Název v původním jazyce

Three-dimensional arrangement of the Vasa vasorum in explanted segments of the aged human great saphenous vein: scanning electron morphometry of vascular corrosion cast

Popis výsledku v původním jazyce

The vasa vasorum of skeletonized and nonskeletonized segments of five human great saphenous veins (GSVs), harvested during coronary bypass grafting, were cannulated, rinsed, and injected (casted) with the polymerizing resin Mercox-C1-2B. After removal ofthe dry vascular tissue, the casts were examined using scanning electron microscopy. Stereopaired images (tilt angle, 6degrees) were taken, imported into a 3D morphometry system, and the 3D architecture of the vasa vasorum (arterial and venous vasa as well as capillaries) was studied qualitatively and quantitatively in terms of vasa diameters, intervascular and interbranching distances, and branching angles. Diameters of parent (d(0)) and large (d(1)) and small (d(2)) daughter vessels of arterial and venous bifurcations served to calculate asymmetry ratios (alpha) and area ratios (beta). Additionally, deviations of bifurcations and branching angles from optimal branches were calculated for selected arterial vasa. The arrangement of the
