Abstract:
A 77-year-old man had clinical and radiologic signs of graft infection develop 1 year after stent grafting for abdominal aortic aneurysm. Blood cultures grew Bacteroides fragilis, and cultures of the aneurysm sac grew Enterococcus. The patient's condition was successfully managed with staged extraanatomic revascularization followed by graft excision. Although stent graft infection to date is extremely rare, some aspects peculiar to the placement of these devices potentially could increase their susceptibility to infection. Recognition and standard techniques in management can lead to successful outcome.
Insights
Graft infection after abdominal aortic aneurysm stent grafting is rare but possible. Successful management involves staged revascularization and graft excision, highlighting the importance of prompt recognition and standard treatment techniques.
Area of Science:
- Vascular Surgery
- Infectious Diseases
- Medical Device Technology
Background:
- Abdominal aortic aneurysm (AAA) repair using endovascular stent grafts is a common procedure.
- Graft infection following endovascular aneurysm repair (EVAR) is a rare but serious complication.
- Early recognition and appropriate management are crucial for successful patient outcomes.
Observation:
- A 77-year-old male patient presented with clinical and radiological evidence of graft infection one year post-EVAR for AAA.
- Blood cultures identified Bacteroides fragilis, and aneurysm sac cultures revealed Enterococcus species.
- The patient underwent a staged treatment approach involving extraanatomic revascularization followed by graft excision.
Findings:
- The patient's graft infection was successfully treated with a staged surgical strategy.
- The specific placement of stent grafts may present unique factors contributing to infection susceptibility.
- Bacteroides fragilis and Enterococcus were the identified pathogens in this case.
Implications:
- This case underscores the potential for rare complications like stent graft infection after EVAR.
- Standard surgical techniques for infection management can be effective even in complex cases.
- Further research into device-related factors influencing infection risk in EVAR is warranted.
