Incidental discovery of mycotic aortic aneurysm presenting after blunt trauma

Mycotic aortic aneurysms pose a unique surgical challenge, with operative management dependent on patient factors and institutional capabilities. In an infected surgical field, cryopreserved aortic homograft (CAH) can provide a durable and infection-resistant repair. We present the case of a 48-year-old male with a mycotic abdominal aortic aneurysm, confounded by an initial diagnosis of blunt abdominal aortic injury. Endovascular aneurysm repair was performed; however, subsequent rapid mycotic degeneration elucidated an infectious component. The patient then underwent explantation of the infected graft with in-line reconstruction via CAH. He has demonstrated clinical stability and graft patency at 16 months postoperatively.
