Aortic pseudoaneurysm in a patient with systemic lupus erythematosus following Bentall procedure and coronary artery bypass grafting: a case report.
Article in Journal of cardiothoracic 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
backgroundAortic pseudoaneurysm is among the most severe and life-threatening complications following cardiac surgery. Although technical failure or infection is commonly identified as the primary cause, underlying connective tissue disorders, such as systemic lupus erythematosus, may significantly increase susceptibility to pseudoaneurysm formation due to inherent tissue fragility. CASE PRESENTATION: We report a case of a 49-year-old female patient with preoperative systemic lupus erythematosus who underwent a concomitant Bentall and coronary artery bypass grafting procedure. Four months postoperatively, she presented with hemorrhagic drainage from the upper sternal incision. Computed tomography angiography revealed a mediastinal mass and a large aortic pseudoaneurysm. Intraoperative assessment revealed dehiscence at the anastomotic sites of both the left main coronary artery button and the saphenous vein graft to the right coronary artery, where they were attached to the Bentall graft.The pseudoaneurysm was completely excised, and the left main coronary artery was reconstructed using a prosthetic graft. The patient was discharged after reoperation.
conclusionThis case emphasizes the importance of considering systemic autoimmune diseases, particularly systemic lupus erythematosus, as a contributing factor to vascular complications following aortic root replacement. Systemic lupus erythematosus-related connective tissue fragility may impair graft healing and anastomotic integrity, even in the absence of infection. Prompt diagnosis and timely surgical intervention are essential to mitigate the risk of mortality and improve clinical outcomes.
