Bacteroides aortitis and aneurysm formation following arteriography

Area of Science:

• Vascular Surgery
• Infectious Diseases
• Radiology

Background:

• Translumbar aortography is an invasive diagnostic procedure.
• Aortitis and aneurysm formation are potential complications.
• Rupture of aortic aneurysms is a life-threatening event.

Observation:

• A middle-aged man developed aortitis, aneurysm formation, and rupture after translumbar aortography.
• The infecting organism was identified as bacteroides.
• Bacteroides is an anaerobe not previously documented in this context.

Findings:

• The case demonstrates a rare but severe complication of translumbar aortography.
• Identification of bacteroides as the causative agent is a novel finding.
• This suggests a broader spectrum of pathogens capable of causing post-procedural aortitis.

Implications:

• Clinicians should consider bacteroides in the differential diagnosis of post-aortography infections.
• Further research is needed to understand the pathogenesis of bacteroides-induced aortitis.
• Enhanced vigilance and diagnostic protocols may be required for patients undergoing translumbar aortography.
