Abstract		Non-invasive examination in chronic venous insufficiency is a means of establishing which system is primarily affected (the deep or the superficial venous system), if the valves are damaged (valve incompetence), and to measure the effectiveness of the muscle pump. A universal diagnostic test is not available. Of all the examination methods at our disposal, the most appropriate one is colour duplex ultrasonographic venous imaging. Therefore, this method is now replacing x-ray phlebography and vein examination by continuous bi-directional Doppler ultrasound, as well as various plethysmographic methods, direct measurement of venous pressure and volumetric methods. The paper therefore presents the ultrasonographic method in greater detail. Its use allows the examination of the patency of the deep venous system and also of the saphenous trunks, but above all it is possible to precisely localise and measure the vein reflux on the lower extremities. It is suggested that ultrasonographic examination should be performed in all patients with clinically significant chronic venous insufficiency, especially before planned surgery. Other examination methods are mentioned only briefly.
Summary		Z neinvazivnimi preiskovalnimi metodami skušamo ugotoviti, ali je primarno prizadet globoki ali povrhnji venski sistem ali so okvarjene zaklopke (inkompetenca zaklopk) in izmeriti učinkovitost mišične črpalke. Enotnega diagnostičnega testa nimamo. Od vseh preiskovalnih metod, ki so nam na voljo, se zahtevam še najbolj pribljižuje dvojni barvni ultrazvočni prikaz ven. Zato ta metoda izrinja rentgensko flebografijo kot tudi pregledovanje ven s kontinuiranim dvosmernim doplerskim ultrazvokom in tudi različne pletizmografske metode, neposredno merjenje venskega tlaka in volumetrične metode. Zato je tudi ultrazvočna metoda podrobneje predstavljena. Z njo ugotavljamo prehodnost ven in tudi debel safen, predvsem pa lahko natančno lokaliziramo in tudi izmerimo reflux na venah spodnjih udov. Priporočamo, da se ultrazvočna preiskava naredi pri vseh bolnikih s klinično pomembno kronično vensko insuficienco, predvsem pa pred predvidenim kirurškim zdravljenjem. Ostale preiskovalne metode so v sestavku tokrat le na kratko omenjene.
