Abstract
Objective: To investigate outcomes of patients with mycotic thoracic aortic aneurysm treated with thoracic endovascular aortic repair (TEVAR) in our hospital. Material and methods: Between March 2012 and November 2013, 5 patients underwent TEVAR. We analyzed bacterial culture results, rates of perioperative complications and mortality. Results: Five patients (3 men, 2 women) had a mean age of 79.6 years (range, 61-98 years). There were no cases with fistula formation between the aorta and the intestine or bronchi. After the diagnosis was made, all patients empirically received broad-spectrum antibiotics. All the patients immediately underwent TEVAR. On blood culture, Bacteroides fragilis, methicillin-sensitive Staphylococcus aureus, penicillin-resistant Streptococcus pneumoniae, Escherichia coli, and Streptococcus agalactiae were identified. Thereafter, specific antibiotic treatment was administered according to culture and susceptibility results and was continued for 6 weeks. The antibiotic treatment was then changed from intravenous to oral form and was continued indefinitely. The postoperative complications included incisional hernia in one case and thoracic hematoma in another case. All the patients remained alive throughout the follow-up duration (mean duration, 15.2 months; range, 7-29 months).
