В качестве объектов для исследования использовали виртуальные (цифровые) модели разного типа биюнитов ВВРС, основанные на ранее полученных их морфометрических характеристиках. Выделяли биюниты ВВРС 4 типов: 1 тип - полная асимметрия, диаметр проксимального сегмента (D) не равен диаметрам большего (dmax) и меньшего (dmin) дистального сегмента D≠dmax≠dmin, 2 тип - боковая асимметрия, D=dmax, D≠dmin, 3 тип - односторонняя симметрия, D≠dmax, dmin=dmax, 4 тип - полная симметрия, D=dmax=dmin. Для анализа проводящей функции (гемодинамическое сопротивление) и опорной (жесткость конструкции) виртуальных моделей биюнитов ВВРС разного типа применяли компьютерную программу ANSYS Student. Анализ дренирующей функции виртуальных моделей разного типа биюнитов ВВРС проводили с использованием компьютерной программы Vasculograph.</p></sec><sec><title>Результаты</title><p>Результаты. Установлено, что в направлении увеличения значения показателя, характеризующего 1) гемодинамическое сопротивление, биюниты ВВРС разного типа расположились следующим образом: 1-го типа, 2-го типа, 3-го типа и 4-го типа; 2) дренирующую функцию: 4-го типа, 2-го типа, 3-го типа и 1-го типа; 3) опорную функцию: 4-го типа, 3-го типа, 2-го типа и 1-го типа.</p></sec><sec><title>Заключение</title><p>Заключение. Разного типа биюниты ВВРС в неравной степени принимают участие в выполнении проводящей, дренирующей и опорной функций. Основная роль в выполнении функций по проведению крови, дренированию ткани селезенки и созданию «мягкого скелета» органа принадлежит биюнитам ВВРС 1-го типа. В качестве морфометрического эталона нормы ВВРС можно использовать морфометрические характеристики биюнитов 1-го типа.</p></sec></abstract><trans-abstract xml:lang="en"><p>Objective - to establish functional (conducting, draining, pillar) properties of different types of structural components (biunites) of splenic venous vasculature by their numerical modelling based on the results of morphometry.</p><sec><title>Materials and methods</title><p>Materials and methods. Virtual (digital) models of different types of splenic venous biunites based on their morphometric characteristics obtained earlier were used as objects for the study. We distinguished 4 types of splenic venous biunites: 1 type - complete asymmetry, the diameter of the proximal segment (D) is not equal to the diameters of the larger (dmax) and smaller (dmin) distal segment D≠dmax≠dmin, 2 type - lateral asymmetry, D=dmax, D≠dmin, 3 type - unilateral symmetry, D≠dmax, dmin=dmax, 4 type - complete symmetry, D=dmax=dmin. ANSYS Student computer program was used to analyse the conductive function (haemodynamic resistance) and pillar function (structural rigidity) of virtual models of different types of splenic venous biunites. The drainage function of virtual models of different types of splenic venous biunites was analysed using the Vasculograph computer program.</p></sec><sec><title>Results</title><p>Results. It was found that in the direction of increasing the value of the index characterising 1) hemodynamic resistance biunites of different types of splenic venous vasculature were arranged as follows: 1st type, 2nd type, 3rd type, and 4th type; 2) draining function: 4th type, 2nd type, 3rd type and 1st type; 3) pillar function: 4th type, 3rd type, 2nd type and 1st type.</p></sec><sec><title>Conclusion</title><p>Conclusion. Different types of splenic venous biunites take part in fulfilment of conducting, draining and pillar functions to an unequal extent. The main role in fulfilment of the functions of blood conduction, drainage of the spleen tissue and creation of the "soft skeleton" of the organ belongs to type 1 splenic venous biunites. The morphometric characteristics of type 1 biunites can be used as a morphometric standard of the splenic venous norm.</p></sec></trans-abstract><kwd-group xml:lang="ru"><kwd>cелезенка</kwd><kwd>морфометрия</kwd><kwd>венозное русло</kwd><kwd>структурный компонент - биюнит</kwd></kwd-group><kwd-group xml:lang="en"><kwd>ru</kwd><kwd>en</kwd></kwd-group></article-meta></front><back><ref-list><title>References</title><ref id="cit1"><label>1</label><citation-alternatives><mixed-citation xml:lang="ru">Jones C.
