Recognition of an infected endoluminal aortic prosthesis following repair of abdominal aortic aneurysm: case report and review of the literature.
ABSTRACT 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.

ABSTRACT: A 44-year-old man with an abdominal aortic aneurysm presented with acute pancreatitis with abundant peripancreatic fluid and was successfully treated with endovascular stent graft. Early post-procedural radiological examinations showed air inside the aneurysm sac. Due to the possible infection from pancreatitis, antibiotic treatment was initiated, and he was closely monitored. Serial radiological examinations showed gradual decrease and eventual resolution of air at the end of one month. Follow-up computed tomography 10 months post-implantation revealed no problems. The presence of air inside the aneurysm sac could be a sign of graft infection. Although the air usually resolves spontaneously, close surveillance is necessary for cases with higher risk of infection.Diagnostic and interventional radiology (Ankara, Turkey) 07/2009; 15(2):153-6. · 1.03 Impact Factor

ABSTRACT: Endograft infection has received less attention than other complication, so that little is known about the general features, risk factors, and treatment. The purpose of this short series is to examine our experience of infective complications after EVAR. Between November 2000 and December 2008, 247 patients underwent endograft repair for abdominal aortic aneurysm. Follow-up protocol included clinical visit and computed-tomography angiography 1, 4 and 12 months after the intervention, and yearly thereafter. No duplex control was performed on a regular basis. Median follow-up was 16 months (range, 3-92); two patients (2/244, 0.8%) developed an endograft infection, 12 and 36-months after the intervention respectively. On admission, both patients complained septic-like fever and abdominal discomfort; leukocytes-labelled scans did not reveal pathologic traits whereas spiral computed-tomography confirmed the suspicious of endograft infection. They underwent endograft removal and extra-anatomic axillo-bifemoral by-pass; both survived and are still alive 12 and 6-months after the intervention. Isolated micro-organisms were Candida albicans and Escherichia coli in one patient, and Haemophilus aphrophilus in the other. Endograft infection is an uncommon occurrence, Spiral computed-tomography seems to be an essential diagnostic tool. Graft removal was successful in our high-risk patients. A multicenter registry should be started to define guidelines.International Journal of Surgery (London, England) 02/2010; 8(3):216-20. · 1.44 Impact Factor
