Aortic Pseudoaneurysm: An Uncommon Consequence of Purulent Pericarditis – A Case Study and Review of Existing Literature

1

Purulent pericarditis is rare in the antibiotic era, but can lead to life-threatening complications like aortic pseudoaneurysm.
2

A 46-year-old man with MRSA purulent pericarditis developed a mycotic pseudoaneurysm of the ascending aorta after surgical intervention.
3

The patient underwent partial pericardiectomy and later thoracic endovascular aortic repair due to a contained aortic rupture.
4

Literature review identified 14 similar cases over 70 years, with Staphylococcus aureus being the most common pathogen.
5

Most patients with aortic pseudoaneurysm following purulent pericarditis required surgical intervention, with a majority surviving.
