RESUMO
The hemorrheological changes were observed in 7 cases with portal hypertension after they were operated on with distal splenocaval shunt (DSCS). Similar cases with splenecto-my served as controls. It was found that blood hyperviscosity was slightly decreased after DSCS and the deformability of erythrocytes was improved from 7 to 14 days after DSCS. But blood hyperviscosity was significantly increased in the cases after splenectomy. Blood hyperviscosity was lower in the cases with DSCS than in those with splenectomy. Blood hyperviscosity , expressed mainly by the aggregation rate and deformability of erythrocytes, platelet count, etc, is dependent on the spleen. Since the spleen is preserved in DSCS so blood hyperviscosity is slightly decreased and complications due to blood hyperviscosity may be less in number after DSCS.
