In situ prosthetic graft replacement for mycotic thoracoabdominal aneurysms.
Infected aortic aneurysms remain a difficult surgical problem associated with high morbidity and mortality. We report three cases of mycotic thoracoabdominal aneurysms treated by debridement of infected aortic tissue, in situ prosthetic graft replacement, and intensive antibiotic therapy. One early death occurred in a patient with systemic sepsis related to Salmonella enteritidis infection of the thoracic aorta secondary to a colovesical fistula. The two other patients remain alive at 2 years without further complications of the surgery. Bacteriology is as follows: Staphylococcus aureus, Streptococcus pneumoniae, and Salmonella enteritidis. In all patients the operation was performed immediately after the diagnosis was confirmed. Antibiotic therapy was begun intraoperatively and was continued for at least 6 months. Two patients were followed regularly, and there have been no septic recurrences in our 2-year follow-up period. In situ prosthetic graft replacement in conjunction with intensive antibiotic therapy is a viable option in the treatment of mycotic thoracoabdominal aortic aneurysms.
