A 77-year-old woman underwent aortic valve replacement and coronary bypass grafting in 2007 in the Emirates. Evolution was uneventful until December 2011. After repeated episodes of unspecific infections, a computed tomographic scan showed a large pseudoaneurysm of the distal ascending aorta. The site of aortic rupture was closed with a Gore-Tex patch and a Staphylococcus aureus infection treated appropriately. Two months later, a small cutaneous lesion on the cranial part of the sternotomy started bleeding. Computed tomographic scan demonstrated recurrence of a false aneurysm with erosion of the sternum and a large subcutaneous hematoma caused by the fistula. The patient was transferred to our institution. The challenges of this case included safe surgical approach (sternotomy, cannulation, perfusion, cerebral protection) as well as complete removal and extensive debridement of the infected material and reconstruction of the aortic arch. Using fully biological material, reconstruction of the ascending aorta and proximal arch was successfully performed.
一位 77 岁的女性于 2007 年在阿联酋接受了主动脉瓣置换和冠状动脉旁路移植术。恢复过程一直很顺利,直到 2011 年 12 月。在反复发生非特异性感染后,计算机断层扫描显示升主动脉远端出现一个大的假性动脉瘤。使用 Gore-Tex 补丁封闭了主动脉破裂部位,并适当治疗了金黄色葡萄球菌感染。两个月后,胸骨切开术的颅顶部分出现一个小的皮肤损伤开始出血。计算机断层扫描显示假性动脉瘤再次出现,胸骨侵蚀,瘘管导致大量皮下血肿。患者被转至我院。该病例的挑战包括安全的手术入路(胸骨切开术、插管、灌注、脑保护)以及彻底清除和广泛清创感染材料和重建主动脉弓。使用完全生物材料,成功地进行了升主动脉和近端弓的重建。
