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 hours and 25 minutes, cardiopulmonary bypass time of 143 minutes, and aortic cross-clamp time of 78 minutes. 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.
