Early Pulmonary Pathology after Bullet Injury on Hind Legswith Bone Fracture in Dogs / 第三军医大学学报

ABSTRACT

The pathological changes of the lungs in 16 dogs with blulet-caused fracture of the hind legs were studied. Under light microscopy, the pathological features were marked capillary congestion, extravasation of red cells in either the interstitium or alveolar spaces, atelectasis, leucocyte infiltration of the interstitium, mild pulmonary edema, and fat emboli in the small vessels. These changes, with the exception of fat embolism, were found to occur 2 hours after injury, and were fully developed around 24 hours. Then fat embolism supervened. Most of the changes gradually subsided and disappeared as time went by.The results of this study indicate that there can be pathological lesions in the lungs secondary to the bullet-induced fracture of the hind legs in dogs.
