title: [Significance of the characteristics of the aortic branching in regulating human regional blood flow].
abstract: After certain reconstructive vascular operations which concern the connection of two major arteries, in a number of cases the "steal syndrome" appears--interdependence of the volumetric blood stream passing through the connected arteries resulting from an artificially made too narrow a common trunk of the two arteries. The fluid expense, when it moves along the anatomical preparation of the aorta and its branches, demonstrates that there occurs a definite interdependence of the fluid expense in the major arteries at the branching coefficient K greater than 1. Calculation of the branching coefficient in the aorta at various levels performed in 25 human corpses reveals, in some cases K greater than 1. It can cause the interdependence between the volumetric blood stream and the vascular tonus in the neighbouring vascular regions in patients suffering from disturbances of some compensatory processes.
