Intrapleural left axillary artery bypass grafting compromising subsequent left internal thoracic artery harvesting: 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
The frozen elephant trunk technique is increasingly used in total arch replacement (TAR) for acute Type A aortic dissection, with left axillary artery bypass commonly employed for left subclavian artery revascularization. We report a case in which an intrapleural left axillary artery Dacron bypass graft led to dense perigraft adhesions that severely compromised subsequent left internal thoracic artery (LITA) harvesting during redo coronary artery bypass grafting. A 45-year-old man underwent valve-sparing aortic root reimplantation, TAR, and left axillary artery bypass. Intraoperative findings revealed dissection extending to the left main trunk ostium, necessitating an arch prosthesis-to-left anterior descending saphenous vein graft, which subsequently failed. Dense intrapleural adhesions surrounding the graft severely impaired LITA harvesting. Complete arterial revascularization was achieved using bilateral internal thoracic arteries and radial artery bridge conduits. This case highlights that intrapleural routing of a left axillary artery bypass graft may compromise future LITA harvesting.
