Overview
Mediastinitis is inflammation or infection of the tissues in the mid-chest, or mediastinum.[1] This disorder is rare, but is most often observed among patients following chest surgery or endoscopy. Mediastinitis may occur at any age.[2] It may be classified according to cause into 2 groups: acute or chronic (fibrosing). Acute mediastinitis is usually bacterial and due to rupture of organs in the mediastinum. Chronic sclerosing (or fibrosing) mediastinitis, while potentially serious, is caused by a long-standing inflammation of the mediastinum, leading to growth of acellular collagen and fibrous tissue within the chest and around the central vessels and airways. Life threatening causes of mediastinitis include esophageal perforation. Common causes of mediastinitis trauma, beta-hemolytic streptococcus, forceful or constant vomiting and median sternotomy. If left untreated, fibrosing mediastinitis may progress into sepsis and subsequently, death. The presence of mediastinitis among patients following chest surgery is observed to have a particularly poor prognosis; there is a serious risk of death.[3] Common complications of mediastinitis include sepsis and spread of the infection. Symptoms of mediastinitis include chest pain, malaise, and shortness of breath[4] Common physical examination findings of mediastinitis include clinical signs of sepsis, tachycardia, and tachypnoea[5]. CT Scan is the preferred imaging of choice for diagnosis of mediastinitis. Mediastinitis is characterized by the presence of calcified mediastinal mass. The mainstay of therapy in acute mediastinitis secondary to cardiothoracic surgery includes Clindamycin and Ceftriaxone. The preferred regimen for preoperative prophylaxis against acute mediastinitis includes either a second generation Cephalosporin or Vancomycin. Aggressive surgical debridement is the recommended among patients with descending necrotizing mediastinitis.
