title: Management of sterno-mediastinitis.
abstract: With an incidence rate of 1-4%, mediastinitis following cardiac surgery is a rarely occurring complication, but may show a mortality rate of up to 50%. Risk factors for sternal instability are insulin-dependent diabetes mellitus, obesity, immunosuppressed state, chronic obstructive pulmonary disease, osteoporosis, history of radiation, renal failure, body height, smoking and nutritional state. The aim of this paper is to show an overview of this clinical picture, present the risk factors and elucidate the therapy options chronologically. As a result of interdisciplinary cooperation, a therapy concept has developed which is adapted to the patient individually. Therapy begins with the simplest measures and, if deemed necessary, this is then escalated step by step. The aim of the treatment is to bring the infection under control, which requires radical surgical debridement, removal of infected and necrotic tissue, removal of all foreign bodies (including wires and osteosynthesis material) and the removal of all infected, necrotic osseous material if necessary followed by vacuum-assisted closure therapy. The reconstruction of defects of the anterior chest wall is achievable using different muscle flaps. Mostly the muscle pectoralis major is used unilaterally or bilaterally with or without disinsertion of the tendon. Other options are the omental flap, the muscle latissimus dorsi flap or the muscle rectus abdominis flap. A combined approach comprising surgical debridement, short-term vacuum therapy and subsequent myoplastic coverage has proved successful and can be carried out with a high standard of safety.
