[Pulmonary edema due to shock, fat embolism, disseminated intravascular coagulation and post extracorporeal circulation].

The appearance of lesional edema in the region of the alveolar wall constitues the initial phenomenon of involvement of the pulmonary parenchyma during shock lung, fat embolism, DIC and post perfusion lung syndrome. The alveolar septum reacts in a monomorphous manner to these various agressions, although the responsible physiopathological factors are numerous and varied. The lung in E.C.C. represents a vertiable experimental post-agressive lung. It has been studied in man from the clinical, radiological, hemodynamic and anatomopathological standpoints. The modifications found enable one to better understand the etiological factors intervening in the other post-agressive lungs.
