False aneurysm of the ascending aorta concomitant with chronic mediastinitis after tube graft replacement in octogenarian.

An 81-year-old man developed impending rupture of a false aneurysm of the ascending aorta concomitant with chronic mediastinitis lasting for 10 years after tube graft replacement. He had undergone various infection-related mediastinal surgical procedures. He was successfully treated by debridement of infected tissues, patch repair of the false aneurysm, and transposition of the right latissimus dorsi muscle flap. The postoperative course was uneventful except for seromas. A chest computed tomographic scan performed 5 and 24 months after surgery showed no signs of recurrent aneurysm formation. A conservative surgical treatment including muscle flap transposition was effective in octogenarian.
