Summary
Primary infected aorto-iliac aneurysms present a diverse range of causative pathogens, wider than previously recognized. Surgical outcomes varied, with in situ revascularization showing lower mortality than extra-anatomic bypass.
Area of Science:
- Vascular Surgery
- Infectious Diseases
- Microbiology
Background:
- Primary infected aorto-iliac aneurysms are rare but serious conditions.
- Understanding the causative pathogens and surgical outcomes is crucial for effective management.
Purpose of the Study:
- To assess the causative pathogens and surgical outcomes in patients with primary infected aorto-iliac aneurysms.
- To identify trends and factors influencing patient prognosis.
Main Methods:
- Retrospective study of 26 patients treated at a university hospital between 1992 and 2009.
- Analysis of causative organisms, treatment strategies (in situ vs. extra-anatomic bypass), and patient outcomes.
- Inclusion of demographic data, clinical presentation, and follow-up complications.
Main Results:
- The study identified a broad spectrum of causative organisms, including Campylobacter fetus, Streptococcus pneumoniae, and Listeria.
- 22 patients were symptomatic, with 13 presenting with ruptured aneurysms.
- Hospital mortality was 23%, with higher rates in the extra-anatomic bypass group (66.7%) compared to the in situ group (17.4%).
- Six vascular complications (30%) occurred during follow-up in survivors.
Conclusions:
- The bacteriological spectrum of primary infected aorto-iliac aneurysms is more diverse than previously reported.
- Increased availability of diagnostic tests and a higher prevalence of immunosuppression may contribute to this broader spectrum.
- In situ revascularization appears to be associated with better survival outcomes compared to extra-anatomic bypass.

Aneurysm III: Interprofessional Care
Aneurysm management involves either conservative medical therapy or surgical intervention, depending on the size and symptoms of the aneurysm. Conservative management is generally reserved for smaller, asymptomatic aneurysms, while larger or symptomatic aneurysms often necessitate surgical repair.Conservative Medical TherapyFor small, asymptomatic aneurysms, particularly abdominal aortic aneurysms (AAA) less than 5.5 centimeters in diameter, conservative medical therapy is recommended. This...
Aneurysm I: Introduction
An aortic aneurysm is a localized outpouching or dilation at a weak point in the artery wall. It may involve different parts of the aorta, such as the abdominal aorta, aortic arch, or thoracic aorta.Etiological factorsSeveral disorders are associated with aortic aneurysms.Congenital causes, such as primary connective tissue disorders like Marfan syndrome, impact the integrity and strength of connective tissues, notably affecting the aorta. Marfan syndrome is a genetic disorder that specifically...
