[Arterial revascularization of the liver after portacaval shunt in the rabbit]

A new experimental model has been employed as part of research into portosystemic encephalopathy, namely end-to-side portacaval shunt associated wih revascularization of the portal bed with the right renal artery in the rabbit. Study of the changes brought on by the operation is based on the evaluation of survival, the behaviour of the weight curve, the weight liver-body/weight ratio, and the angiographic and histologic pictures. Significant variations were obtained by comparison with animals in which an associated portocaval shunt was performed.
