A New Murine Model of Endovascular Aortic Aneurysm Repair

[Infected aneurysms of the aorta]
Abstract:
Mycotic aneurysms, a quite rare syndrome, are classified into three groups: primary (the most frequent one), secondary to bacterial endocarditis, and secondary to direct inoculation (infections focus or trauma). Primary aneurysms are related to bacteremia with bacterial setting of an atheromatous lesion, most often. Clinical presentation is often misleading or delayed from infectious process. However, presence of clinical aneurysm, pain, and infectious syndrome should suggest diagnosis and lead to immediate antibiotic therapy and rapid surgical management, as rupture of the aneurysm is a frequent, serious and ineluctable complication. Importance of microbiologic search is to be emphasized as the diversity of the responsible microorganisms is very high; waiting for bacteriological results, a bactericidal double antibiotherapy should be instituted.
Insights
Mycotic aneurysms are rare infections of arteries, often presenting with misleading symptoms. Prompt antibiotic therapy and surgical intervention are crucial to prevent life-threatening rupture.
Area of Science:
- Cardiovascular Medicine
- Infectious Diseases
- Vascular Surgery
Background:
- Mycotic aneurysms are rare vascular infections, classified into primary, secondary to endocarditis, or direct inoculation.
- Primary mycotic aneurysms typically arise from bacteremia seeding an atheromatous lesion.
- Clinical presentation can be delayed or misleading, complicating early diagnosis.
Purpose of the Study:
- To review the classification, clinical presentation, diagnosis, and management of mycotic aneurysms.
- To emphasize the importance of early recognition and intervention to prevent catastrophic rupture.
- To highlight the broad spectrum of causative microorganisms and the need for prompt microbiological investigation.
Main Methods:
- Review of literature on mycotic aneurysm classification and pathogenesis.
- Analysis of clinical presentations, diagnostic challenges, and treatment strategies.
- Emphasis on microbiologic diagnosis and empirical antibiotic selection.
Main Results:
- Mycotic aneurysms require urgent diagnosis and management due to high rupture risk.
- Early signs include clinical aneurysm, pain, and infectious syndrome.
- Broad-spectrum bactericidal antibiotics and surgical repair are indicated.
Conclusions:
- Mycotic aneurysms necessitate a high index of suspicion for timely diagnosis.
- Immediate antibiotic therapy and surgical intervention are critical for favorable outcomes.
- Comprehensive microbiologic evaluation guides definitive antimicrobial treatment.
