Metabolic effects of long-term diversion of renal venous blood into the portal system.

In 7 splenectomized dogs a left renal vein-splenic vein anastomosis was performed and the right kidney removed. Eighteen to twenty-four months after portalization of renal venous blood no significant alterations of liver function tests were observed. Long-term diversion of renal venous blood into the liver was followed by a slight increase of creatinine and 25-OH-D, a decrease of alpha-amino acid nitrogen in blood plasma and of plasma renin activity in peripheral blood, by signs of slight carbohydrate intolerance despite hyperinsulinaemia, and a slight decrease of erythrocyte count.
