As a consequence of vehement development of the diagnostic and therapeutic techniques, the more detailed knowledge of anatomy, terminology, venous system variants and venous wall structure is necessary both for the phlebologists, sonographists and for the surgeons and cardiosurgeons. The histological part brings information about the content of collagen and elastin fibers in all layers of the superficial veins wall and about the arrangement of the vasa vasorum in both normal and varicose vena saphena magna.
