A Case Report of Mediastinitis after Subtotal Graft Replacement of the Thoracic Aorta / 日本心臓血管外科学会雑誌

ABSTRACT

A 57-year-old man underwent subtotal graft replacement of the thoracic aorta for aneurysms of both the ascending and descending aorta. On the 20th post-operative day, pus was found to be draining from the sternotomy wound. The wound was opened and irrigated with 2% Povidoneiodine solution for a total of 3 months. Culture of the pus from the irrigation revealed <i>Staphylococcus epidermidis</i>. When there were no clinical indications of infection and wound cultures were negative, the necrotic sternum and surrounding tissue were debrided and an omental graft was placed in the cavity. Upon follow-up examination, the patient is doing well 10 months after the initial surgery.
