Mediastinitis due to Gordona sputi after CABG.

Genus Gordona is included in mycolic acid containing bacteria. This genus infection is very rare and occurs classically in immuno-compromised patients. We report a patient who developed mediastinitis due to Gordona sputi after coronary artery bypass grafting (CABG) using left internal mammary artery. Immunocompromised factors were not noticed in this case but postoperative bleeding, the most important risk factor of mediastinitis, was found in his course. The treatment was antibiotic therapy, surgical soft tissue debridement and open irrigation with dilute povidone-iodine solution. However, infectious reaction continued and Gordona sputi repeated cultured from wound. Next procedure, debridement of sternal bone and omental transfer, was performed and skin was closed primarily. Inflammatory reaction was attenuated and the wound was healed Broad debridement and omental transfer were very effective for mediastinitis due to Gordona sputi after CABG.
