[Roentgenogrammetry of the spleen and its vessels under normal conditions and in disorders of visceral hemodynamics (based on angiographic studies)].
Based on an analysis of the angiograms of 304 patients broken down into groups by the nosological principle, a system of x-ray parameters exactly describing the normal spleen was developed. The 3 main forms of the spleen, differing significantly (P less than 0.001) in some mathematically substantiated criteria, were singled out. In analysing the angiograms of 222 patients with portal hypertension of various degree it was shown that the presence of portal hypertension including its subclinical forms can be established on the basis of a changed complex of proposed criteria. Simplified ways to calculate the area of the spleen shadow and the voluminous splenic blood flow were worked out. The data obtained can be used for a visual analysis of the angiograms as well as for computerized diagnosis of hepatic and pancreatic diseases.
