Studies on acute lung lymphatic edema

The outflow from lymphatic vessels running along with the right cardinal bronchus was interrupted in six dogs by the removal of the corresponding hilar lymph nodes. After 6-8 days the right lung showed slight subpleural areas of atelectasis and edema. Edema of endothelial cells of the lung septal capilaries was observed electron-microscopically. This lesion is similar to the findings in cases of mitral stenosis.
