摘要

简介下肢静脉病变的发展基于血管壁的形态变化。慢性静脉功能不全时静脉壁结构的进一步重组将取决于静脉壁结构最初存在的差异。对小腿大隐静脉、肌内静脉、胫后静脉和腘静脉等主要静脉集血管壁结构的形态学和形态计量学特征进行比较分析。对 32 名因各种原因死亡的 35 至 50 岁的人和 10 名截肢者的静脉解剖材料进行了组织学研究。通过光镜和数码照片处理对静脉壁进行形态学研究。通过测定静脉壁各种膜的平滑肌和结缔组织成分的体积分数,以及测量血管壁的总厚度及其与静脉管腔的比例,对形态变化进行定量比较分析,结果表明,在显著性水平 p < 0.05 的情况下,差异具有统计学意义。尽管小腿各种静脉收集器结构的总体形态相似,但在结构上存在差异,这与平滑肌和结缔组织成分的体积分数有关。通过对小腿主要静脉集血管壁结构的形态学和形态计量学特征进行定性和定量统计对比分析,我们可以推测,在小腿肌肉-静脉泵的整体工作中,各个主要静脉集血管发挥着不平等的作用。

Comparative morphological and morphometric analysis of the structure of the wall of the calf venous collectors
Introduction. Development of venous pathology of the lower extremities is based on morphological changes in the vascular wall. Further structural restructuring of the vein wall in chronic venous insufficiency will depend on the initially present differences in the structure of their walls.Aim. To conduct a comparative analysis of morphological and morphometric features of the structure of the walls of the main venous collectors of the lower leg: the great saphenous vein, intramuscular veins, posterior tibia veins and poplitea vein.Materials and methods. Histological studies were carried out on autopsy material of the veins of 32 people who died from various causes aged 35 to 50 years and 10 amputated limbs. Morphological studies of the venous wall were carried out by light microscopy with digital photo processing.Results. A quantitative comparative analysis of morphological changes with the determination of the volume fraction of smooth muscle and connective tissue elements of various membranes of the venous wall, as well as measurement of the total thickness of the vascular wall and its ratio to the lumen of the veins showed statistically significant differences at a significance level of p < 0.05.Discussion. Despite the similarity of the general morphological picture of the structure of various venous collectors of the lower leg, structural differences were established, which concerned the volume fraction of the presence of both smooth muscle and connective tissue elements.Conclusion. The comparative qualitative and quantitative statistical analysis of morphological and morphometric features of the structure of the walls of the main venous collectors of the lower leg allows us to make an assumption about the unequal role of individual main venous collectors in the work of the muscular-venous pump of the lower leg as a whole.
