Abstract:
Report of a case of a mycotic pseudoaneurysm of the ascending thoracic aorta occurring in the absence of surgical or blunt trauma in a patient who presented with purulent pericarditis. Surgical pericardial drainage was required, which revealed Staphlococcal aureus. Subsequent transesophageal echocardiogram demonstrated a 4 cm x 4 cm pseudoaneurysm of the posterior wall of the aorta above the sinotubular junction. The patient refused surgical correction of the aortic pseudoaneurysm and was successfully managed with antibiotic therapy.
Insights
A rare case of mycotic pseudoaneurysm in the ascending thoracic aorta was successfully treated with antibiotics alone. This finding is significant for patients with purulent pericarditis and Staphylococcus aureus infections.
Area of Science:
- Cardiology
- Infectious Diseases
- Vascular Surgery
Background:
- Mycotic pseudoaneurysms are rare, often associated with trauma or surgery.
- Purulent pericarditis can be a sign of deeper infection, including aortic involvement.
Observation:
- A patient presented with purulent pericarditis and Staphylococcus aureus infection.
- A 4 cm x 4 cm pseudoaneurysm of the ascending thoracic aorta was identified via transesophageal echocardiogram.
- The patient had no history of surgical or blunt trauma.
Findings:
- The aortic pseudoaneurysm was successfully managed non-surgically with antibiotic therapy.
- This case highlights the potential for antibiotic-only management in select mycotic aortic pseudoaneurysm cases.
Implications:
- Non-surgical management with antibiotics may be a viable option for certain mycotic aortic pseudoaneurysms.
- Early diagnosis and targeted antibiotic therapy are crucial for favorable outcomes.
- This case expands the understanding of treatment strategies for ascending thoracic aortic pseudoaneurysms.
