Abstract
Angiography was performed before and after construction of end-to-side portacaval shunts in 10 cirrhotic patients. In comparison to preoperative angiograms, postoperative studies demonstrated: 1. Increased diameter of the hepatic artery and its branches; 2. Increased incidence of collateral circulation from the superior mesenteric artery; 3. Decreased size of the liver; 4. Increased or unchanged size of the splenic artery; 5. Decreased size of the spleen. Arterioportal flow was seen in about two-thirds of patients. In two patients, orthograde flow was present in the hepatic limb of the portal vein, indicating parahilar arterioportal communications. Parahilar collateral vessels were actually demonstrated in one case, and may represent markedly dilated vasa vasorum of the portal vein. In some other patients, retrograde flow was present in the portal vein indicating peripheral arterioportal communications. After end-to-side portacaval shunts were performed in three dogs, arterioportal communications were demonstrated centrally or peripherally.
