Summary
Aortic stent graft infections are rare but serious complications. Surgical removal with in situ reconstruction offers the best outcomes for patients with infected aortic stent grafts.
Area of Science:
- Vascular Surgery
- Infectious Diseases
- Medical Device Complications
Background:
- Aortic stent graft infection is an uncommon complication, often reported in single cases.
- Understanding its frequency, risk factors, and optimal treatment is crucial for patient outcomes.
Purpose of the Study:
- To determine the incidence, risk factors, and current treatment strategies for aortic stent graft infections.
- To evaluate outcomes associated with different treatment modalities.
Main Methods:
- Literature review and contact with specialized centers performing endovascular aortic repair.
- Analysis of 65 identified cases (43 reported, 22 unpublished).
- Data collection on patient demographics, procedure details, infection characteristics, and treatment outcomes.
Main Results:
- The overall frequency of infection was 0.43% (65 cases).
- Staphylococcus aureus was the most common pathogen (54.5%).
- Surgical treatment (82%) with in situ reconstruction showed lower mortality (5.8%) compared to extraanatomical bypass (16%).
Conclusions:
- Aortic stent graft infection is uncommon with unclear risk factors.
- Complete surgical excision and in situ reconstruction yield the best outcomes.
- A multicenter registry is recommended to further investigate these complications.
