Aortic Endograft Infection by Pasteurella multocida: A Rare Case

Area of Science:

• Vascular Surgery
• Infectious Diseases
• Medical Device Complications

Background:

• Infection of aortic endografts is a rare but serious complication after endovascular aneurysm repair (EVAR).
• Standard treatment involves graft explantation and extra-anatomic bypass to restore blood flow and control infection.
• This approach carries significant morbidity and mortality risks.

Observation:

• A case of Pasteurella infection involving an aortic endograft is presented.
• The patient presented with symptoms indicative of endograft infection.
• The infection was localized to the aortic endograft.

Findings:

• The aortic endograft infection was successfully managed nonoperatively.
• Percutaneous drainage was employed to achieve source control.
• The infected endograft was preserved, avoiding explantation and bypass.

Implications:

• Nonoperative management, including percutaneous drainage and graft preservation, may be a viable alternative for select aortic endograft infections.
• This approach could potentially reduce the morbidity and mortality associated with traditional surgical interventions.
• Further research is warranted to establish the safety and efficacy of nonoperative strategies for endograft infections.
