RESUMO
The investigation has been performed on 87 corpses of persons of both sex, that died after 60 years of age from the pathology not connected with any diseases in the neck organs. Individual variability in the common carotid artery projection line has been revealed; it conforms, to a certain extent, with the value of the neck index. When the neck is short and thick, the artery position corresponds to the line that runs across the following points: the superior--0.5 cm forward from the mandibular angle, the inferior--0.5 cm medially from the sternoclavicular joint. When the neck index is within the limits 1.71-1.88, it is expedient to draw the classical projection line. When the neck index is within the limits 1.57-1.69, it is possible to determine the projection zone as an elongated rectangle. At the bottom of every side the border of this zone is a straight line drawn between the sternoclavicular joint and the point situating 0.6 cm laterally from the joint, and at the top--the line connecting the top of the mastoid process with the point 1.0 cm behind the mandibular angle.

The method suggested for qualitative estimation of the renal and hepatic vessels perfusion before an injection is based on measuring oscillations of the light beam diffused by the organ's surface (the source--a gas laser of continuous action of red spectrum). An absolute photometer protected by a red filter from external effects of light is used as a registrator. Successive injection of the renal and hepatic vessels with different masses and their investigation by means of roentgenography, preparation, carrosion demonstrate a satisfactory effectiveness of the method presented.

The study of large arteries carried out in 30 corpses and the comparison of the parameters and outlines of these vessels with those recommended in applied hydraulics have shown correspondence between the arteries structure and the principles used for criation of optimal conditions of the liquid current in hydraulics.
