[Technical aspects of phlebography in varicosis of the lower limbs (author's transl)].

Ascending phlebography is a safe and reliable method for preinterventional differential diagnosis of primary and secondary venous insufficiency. With the combined use of fluoroscopy and spot filming, the technique yields functional information on the venous valves and communicating veins. It also permits exact localization of peripheral and proximal varicosis and venous aneurysms. In addition, the plevic and inferior vena cava inflow can be evaluated.
