Mediastinal drainage in descending necrotizing mediastinitis.

Descending necrotizing mediastinitis has been thoroughly described in the past, but we could not find a detailed description of the technique to perform adequate drainage and lavage of all the mediastinal and thoracic spaces. We describe the procedure as we perform it, emphasizing the sites for incision and proper drainage of all the mediastinal compartments and the contralateral thoracic cavity.
