Favorable Conservative Management of a Rare Primary Aortitis Secondary to Listeria Monocytogenes: Case Report and Review of the Literature

Endovascular Aortic Repair for a Symptomatic Mycotic Aneurysm With Listeria monocytogenes: A Case Report

PURPOSE

To report a case of successful endovascular aortic repair for a symptomatic mycotic abdominal aortic aneurysm infected with Listeria monocytogenes.

CASE REPORT

We report the case of an 88-year-old woman who presented with acute abdominal pain and vomiting. Approximately a year prior to her presentation, the patient was diagnosed with a mycotic abdominal aortic aneurysm with Listeria monocytogenes and was treated conservatively for more than 2 months at another hospital. At our hospital, contrast-enhanced computed tomography revealed an abdominal aortic aneurysm and an aneurysm of the left internal iliac artery. Endovascular aortic repair was performed successfully. At 16 months after the surgery, the patient remained asymptomatic on long-term antibiotics, and there was no enlargement of the aneurysm.

CONCLUSION

Endovascular aortic repair and lifelong antibiotics may be an alternative therapy for mycotic abdominal aortic aneurysms. However, the risk of recurrent infection is high and warrants long-term follow-up.
