[Anatomic and morphometric characteristics of the paravascular bed of human coronary vessels].
Anatomical, histological, histochemical methods have been used to investigate the cardiac paravasal bed. The morphometrical data have been mathematically analyzed and the figures have been treated by the computer. The arterial paravasal bed is represented by the arterial tracts, their branches-- the feeding vessels and the intramural network system. The venous paravasal bed includes deferent vessels, collecting veins and paravasal tracts. The paravasal bed is the main source of blood supply and venous outflow from the walls of the cardiac magistral vessels. The arterial paravasal bed of the heart undergoes certain changes already at the first stages of atherosclerosis, the changes increasing simultaneously with aggravation of the pathological processes. At the second stage of atherosclerosis structural reconstruction of the arterial bed tasks place; the paraarterial and intervascular arterial tracts, the transverse anastomoses between them, the intramural vascular networks and the feeding vessels proper (aa. arteriarum) are the first to undergo changes. The changes in the venous paravasal bed are less pronounced. The morphometrical data reliably confirm the changes occurring in the components of the paravasal bed.
