[Mycotic descending thoracic aortic aneurysm complicated by pyothorax postoperatively: report of a case].

: We experienced with a case of mycotic descending thoracic aortic aneurysm (MTAA) complicated by pyothorax postoperatively. The graft replacement accompanied with wrapping by omental pedicle flap (OPF) was performed in this case. We considered that causative organism for MTAA was Salmonella species, and discussed effectiveness of the application of OPF to MTAA.
