Abstract
Summary
1. A successful technic for individual ligation and division of the hepatic veins in the dog is described. 2. Complete occlusion of the hepatic veins is uniformly fatal in dogs. However, if a porta-caval shunt is also done, the dogs will survive. 3. Fifteen dogs prepared in this manner were studied, and 66% of them developed a significant elevation of the portal pressure. 4. Ascites developed in 53% of the dogs, but the ascites could not be correlated with the increased portal pressures, decreased serum proteins, or pathological changes in the liver.
