A comparison of the effects of end-to-side portacaval shunting and side-to-side mesocaval shunting on hepatic haemodynamics in the dog.
Functional liver blood flow and hepatic artery flow were measured before and after either end-to-side portacaval or side-to-side mesocaval shunting in dogs. Functional liver blood fell by approximately 50% following both portacaval and mesocaval shunting. The hepatic artery response was variable after both portacaval and mesocaval shunts. It is concluded that side-to-side mesocaval shunts do not preserve hepatic blood flow or produce a greater compensatory increase in hepatic artery flow than conventional portacaval shunts.
