Abstract
We report a case of descending necrotizing mediastinitis (DNM). DNM is a serious infection, and preventing death requires early diagnosis and draining of the infection focus. An 84-year-old man was admitted to our hospital complaining of a swollen neck and pain when swallowing. He had had a tooth extracted at a neighboring dental clinic 2 days previously. Cervicothoracic computed tomography (CT) scan demonstrated gas bubbles and unencapsulated abscesses in the cervical spaces and anterosuperior and posterior mediastinum, extending below the carina. He was diagnosed as DNM caused by odontogenic infection. Cervical drainage was performed, in addition to mediastinal drainage using video-assisted thoracic surgery (VATS). Complications were sepsis, disseminated intravascular coagulation (DIC), and heart failure after surgery, but he recovered following intensive care. This was a lifesaving case of DNM for which mediastinal drainage was performed with VATS.
