Clinical Trial Summary
The study is focused on clinical anatomy of superficial veins of lower limbs. We are mapping
their anatomy via ultrasonography. We are focusing on saphenopopliteal junction and
communicants between small saphenous vein and great saphenous vein.
Description:
Research project is focused on superficial veins of lower extremities, especially their
clinical anatomy. Superficial veins are located within the compartimentum saphenum. The
function of superficial veins is drainage of intradermal and epifascial spaces. Superficial
veins and their function are fundamental in development of chronic venous disorder. These
veins are physiologically connected with deep venous system via perforators but also between
each other via communicanting veins. Communicanting veins between small saphenous vein and
great saphenous vein have not been described yet, particularly because of their variations.
Clinically important is also the saphenopopliteal junction in the fossa poplitea. This region
features many variations, which were described in many studies. Also, the nomenclature of
saphenopopliteal juction is not standardised in comparison to the saphenofemoral junction.
Moreover, many articles are pointing out that there were not specified all potential drainage
ways of the cranial extension of small saphenous vein (extesio cranialis). Articles are
uniform neither in its prevalence nor in its terminology.
The knowledge of connections between the superficial and deep venous systems as well as
knowledge of communicanting veins between superficial veins is important for diagnosis and
proper treatment of chronic venous disorder. Variabilities of these veins can play
fundamental role in choosing the proper graft for aorto-coronary bypass grafting. The
ununiformed nomenclature of superficial veins, their communicating veins and junctions can
cause misleading preoperative diagnosis and overlooking of these structures in clinical
practise.
