OBJECTIVE: To evaluate the epidemiological and clinical aspects of acute mediastinitis and to characterize its treatment. METHODS: A retrospective study conducted through review of the medical charts of patients diagnosed with acute mediastinitis at the Hospital Escola da Faculdade de Medicina do Triângulo Mineiro (Triângulo Mineiro Medical School Hospital) between 1987 and 2004. RESULTS: A total of 21 patients were studied. Most (76.2%) were male, and the mean age was 52.5 years. Six patients (28.6%) died. The most common cause (in 38.1%) was median sternotomy, followed by esophageal perforation (in 33.3%) and cervical infection (in 14.3%). Staphylococcus aureus and Staphylococcus epidermidis were the causative agents most frequently isolated. In most cases, the treatment of choice was antibiotic therapy accompanied by surgery. The most frequent complications of the acute mediastinitis were pleural effusions (in 23.8%) and osteomyelitis (in 19.0%). The average hospital stay was 26.6 days. CONCLUSION: Acute mediastinitis is a serious complication of some diseases and procedures. Despite its low incidence, the mortality rate is high. Staphylococcus aureus and Staphylococcus epidermidis are the most common causative agents. The treatment used was antibiotic therapy accompanied by surgery.
