Abstract

Ascending aorta mycotic aneurysm is a rare entity. It is a life-threatening condition because of the possibility of aortic dissection, or rupture. Escherichia coli is recognised as an uncommon cause of aortic mycotic aneurysm. An 81-year-old woman with a history of Escherichia coli pyelonephritis 4 months previously, was admitted to our centre for a mycotic aneurysm of the ascending aorta caused by Escherichia coli. She was successfully treated by urgent in situ replacement of the ascending aorta with a cryopreserved homograft, combined with antibiotics. Although infrequent, Escherichia coli mycotic aneurysm should be suspected in older patients with atherosclerosis and who developed septicaemia. Prompt treatment with a combination of appropriate antibiotics and surgery is required.

摘要

升主动脉真菌性动脉瘤是一种罕见实体。由于主动脉夹层或破裂的可能性，这是一种危及生命的情况。大肠杆菌被认为是主动脉真菌性动脉瘤的罕见病因。81 岁女性， 4 个月前有大肠杆菌肾盂肾炎病史，因大肠杆菌引起的升主动脉真菌性动脉瘤入院。通过使用冷冻保存的同种移植物并结合抗生素紧急原位置换升主动脉，她获得了成功治疗。虽然不常见，但大肠杆菌患有动脉粥样硬化和出现败血症的老年患者应怀疑真菌性动脉瘤。需要结合适当的抗生素和手术进行及时治疗。
