[Surgical Treatment for Mycotic Aortic Aneurysms]

Mycotic aortic aneurysms are relatively rare. Diagnosis and treatment may sometimes be difficult. We have treated 5 cases of mycotic aortic aneurysms in our institution. The patients were 4 males and 1 female with a mean age of 65.6±16.7 years old. All patients had vascular diseases and complained of fever. Preoperative blood cultures were positive in 4 cases. The strategy for treatment of mycotic aortic aneurysms consisted of removal of infective focuses as much as possible and revascularization using an artificial graft combined with omentopexy. Administration of antibiotics was continued for 6 months. All patients have been alive without recurrence of infections for a mean period of 22.6 months, which was considered to be an acceptable result. Artificial graft replacement combined with omentopexy and long-term administration of antibiotics is suggested to be useful for the treatment of mycotic aortic aneurysms.
