Abstract
In examining venous stasis of the legs most valuable information is obtained by this simple method, preferably termed the phlebographic Trendelenburg test. It renders a complete and positive evaluation of the important veins in the proximal part of the leg. The test must, as a rule, be completed with a supplementary ascending phlebogram on the lower leg at the same time (Gullmo, 1956). The localisation of pathological lower leg communicant veins, the condition of the short saphenous vein and the muscle veins in the calf are then determined. The proximal phlebographic test here described is, however, of great importance. By this test the type of the changes, if any, will always be determined.
