aortic root. Postoperative imaging confirmed preserved valve function and satisfactory coronary flow. Short-segment saphenous vein interposition represents a practical bailout option in complex redo aortic root surgery.
