Aortic Endograft Infection: Diagnosis and Management

Area of Science:

• Vascular Surgery
• Infectious Diseases
• Medical Device Complications

Background:

• Aortic endograft infection (AEI) is a rare but severe complication following endovascular aneurysm repair (EVAR).
• Clinical presentations vary widely, from mild symptoms to life-threatening sepsis or aortic rupture.
• Diagnosis relies on clinical findings, lab tests, imaging, and the Management of Aortic Graft Infection Collaboration (MAGIC) criteria.

Purpose of the Study:

• To review the diagnosis, management, and treatment outcomes of aortic endograft infections.
• To highlight the importance of a multidisciplinary approach in managing AEI.
• To discuss graft options and conservative treatment strategies.

Main Methods:

• Review of clinical manifestations, diagnostic criteria (MAGIC), and treatment modalities for AEI.
• Discussion of surgical techniques, including in situ reconstruction versus extra-anatomic bypass.
• Analysis of graft materials, conservative management, and factors influencing treatment outcomes.

Main Results:

• Treatment involves infected endograft removal, aortic reconstruction (often in situ), and antimicrobial therapy.
• Various grafts (biological, prosthetic) are used, each with pros and cons.
• Conservative treatment is an option for high-risk patients without fistulas.
• Outcomes depend on bacterial factors, patient condition (e.g., aortic fistula), and hospital care.

Conclusions:

• AEI requires a multidisciplinary team approach for optimal management.
• Prevention strategies are paramount given the condition's severity.
• In situ reconstruction is frequently preferred over extra-anatomic bypass after infected endograft removal.
