The treatment of infectious aneurysms in the thoracic aorta; our experience in treating five consecutive patients.
The surgical strategy for infected thoracic aortic aneurysms (ITAA) remains controversial. Effective antibiotic therapy is mandatory and surgical intervention is indicated only to prevent an aneurysmal rupture. In-situ reconstruction through an aseptic route is ideal; however, urgent surgery is often required in the uncontrolled infectious phase. Five patients were recently treated surgically for ITAA. They were all males with a mean age of 61.2 (range: 58-66) years. Two patients were operated on urgently in the active infectious phase due to impending aneurysmal rupture. A total arch reconstruction with an extra-anatomical bypass between the ascending aorta and both femoral arteries in one and an extended aortic arch resection with an in-situ graft reconstruction were performed in the other. The other three patients underwent in-situ graft reconstructions in the controlled infectious phase. Four patients had multiple aneurysms, including nine saccular or nodular aneurysms. Short-interval computed tomography (CT) re-examinations revealed a rapid enlargement of the aneurysms and confirmed the diagnosis. All patients successfully survived and are doing well without any evidence of a recurrent aortic infection. The surgical strategy for ITAA should be determined on a case-by-case basis under a careful follow-up with short-interval CT re-examinations.
