ABSTRACT
There are reported the results of certain measurements made on 158 human cadavers of both sexes. A series of main parameters are given, such as the distance between the superior mesenteric vein and on the one hand its confluence with other vessels and on the other hand the pancreas and the horizontal part of the duodenum: the distance between the superior mesenteric vein together with the portal vein, and the inferior caval vein; the diameters of the portal trunk and the confluence angle between the roots of the portal vein. The results reflect the possibility to perform a troncular portocaval anastomosis in at least 90 per cent of the cases. The authors' attention was, however, directed towards the anatomy of the superior mesenteric vein, as this vessel is preferred by some surgeons in the achievement of the portocaval anastomosis.

The authors studied the ratio between the density of the Haversian canals and the area occupied by these in the diaphyseal cortex of the main long bones in man. The interrelation was estimated by means of the correlation coefficient, which varies between -0.135 for the fibula and -0.168 for the humerus. It was found that the two parameters were inversely proportional: the greater the number of canals in a given area, the smaller the relative proportion of the area occupied by them.
