Recognition of an Infected Endoluminal Aortic Prosthesis Following Repair of Abdominal Aortic Aneurysm: Case Report and Review of the Literature

Presentation of an infected endoaortic stent graft may be different from those with open aortic reconstruction and may be difficult to recognize. We report a case of an infected endoaortic stent graft for treatment of an abdominal aortic aneurysm (AAA). In this case, clinically significant endograft infection was not apparent on the initial computed tomography (CT) scan, however, serial CT scans demonstrated progressive AAA enlargement with increased inflammation. The white blood cell scan documented enhancement throughout the infrarenal aorta. The patient’s condition was managed with total explantation of the endograft, AAA resection, and reconstruction with a cryopreserved aortic homograft. This report reviews the presentation, radiographic findings, and diagnosis of as well as literature on infected endoaortic stent grafts.
