Blood management with preoperative autologous blood in valve-sparing root replacement: separated autologous red blood cells and plasma and fibrin sealant versus autologous whole blood.
Article in General thoracic and cardiovascular surgery, 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
objectivesWe investigated the effects of the combined use of preoperatively separated autologous red blood cells, plasma, and fibrin sealant on reducing allogeneic blood transfusion during valve-sparing root replacement using the aortic root remodeling technique, by comparison with transfusion of refrigerated, predeposited autologous whole blood.
methodsThirty-nine patients underwent elective, initial valve-sparing root replacement using the aortic root remodeling technique by a single surgeon between April 2018 and December 2023. Of these, 9 patients in Group A predeposited autologous whole blood until September 2019 and 12 patients in Group B predeposited separated autologous red blood cells, plasma, and fibrin sealant after October 2019. The intraoperative allogeneic blood transfusion avoidance rate was compared between Groups A and B.
resultsThe allogeneic blood transfusion avoidance rate in Group A was 66.7% for red blood cells, 55.6% for plasma, 55.6% for platelets, and 55.6% for all components combined. In Group B, the avoidance rate was 100% for each component, significantly higher than in Group A for plasma, platelets, and all components combined (all P = 0.021). Postoperative hemoglobin level was significantly higher and amount of chest tube drainage during the first 12 postoperative hours was lower in Group B.
conclusionsThis before-and-after study suggested that the combined use of preoperatively separated autologous red blood cells and plasma and fibrin sealant can be an effective blood management strategy in patients undergoing valve-sparing root replacement using the aortic root remodeling technique, reducing intraoperative allogeneic blood transfusion compared with predeposited autologous whole blood transfusion.
