Case Report: A rare case of giant ascending aortic dissecting aneurysm requiring redo sternotomy for rescue.

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
Background: Here, we report a rare case of a 45-year-old female with a giant ascending aortic dissecting aneurysm (diameter >10 cm) who underwent a redo sternotomy for rescue. Methods: The patient had aortic coarctation repair and mechanical aortic valve replacement 20 years earlier. Although the patient had significant surgical risks due to a low hemoglobin level and long-term warfarin use, urgent surgical intervention was deemed necessary. The surgery involved cannulating the femoral artery and vein, splitting the sternum, and carefully dissecting the aneurysm. A 23-mm valve conduit was implanted, and the left coronary ostium was transplanted. The right coronary ostium was anastomosed using the Cabrol technique. Results: The surgery was successful, with a total operative time of 4 h and 25 min, cardiopulmonary bypass time of 143 min, and aortic cross-clamp time of 78 min. Postoperatively, the patient experienced frequent episodes of cardiac arrest, which resolved with the implantation of a temporary pacing device. Postoperative imaging showed satisfactory results, and the patient was discharged on the ninth postoperative day. Conclusion: This case reports the successful management of a complex and high-risk surgical scenario and provides valuable insight for similar cases.
