Abstract:
A 55-year-old man was admitted with severe back pain and saccular aneurysm of the descending aorta on computed tomography. Laboratory examinations showed elevated serum C-reactive protein of 16.98 mg/dl. Graft replacement of the descending thoracic aorta was performed on an emergency basis, and a latissimus dorsi muscle flap was wrapped around the implanted graft. Because Streptococcus pneumoniae was detected in the resected tissue, proper antibiotic therapy was administrated. The patient recovered uneventfully, without any sign of infection.
