[The normal ultrastructure of the erythrocytes and in experimental portal hypertension].
Erythrocyte types were studied in portal and femoral veins blood in intact dog and in the experimental portal hypertension under scanning electron microscope. Three basic types (discoid, polygonal and spherocyte) were distinguished. Analysis of the material obtained confirmed the suggestion on the existence of stable erythrocyte types both in normal conditions and pathology. Content of these types in blood of vessels named is different. Inferior caval vein system is inaccessible for erythrocytes with significantly altered shape because they are unable to penetrate liver sinusoids. In portal hypertension essential increase of these erythrocytes number occurs and they are encountered in femoral vein blood. These forms obviously pass into the general blood flow through multiple collaterals. One of the criteria for portal hypertension diagnostics is suggested so as the method of evaluating portal vein shunts in conditions of the formed collateral blood stream.
