The experimental methods of increasing the vascularity of the liver focus on two types of procedure: (1) creation of perihepatic adhesions1; and (2) arterialization of the portal vein stump after performing an end-to-side portocaval shunt.2 Vineberg's observation3 that implantation of the internal mammary artery into the myocardium will result in collateral circulation has not been experimentally applied to other organs.4,5 The present study was undertaken for investigative purposes in the hope that it might lead to a method of segmental arterialization of the liver in which both a revascularized lobe and control lobes could be evaluated in the same animal.

Method  Ten, large, healthy, greyhound dogs were anesthetized with pentobarbital (27 mg. per kg.). The peritoneal cavity was explored in each instance through a high midline incision under aseptic precautions. A splenectomy was then performed. The splenic artery, or a very large branch of it, was
