Работа выполнена на аутопсийном материале 55 людей, умерших в возрасте от 25 до 89 лет, не имевших к моменту смерти патологических изменений в стенке исследованной БПВ. С целью выявления изменений в стенке БПВ у лиц разных возрастных групп при варикозной болезни изучены фрагменты вен, удаленных во время флебэктомии у 80 пациентов варикозной болезнью. Изучение ОД структурных компонентов у лиц разных возрастных групп показало, что объем внутренней оболочки - (далее - tunica intima - TI) и объем капиллярной сети в средней оболочке (далее - tunica media - TM) с возрастом снижались, в то время как объем мышечного компонента в циркулярном слое TM с увеличением возраста пациентов не изменялся, а содержание продольных пучков гладких мышечных клеток в наружной оболочке (далее tunica externa - TE) - нарастало. Исследование изменений сосудисто-тканевых отношений в стенке БПВ у лиц разных возрастных групп показало, что в норме степень васкуляризации циркулярного слоя TM выше, чем в TE. При варикозной болезни имеет место увеличение ОД TI в молодом и зрелом возрасте, что свидетельствует о нарастании признаков фиброза, а снижение объемной доли TI в пожилом и старческом возрасте указывает на прогрессирование склеротических изменений. В отличие от нормы во всех возрастных группах при варикозной болезни в структуре TM количественные изменения исследованных нами признаков переходят в качественные. В циркулярном слое TM снижение доли циркулярноориентированных пучков гладких мышечных клеток сопровождается нарастанием соединительнотканного матрикса, доля объема которого повышается с возрастом пациентов. Таким образом, полученные нами данные показали, что с возрастом в стенке БПВ при варикозной болезни нарастают морфологические изменения, способствующие эндотелиальной дисфункции, что может являться одним из факторов образования тромбов, также снижается доля структур с сократительной функцией в TM, что приводит к венозному застою в бассейне БПВ.</p></abstract><trans-abstract xml:lang="en"><p>The purpose of this study is to assess the extent of morphological changes in the structural components of the great saphenous vein in individuals of different age groups in norm and in varicose veins by morphometry of their volume fractions. The work was performed on autopsy material of 55 people who died at the age of 25 to 89 years, who had no pathological changes in the wall of the examined of the great saphenous veins at the time of death. To study of changes in the wall of the great saphenous vein in individuals of different age groups in varicose disease, fragments of veins removed during phlebotomy in 80 patients with varicose veins were used. The study of volume fractions structural components in individuals of different age groups showed that the volume of the inner shell - (further -tunica intima - TI) and the volume of the capillary network in the middle shell (hereinafter - tunica media - TM) decreased with age, while the volume of the muscular component in the circular layer of TM, as the age of patients did not change, and the content of longitudinal bundles of smooth muscle cells in the outer shell (further tunica externa - TE) increased. The study of changes in vascular-tissue relations in the wall of the great saphenous vein in individuals of different age groups showed that the vascularization of the circular layer of TM is higher than in TE. In varicose veins, there is an increase in volume fraction of TI in young and adulthood, which indicates an increase in signs of fibrosis, and a decrease in the volume fraction of TI in the elderly and old age indicates the progression of sclerotic changes. Unlike the norm in all age groups with varicose disease in the TM structure, the quantitative changes of the characteristics studied by us change into qualitative ones. In the circular layer TM, a decrease in the proportion of circularly oriented beams of smooth muscle cells is accompanied by an increase in the connective tissue matrix, the proportion of whose volume increases with the age of the patients. Thus, the data obtained by us showed that with age in the wall of the great saphenous vein are in varicose disease, morphological changes that promote endothelial dysfunction increase, which can be one of the factors of formation of thrombi. Also is reduced the share of structures with contractile function in TM, which leads to venous congestion in basin of the great saphenous vein.</p></trans-abstract><kwd-group xml:lang="ru"><kwd>большая подкожная вена</kwd><kwd>варикозная болезнь</kwd><kwd>возраст</kwd><kwd>морфометрия</kwd></kwd-group><kwd-group xml:lang="en"><kwd>great saphenous vein</kwd><kwd>varicose disease</kwd><kwd>age</kwd><kwd>morphometry</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">Zabolevaniya ven/ Pod red.
