Functional Characteristics of Different Types of Structural Components (Biunites) of Intraorganic Venous Bed in the...

Functional characteristics of different types of spleen venous bed biunites (BU) (by analogy with bifurcation) were studied by digital modeling based on the results of morphometry. Digital models of three different BU types were used: first (D < d_max + d_min), zero (D = d_max + d_min); second (D > d_max + d_min), where D is the diameter of the proximal, d_max and d_min are internal diameters of the distal segments. The ANSYS computer program was used to analyze the hemodynamic resistance and rigidity of the BU structure, and the Vasculograph software was used to analyze the coverage area. It was found that BU can be arranged as follows: by increasing hemodynamic resistance - first, second, and zero type BU; drainage function - second, zero, and first type BU; supporting function - zero, first, and second type BU. Different BU types make unequal contribution to different functions.
