Overview
Infection of an artery, often referred to as arterial infection or mycotic aneurysm, involves microbial invasion leading to inflammation and potential complications such as thrombosis, pseudoaneurysm formation, and systemic sepsis 1.Diagnosis
Clinical Presentation: Fever, localized pain, swelling, and signs of systemic infection 1.
Imaging: Contrast angiography and CT/MRI angiography to visualize arterial involvement and complications 1.
Laboratory Tests: Elevated inflammatory markers (CRP, ESR), blood cultures to identify causative organisms 1.Management
Antibiotics: Broad-spectrum initially, tailored based on culture and sensitivity results 1.
Surgical Intervention: Debridement, resection of infected segment, and vascular reconstruction when necessary 1.
Endovascular Approaches: Used for less invasive management, particularly in complex cases where open surgery is contraindicated 1.Special Populations
Pregnancy: Limited data; management focuses on balancing maternal and fetal safety with aggressive antibiotic therapy and surgical intervention when needed 1.
Pediatrics: Tailored antibiotic therapy and surgical interventions adapted to pediatric anatomy and physiology 1.
Elderly: Consider comorbidities; prioritize minimally invasive techniques to reduce surgical risks 1.
Comorbidities: Presence of diabetes, immunosuppression, or chronic vascular disease necessitates meticulous infection control and tailored antibiotic therapy 1.Key Recommendations
Utilize imaging techniques such as contrast angiography and CT/MRI angiography for definitive diagnosis and assessment of arterial infection complications (Evidence: Moderate 1).
Initiate broad-spectrum antibiotic therapy promptly, adjusting based on culture and sensitivity results (Evidence: Moderate 1).
Consider endovascular interventions as a viable alternative to open surgery for managing arterial infections, especially in complex cases (Evidence: Expert opinion 1).References
