LUNG - Adult respiratory stress syndrome

The outer surface of this portion of lung shows a 4 cm. area of fibrin. The cut surface shows that the lung is solid and is mottled by yellowish areas which stand out from the grey-blue background. Microscopically there was extensive intra-alveolar fibrosis and thickening of the alveolar walls with capillary congestion and intramural haemorrhage.
The patient was delivered of twins approximately a month before she died. Before delivery there was a history of toxaemia; after delivery there were retained products of conception; she developed a disseminated intravascular coagulation and infarction of the small intestine. She was treated for septicaemia and disseminated intravascular coagulation but developed respiratory failure. Death occurred in respiratory failure. This is one of the manifestations of the lung changes in shock due to a number of causes. See Journal of Clinical Pathology, 1980, 33; 891.
