Ultrasonography was performed on 21 young dogs with portacaval shunts. Initial ultrasonography revealed a small hypovascular liver in all dogs. Eight portacaval shunts (4 intrahepatic, 4 extrahepatic) were detected. Supplementary ultrasonography of dogs under general anesthesia and subjected to positive-pressure ventilation identified 6 additional intrahepatic portacaval shunts.
